What is the slope-intercept form of the equation y - 7= -5/2(x+4)
1 answer:
The first thing I would probably do is distribute (multiply) the -5/2 into the parenthesis:
= (-5/2)x + (-20/2)
Notice how I am not putting the x into the fraction. This is to make it easier to see the slope-intercept form.
Lets simplify the (-20/2) and then add 7 to both sides:
y - 7 = (-5/2)x - 10
y = (-5/2)x - 3
Your answer would then be:
y = (-5/2)x - 3
y = mx + b
Since it is now in the requested format.

L=2w-6
area = L x W
108=(2w-6)w
108 = 2w^2-6w
2w^2-6w-108 = 0
2(w^2-3w-54)=0
2(w-9)(w+6) = 0
w=9
L= 2(9)-6 = 12
12*9 = 108
28^2=784
29^2=841
784<830<841
therefore sqrt784<sqrt830<sqrt841
therefore 28<sqrt830<29
Done!

Step-by-step explanation:
a−(6a−(5a−8))
a-(6a-5a+8)
a-6a+5a-8
6a-6a-8
0-8
=-8
so the answer doesn't depend on a
Answer: first one 5.55
Step-by-step explanation:
-4x+8=42
-4x+8-8=42-8
-4x=34
-4x=34
-4x/-4=34/-4
x= - 17/3
