Write an equation in slope-intercept form of the line shown. (3,1) (1,-3)
Answer:
[tex]y = 2x - 5[/tex]
Step-by-step explanation:
The first step in finding the equation of a line from a given set of points is to find its slope. The slope of a line is defined by the formula:
[tex]m = \dfrac{\textrm{rise}}{\textrm{run}} = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
In this problem, we are given two points in the form [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex].
So, we can define the x's and y's as:
[tex]x_1 = 3[/tex], [tex]y_1 = 1[/tex], [tex]x_2 = 1[/tex], [tex]y_2 = -3[/tex].
Hence, the slope of the line can be solved for.
[tex]m = \dfrac{-3 - 1}{1 - 3}[/tex]
[tex]m=\dfrac{-4}{-2}[/tex]
[tex]m = 2[/tex]
So, the slope of the line is 2.
Now, we can plug this into the point-slope equation for a line where (a, b) is a point on the line and m is its slope.
[tex]y - b = m(x - a)[/tex]
I will use the point (3, 1):
[tex]y - 1 = 2(x - 3)[/tex]
and isolate y to put it into slope-intercept form.
[tex]y - 1 = 2x - 6[/tex]
[tex]y = 2x - 6 + 1[/tex]
[tex]y = 2x - 5[/tex]
So, the equation in slope-intercept form for the line that goes through the points (3, 1) and (1, -3) is [tex]y = 2x - 5[/tex].

Find the equation of the line passing through the given point and parallel to the given line.
( -1 , -1 ), x + y = 8
( -5 , -2), y + 3x = 10
The equation of the line that passes through (-1, -1) and is parallel to x + y = 8 is x + y = -2
The equation of the line that passes through (-5, -2) and is parallel to y + 3x = 10 is 3x + y = -17
Equation of a lineFrom the question, we are to determine the equation of the line passing through the given points and parallel to the given line.
NOTE: If two lines are parallel, then their slopes are equal
First, we will determine the slopes of the given line
x + y = 8
Write the equation in the slope-intercept form, y = mx + b
Where m is the slope
and b is the y-intercept
x + y = 8 becomes
y = -x + 8
Therefore, m = -1
Now, we will determine the equation of a line that has a slope of -1 and that passes through (-1, -1)
Using the point-slope form of the equation of a straight line,
y - y₁ = m(x - x₁)
y - (-1) = -1(x - (-1))
y + 1 = -1(x + 1)
y + 1 = -x -1
x + y = -1 -1
x + y = -2
Hence, the equation is x + y = -2
Now, we will determine the slope of y + 3x = 10
Express the equation in slope-intercept form
y + 3x = 10
y = -3x + 10
Therefore, m = -3
Now, we will determine the equation of a line that has a slope of -3 and that passes through (-5, -2)
Using the point-slope form of the equation of a straight line,
y - y₁ = m(x - x₁)
y - (-2) = -3(x - (-5))
y + 2 = -3(x + 5)
y + 2 = -3x - 15
3x + y = -15 -2
3x + y = -17
Hence, the equation is 3x + y = -17

You receive two sales job offers. One company offers a straight commission of 5% of sales. The other company offers a salary of $500 per week plus 2% of sales. How much would you have to sell in a week in order to make the straight commission job offer better? (Round your answer to the nearest cent.)
To make straight commission the better offer, you would have to sell (more than, less than, equal to) $____ per week.
Answer:
To make straight commission the better offer, you would have to sell more than $16666.67 per week.
Step-by-step explanation:
Set inequality, assuming the sales amount is x:
5% of x > 500 + 2% of x0.05x > 500 + 0.02x0.05x - 0.02x > 5000.03x > 500x > 500/0.03x > 16666.67 (rounded to the nearest cent)Answer:
More than $16,666.67.
Step-by-step explanation:
Define the variables:
Let x = Weekly sales (in dollars).Let y = Total salary (in dollars).Create an equation for each job offer using the defined variables and given information.
Job Offer 1
Straight commission of 5% of sales:
[tex]\implies y=0.05x[/tex]
Job Offer 2
A salary of $500 per week plus 2% of sales:
[tex]\implies y=500+0.02x[/tex]
For Job Offer 1 to be better, set the expression for this offer to be greater than the expression for Job Offer 2 and solve the inequality:
[tex]\implies 0.05x > 500+0.02x[/tex]
[tex]\implies 0.05x-0.02x > 500+0.02x-0.02x[/tex]
[tex]\implies 0.03x > 500[/tex]
[tex]\implies \dfrac{0.03x}{0.03} > \dfrac{500}{0.03}[/tex]
[tex]\implies x > 16666.66666...[/tex]
Therefore, to make straight commission (Job Offer 1) the better offer, you would have to sell more than $16,666.67 (nearest cent) per week.

Kevin planted ome corn in the back yard and meaure it height regularly. Currently, the talk are 75 inche tall. That i 25% taller than the lat time he checked. How tall were the talk then?
The height of the tree was 56 inches.
We can calculate the percentage of a certain amount by :
Subtracting New - Original / New multiplied by 100
this implies it will be
75 - x / 75 × 100 = 25 %
7500 - 100 x = 1875
this implies 7500 - 1875 = 100 x
5625 = 100 x
Thus , On dividing both sides by 100 we get
56.25 = x
Now on rounding off this number we will get
56 = x
Thus the original height of the corn plant was 56 inches

For every necklace, four times the number of glass beads is less than or equal to 8 more than twice the number of clay beads. Each clay bead costs $0.20 and each glass bead costs $0.40. The company wants to find the minimum cost to make a necklace with clay and glass beads and find the combination of clay and glass beads in a necklace that costs the least to make. a. Define the variables and write a system of inequalities. Then write an equation for the cost C. b. Graph the system of inequalities and find the coordinates of the vertices of the feasible region. c. Find the number of clay beads and glass beads in a necklace that costs the least to make.
a. The system of inequalities that models the situation is:
0 ≤ x ≤ 10.y ≥ 4.4y ≤ 8 + 2x.The equation for the cost is: C(x,y) = 0.2x + 0.4y.
b. The graph is given by the image at the end of the answer, and the vertices are (4,4), (10,4) and (10,7).
c. The number of clay beads and glass beads in a necklace that costs the least to make is: 4 clay beads and 4 glass beads.
What is the system of inequalities?The variables for the system are presented as follows:
Variable x: number of clay beads used.Variable y: number of glass beads used.Each necklace has no more than 10 clay beads and at least 4 glass beads, hence the constraints are listed as follows:
0 ≤ x ≤ 10.y ≥ 4.The numbers of each beads are countable amounts, meaning that they cannot assume negative values.
Four times the number of glass beads is less than or equal to 8 more than twice the number of clay beads, hence the final constraint is of:
4y ≤ 8 + 2x.
Each clay bead costs $0.20 and each glass bead costs $0.40, hence the cost function is given as follows:
C(x,y) = 0.2x + 0.4y.
Using the three constraints, the graph is given by the image at the end of the answer, and the vertices are as follows:
(4,4).(10,4).(10,7).The minimum cost is at the vertex with the smallest numeric value of the cost function, hence the numeric values are listed as follows:
C(4,4) = 0.2(4) + 0.4(4) = 2.4. -> minimum cost.C(10,4) = 0.2(10) + 0.4(4) = 3.6.C(10,7) = 0.2(10) + 0.4(7) = 4.8.More can be learned about a system of inequalities at https://brainly.com/question/9195260

The point-slope form of the equation of a line that passes through points (8, 4) and (0, 2) is y - 4 = 1/4(x-8)
the slope-intercept form of the equation for this line?
The equation for the line that runs between the points (8, 4) and (0, 2) has the following slope-intercept form is : y = 1/4 x + 2
What is equation of line?The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.
Here,
A line's equation can be written as y = mx + b in slope-intercept form.
slope = m and y-intercept = b.
You can rewrite the equation in point-slope form as y = mx + b.
Given,
y - 4 = 1/4 (x - 8)
Change the formula to y = mx + b.
So,
y - 4 = 1/4 x - 2
We have to add 4 on both sides,
y - 4 + 4 = 1/4 x - 2 + 4
y = 1/4 x + 2
As a result, the equation of the line passing through the points (8, 4) and (0, 2) has the slope-intercept form is y = 1/4 x + 2 .

1) A sales representative earns a 2.5% commission on sales. Find the commission earned when the total sales are $80,500.
2 p varies directly as q and the square of r and inversely as s.
a. Write the equation of the relation.
b. Find kif p = 40 when q = 5, r = 4 and s = 6.
c. Find p when q = 8, r= 6 and s= 9.
d. Finds when p= 10, q=5 and r = 2.
The equation for the relation is [tex]p=k \frac{qr^2}{s}[/tex].
The value of k when q = 5, r = 4 and s = 6 is 3.
The value of p when q = 8, r= 6 and s= 9 is 96.
The value of s when p= 10, q=5 and r = 2 is 6.
A connection between two different items is called variation. There are two categories of difference. Direct Variation is the name of the first one. When two variables move in the same direction, direct variation occurs. Additionally, as one variable rises, the other variable rises as well. Inverse Variation is the second kind. When the two variables move in the opposite direction, inverse variation occurs. Additionally, this occurs when one variable rises while the other falls.
Since p varies directly as q and the square of r and inversely as s. So the equation will be [tex]p=k \frac{qr^2}{s}[/tex].
Now, finding the value of k, for p = 40 when q = 5, r = 4 and s = 6,
[tex]p=k \frac{qr^2}{s}\\40=k \frac{5\times4^2}{6}\\k = 3[/tex]
Now, finding the value of p when q = 8, r= 6 and s= 9,
[tex]p=3 \frac{8\times 6^2}{9}\\=96[/tex]
Now, finding the value of s when p= 10, q=5 and r = 2,
[tex]10=3 \frac{5\times 2^2}{s}\\\\10=3\times \frac{20}{s}\\s=6[/tex]
Therefore, the equation for the relation is [tex]p=k \frac{qr^2}{s}[/tex] , the value of k when p = 40 when q = 5, r = 4 and s = 6 is 3, the value of p when q = 8, r= 6 and s= 9 is 96 and the value of s when p= 10, q=5 and r = 2 is 6.
