Answer:
y = -6x + 7 has greater rate of change
Step-by-step explanation:
for the first one, the rate of change is -6x and for the second one, the rate of change is -5x so the rate of change for y = -6x + 7 is greater.
Use the formula y2 - y1 / x2 - x1 to find the slop for the second equation. the second equation is y = -5x
<u>Solving</u>
Knowing that we have the information needed we will first find the perimeter of the rectangle.
Rectangle:
Length: 13cm
Width: 7cm
Formula: L+L+W+W
13+13+7+7 = 40cm
Meaning the perimeter is 40cm and we can use this to find the length of a square. From general knowledge we know that all sides of a square is equal.
So if we divide the 4 sides by 40 we will get our answer.
40 ÷ 4 = 10
So B would be our answer...
<u>Statement</u>
<u />
Therefore the length of a side of the square is 10cm, meaning answer B is correct.
Answer:

Step-by-step explanation:
we know that
----> by supplementary angles (form a linear pair)
Solve for x
Combine like terms

subtract 99 both sides

Divide by 3 both sides

Answer:
4d+2m+13
Step-by-step explanation:
DECA=10, decagon = 10 sides.
since each side is 1.8 long, all 10 sides will be 10*1.8 or 18 units long, so that'd be the perimeter then,
