Answer:
Slope=-1
Step-by-step explanation:
slope is ΔY/ΔX
ΔX = 3 – -5 = 8
ΔY = -1 – 7 = -8

What is the slope of the line.
Answer:
1/3
Step-by-step explanation:
I have a certain way of doing this, I will start from the Y-intercept, let's say its (0, 2), then, if the next point is (3, 4) i will count up 1, to get to point 3 on the graph, then count left/right to point 4. Thus making my slope 1/2.
Hope that made sense!

Answer:
44 inches
Step-by-step explanation:
The sides of a rhombus are all the same length, so we have ...
AB = BC
3x -4 = 2x +1
x = 5 . . . . . . . . . add 4-2x
Then the side lengths are ...
3x -4 = 3·5 -4 = 11
Four of them total 4·11 = 44 inches.

Answer:
[tex]-6x^2\left(3x^5\right)=-18x^7[/tex]
Hence, option (A) is true.
Step-by-step explanation:
Given the expression
[tex]-6x^2\left(3x^5\right)[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]
i.e. [tex]x^2x^5=\:x^{2+5} \\[/tex]
so the expression becomes
[tex]-6x^2\left(3x^5\right)=-6\cdot \:\:3x^{2+5}[/tex]
[tex]\mathrm{Add\:the\:numbers:}\:2+5=7[/tex]
[tex]=-6\cdot \:3x^7[/tex]
[tex]\mathrm{Multiply\:the\:numbers:}\:6\cdot \:3=18[/tex]
[tex]=-18x^7[/tex]
Therefore,
[tex]-6x^2\left(3x^5\right)=-18x^7[/tex]
Hence, option (A) is true.
Tiana compares the length of a name on a nameplate to the number of letters in the name. She draws the scatterplot below, and then she plots and determines an equation for the trend line. Nameplates A graph has letters on the x-axis and length (inches) on the y-axis. A trend line goes through points (2, 5) and (4, 8). The regression equation is y = 1.47 x + 2.05. Based on the information above, which is the best estimate of the number of letters that a name contains if the nameplate is 6 inches long? 3 4 10 12
Answer:
3
Step-by-step explanation:
The best estimate of the number of letters that a name contains is if the nameplate is 6 inches long will be 3. Option A is correct.
What is a scatter plot?Scatter plots are graphs that represent individual points of data and are labeled with quantitative values on both coordinate axes, meaning that there is only one projection on the x-axis and one projection on the y-axis for each point.
It is given that, the regression equation is y = 1.47 x + 2.05.
The name's letter count is represented by variable x, whereas the name's length on a nameplate is represented by variable y.
The nameplate is 6 inches long, so y=6 and you can find x by doing the following:
6=1.4x+2.05
1.4x=6-2.05
1.4x=3.95
x=2.69
x≈3
Thus, the best estimate of the number of letters that a name contains is if the nameplate is 6 inches long will be 3. Option A is correct.

Solve for m: -8 = m/-10 - 16
Answer:
m = -80
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
-8 = m/-10 - 16
Step 2: Solve for m
Add 16 to both sides: 8 = m/-10Multiply -10 on both sides: -80 = mRewrite: m = -80Answer:
We have this equation:
-8 = m/-10 -1
We can add 8 at both sides:
-8 + 8 = m/-10 -16 + 8
0 = m/-10 -8
Now, we can multiply -8 by -10 with the objective of having the same denominator (-10) in all numbers:
0 = m/-10 - 8*(-10)/-10
0 = m/-10 +80/-10
Now, we can delete all denominators
0 = m + 80
And we can say m = -80
Now, we can replace it to see if it's true:
-80/-10 - 16 = -8, so we know that's true
-80/-10 -16 = 8 - 16 = -8 ..

On a recent day, 8 euros were worth $9 and 24 euros were worth $27. Enter an equation of the form y = kx to show the relationship between the number of euros and the value in dollars. Let y be the value in dollars and x be the number of euros.
Answer:
y=1.125x
Step-by-step explanation:
9/8 is the ratio
so, I would do 9/8 which is 1.125. so, one euro is worth 1.125 dollar
y(dollars)=1.125x(euros)
TEST
27 dollars=1.125 • 24

Nasreen was babysitting her cousin on Saturday.
She brought him to the park and spent $4.25 at
the ice cream truck. If she was paid $30.00 for
babysitting, how much did Nasreen profit for the
afternoon?
Answer:
$25.75
Step-by-step explanation:
$30.00 - $4.25 = $25.75
What is the x-coordinate of the point of intersection for the two lines below?
(2x + y = -9
(2x - 5y =-3
Answer:
From the graph, it is clear that the point of intersection is:
(x, y) = (-4, -1)And the x-coordinate of the point of intersection for the two lines is:
x = -4Step-by-step explanation:
As we know that the solution of the system of equations is the point of intersection. Let us solve it.Given the system of equations
[tex]\begin{bmatrix}2x+y=-9\\ 2x-5y=-3\end{bmatrix}[/tex]
solving the system of equations
subtracting 2x+y = -9 from 2x-5y = -3
[tex]2x-5y=-3[/tex]
[tex]-[/tex]
[tex]\underline{2x+y=-9}[/tex]
[tex]-6y=6[/tex]
so
[tex]\begin{bmatrix}2x+y=-9\\ -6y=6\end{bmatrix}[/tex]
solving for y
[tex]-6y=6[/tex]
Divide both sides by -6
[tex]\frac{-6y}{-6}=\frac{6}{-6}[/tex]
[tex]y=-1[/tex]
[tex]\mathrm{For\:}2x+y=-9\mathrm{\:plug\:in\:}y=-1[/tex]
[tex]2x-1=-9[/tex]
[tex]2x=-8[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}=\frac{-8}{2}[/tex]
[tex]x=-4[/tex]
Thus, the x-coordinate of the point of intersection for the two lines below will be:
[tex]x=-4[/tex]
Also, the graph is attached.
From the graph, it is clear that the point of intersection is:
(x, y) = (-4, -1)And the x-coordinate of the point of intersection for the two lines is:

15 + 15 + 10 + 10 + 10 = 60/5 = 12 ( CODE WORD)
Step-by-step explanation:
1. There are different forms of linear equations. Slope intercept has it's equation y = mx + b
2. A proportional relationship has a constant rate of change.
ex: y =2x +5, then the rate of change is 2 and it only ever rises by 2.
3. A proportional relationship must pass through the origin in order to be a proportional relationship.
4. The variable M in slope-intercept form represents the slope. B represents the Y-intercept.
5. Standard form for a linear equation is Ax+By=C. Y = MX+B is slope-intercept form.
CODE WORD: 12 or Twelve is correct because 12 is the mean of all 5 answers.
