Answer:
If you solve for y, the relationship is y = -x + 20. Since the equation isin the form y = mx + b with m = -1 and b = 20, the equation is linear. It is not proportional because b ≠ 0.

Can someone help me find the Slope to these to pleaseeee?
Answer:
Remember the slope formula:
m= y2-y1/x2-x1
11. (-1,3) (3,3)
= 3-3/3--1
= 0/4
m = 0
12. (1,3) (1, -2)
= -2-3/1-1
= -5/0
= undefined
For the future, know that the slope of horizontal lines is always zero and the slope of vertical lines is always undefined.

Answer:
Radius is 2.8 Circumference is 17.584 or 17.6 Rounded to the nearest Tenths
Step-by-step explanation:
1. Find circumference with the Formula C=πd
C=3.14 x 5.6
C=17.584 or 17.6 Rounded to the nearest Tenths
2. Radius is Always half of the Diameter.
5.6/2 = 2.8
2.8 is your radius.
3. If you want to check you work try the formula C=2πr to see if things checks out.
C=2 x 3.14 x 2.8
C= 17.584 or 17.6 Rounded to the nearest Tenths

6 - 3x = 2x - 24
Answer:
x=6
Step-by-step explanation:
rearrange terms, subtract 6 from both sides, simplify, subtract 2x from both sides, simplify, divide both sides by -5, and finally you get 6.
Answer:
x=6
Step-by-step explanation:
6 - 3x = 2x - 24
move the x together and the numbers together
REMEMBER: when you move a something from one side of the equation (not including multiplication and division) to the other, change the sign in-front of it (+ or -)
NOW CONTINUE WITH THE PROBLEM -->
-3x-2x = -24 - 6
now subtract,
-5x = -30
and divide -30 by -5
Since there are 2 negative numbers, the result would be positive -->
and for x, you would get:
x=6

What value of Y makes the equation true ?
Answer:
y = -5/2 or -2.5
Step-by-step explanation:
3y + 4 = -y - 6
add y to both sides
4y + 4 = -6
subtract 4 from both sides
4y + 4 - 4 = - 6 - 4
4y = -6 - 4
4y = -10
divide both sides by 4
4y/4 = -10/4
y = -10/4
y = -5/2 or -2.5
Which equation represents the relationship between the x-values and y-values in the graph?
The equation of line passes through the points (0, -5) and (5, -2) will be;
⇒ y = 3x/5 - 5
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (0, -5) and (5, -2).
Now,
Since, The equation of line passes through the points (0, -5) and (5, -2).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (- 2 - (-5)) / (5 - 0)
m = 3 / 5
m = 3/5
Thus, The equation of line with slope 3/5 is,
⇒ y - (-5)= 3/5 (x - 0)
⇒ y + 5 = 3x/5
⇒ y = 3x/5 - 5
Thus, The equation of line passes through the points (0, -5) and (5, -2) will be;
⇒ y = 3x/5 - 5

Please help! I need this correct,
Answer:
A. 56
Step-by-step explanation:
If you look at the image, I cut the shape in half.
So the shape on the bottom not can be multiplied as such: 8x2x2
8x2=16 then 16x2=32.
Since the shape cut in half, the sides are now 2 instead of 4.
Now you can multiply the top shape by: 2x6x2
2x6=12 then 12x2=24.
After you have the volume of both shapes, you add the volumes together.
32+24=56 Then your answer should be A. (Hope this helps!)
