x - 14 + 2x + 20 = 90
First, combine like terms: x and 2x, -14 and 20.
x + 2x = 3x
-14 + 20 = 6
3x + 6 = 90
Subtract 6 from both sides.
3x = 84
Divide both sides by 3
x = 28
Answer:
y = -4/7x + 2
Step-by-step explanation:
So to find the slope intercept form, you have to get the equation to look like: y=mx+b. To do that, you need y on one side and all of the other variable on the other side. So the first thing you have to do is subtract 4x from both sides to get
7y = 14 - 4x
To isolate the y, you have to divide both sides by 7 to get
y = 2 - 4/7x
Now, put this is y=mx+b to get
<u>y = -4/7x + 2</u>

Answer:25 lawns
Step-by-step explanation:
If u set up a proportion of 5lawns/8 hrs =x/40hrs. 8 times 5 is 40 so 5 times 5 is 25
Step-by-step explanation:
y²-y¹/x²-x¹
(-15)-(12)/4-(-2)
-3/6
=-0.5
y=mx+b
12=-0.5(-2)+b
12=1+b
12-1=b
11=b
