Write the equation of the line that passes through the points (7, –9)
and (1,-4). Put your answer in fully reduced point-slope form,
unless it is a vertical or horizontal line.
Answer:
y=[tex]\frac{-5}{6}[/tex]x+14[tex]\frac{5}{6}[/tex]
Step-by-step explanation:
The equation of a line is y=mx+b
to find the equation of the line you need its gradient(m) and its y intercept(b)
the gradient is
[tex]\frac{y1-y2}{x1-x2}[/tex]
y1= the y value of the first point which is -9
y2=the y value of the second point which is -4
x1=the x value of the first point which is 7
x2=the x value of the first point which is 1
then input the values into the equation
[tex]\frac{(-9)-(-4)}{(7)-(1)}[/tex]
=[tex]\frac{-9+4}{6}[/tex]
=[tex]\frac{-5}{6}[/tex]
to find the y just times the x by the gradient and then minus it from the y
-9-(7 x [tex]\frac{-5}{6}[/tex])=14[tex]\frac{5}{6}[/tex]
making the equation y=[tex]\frac{-5}{6}[/tex]x+14[tex]\frac{5}{6}[/tex]

A produção mensal de uma Olaria é de 5.000 tijolos nesse mês alvará produziu 3925 tijolos quantos tijolos ainda falta para completar a produção mensal
Responda:
1075 tijolos
Explicação passo a passo:
Dado que:
Número de tijolos produzidos Mensalmente = 5.000 tijolos
A quantidade de tijolos produzidos por licença = 3925
O número de tijolos que ainda faltam no valor mensal desejado:
Quantidade de produção mensal - quantidade produzida por licença
5000 - 3925 = 1075 tijolos

Answer:
None of the given functions
Step-by-step explanation:
Given
[tex]A)\ f(x) = 3x + 7[/tex]
[tex]B)\ f(x) = x^3 - 2x^2 +x - 5[/tex]
[tex]C)\ f(x)=2x - 3[/tex]
[tex]D)\ f(x)=x^2 - 7x + 4[/tex]
Required
Which do not have set of real numbers as its domain
If a function has no root and no denominator, then the domain of such function is a set of all real numbers
The given functions (a) to (d) do not have square roots and do not have denominators.
Hence, all functions have the set of real numbers as their domain
Convert 7x - y = -9 to slope-intercept form. Simplify your answer.
The equation of a line, 7x - y = -9, converted to slope-intercept form is: y = 7x + 9
Equation of a line in Slope-intercept FormIf "m" is the slope of a line and "b" is the y-intercept, the equation of the line in slope-intercept form is given as: y = mx + b.
Thus, given the equation, 7x - y = -9, rewrite/convert to slope-intercept form as follows:
7x - y = -9
-y = -7x - 9
Divide both sides by -1y = 7x + 9
Therefore, the equation of a line, 7x - y = -9, converted to slope-intercept form is: y = 7x + 9

Is it possible to use dynamic geometry software to draw a triangle with
angles of 50°, 65°, and 70°? Explain.
Answer:
no
Step-by-step explanation:
The sum of the angles of a triangle must be equal to 180
50+65+70
185
This is not equal to 180 so it does not make a triangle
m(x)=-5/3x+4
Find m(3)
Answer:
-1
Step-by-step explanation:
Please enclose the fractional coefficient inside parentheses:
m(x) = (-5/3)x + 4
To find m(3), replace x in the above equation with 3:
m(3) = (-5/3)(3) + 4 = -5 + 4 = -1

Which graph represents the solution set of - 4x - y <- 6?
Answer: it’s D
Step-by-step explanation:
The Linear Inequality - 4x - y <- 6 represents option d, of the solution set.
What is Linear Inequality?
Expressions using linear inequalities compare any two values using inequality symbols like "," ">," "," or "." These values might be either numerical, algebraic, or both. Examples of numerical inequality include 1011 and 20>17, whereas algebraic inequalities include x>y, y19-x, and x z > 11 (also called literal inequalities). The mathematical equation when both sides are not equal is called an inequality. Inequality occurs when a connection compares two expressions or two numbers in an unequal manner. In this instance, any of the inequality symbols, such as greater than symbol (>), less than symbol (), greater than or equal to a symbol (), less than or equal to a symbol (), or not equal to a symbol (), is used in place of the equal sign "=" in the phrase. Polynomial inequality, rational inequality, and absolute value inequality are the many sorts of inequalities. The symbols "and ">" signify tight inequalities, whereas " and "signify slack inequalities. A linear inequality looks precisely like a linear equation, but the symbol connecting two expressions is different.
In the given question, we have given the graph of the inequality 4x - y <- 6, So, we need to find the best suitable graph that represents the graph of the given Inequality.
So, the Inequality is:
- 4x - y <- 6.
So, we can substitute the value of x and y;
So, substitute x = 1;
So, The y value will be less than 2;
That is:
y < 2;
Again let's put the value of x = -1;
we get the value of y as less than 10.
y<10;
So, by substituting the values as mentioned we can see that the value of y is decreasing.
So, by plotting the values in the graph, we can get the correct graph.
Hence, The correct answer is option d.

10 and 20 are the initial amounts, so they don't get a variable. The 3 dollars and 2 dollars every mile gets the variable since the occur every mile.
The equations are:
Blank 1: 3x + 10
Blank 2: 2x + 20
To find when they are equal, we equal the equations together.
3x + 10 = 2x + 20
x = 10
Plug 10 into either equation and solve.

A small business is looking for rectangular warehouses to store extra merchandise. Warehouse A has an area of 6900 ft2. Warehouse B is half as wide and one-third as long. How many square feet is Warehouse B?
Answer:
The area of the warehouse B is 1150 square feet.
Step-by-step explanation:
Let [tex]x[/tex], [tex]y[/tex] are the width and length of the warehouse A, in inches. The areas of the each warehouse are described below:
[tex]A_{A} = x\cdot y[/tex] (1)
[tex]A_{B} = \left(\frac{1}{2}\cdot x \right)\cdot \left(\frac{1}{3}\cdot y \right)[/tex] (2)
Where:
[tex]A_{A}[/tex] - Area of the warehouse A, in square inches.
[tex]A_{B}[/tex] - Area of the warehouse B, in square inches.
If we know that [tex]A_{A} = 6900\,ft^{2}[/tex], then by (1) and (2) we have the following equation:
[tex]A_{B} = \frac{1}{6}\cdot A_{A}[/tex]
[tex]A_{B} = 1150\,ft^{2}[/tex]
The area of the warehouse B is 1150 square feet.

A salesperson had $240, 000 in sales last year, which is 60% of the sales she had this year. Which equation could be used to determine x, the salesperson's total amount of sales, in dollars, for this year?
Answer: $400,000
Step-by-step explanation:
Let the salesperson's total amount of sales, in dollars, for this year be represented by x.
Therefore, 60% of x = $240,000
60/100 × x = $240,000.
0.6 × x = $240,000..
x = $240000 / 0.6
x = $400,000
Therefore, the salesperson's total amount of sales, for this year is $400,000.
Help i will give brainlist. The quotient of 2 and g is 8 can u pls show me step by step ty
Answer:
16
Step-by-step explanation:
Set up the equation: g/2 = 8
We want to get 'g' by itself, so we need to reverse the division of two. To do that, we multiply (division and multiplication go together, addition and subtraction go together) both sides by two (what you do to one side of an equation, you must do to the other).
End up with: g = 16

A swim team ordered 36 jackets that each cost the same amount. The total cost of the order was $1,116. Let c be the cost of each jacket. How much did each jacket cost?
Answer:
c = $1116/36
c = $31
Step-by-step explanation:
the cost of each jacket can be determined by dividing the total cost of the 36 jackets by the number of jackets bought
cost of each jacket = total order cost / total number of jackets bought
$1116 / 36 = $31
Each jacket costs $31
