Hello,
(9*140-180)/8=147.5
================
-12+3b-1=-5-b
Combine like terms to get:
3b-13=-5-b
Add 13 to both sides:
3b= 8-b
Add b to both sides:
4b=8
Divide both sides by 4:
4b/4=8/4
b=2
Final answer
b=2
The answer is y=-3/4+5 because y=mx+b
m:slope
(x,y):any point on the line
(0,b): y-intercept of the line
Circle = (x-h)^2 + (y-k)^2 = r^2
Center is (h,k) h = -5, k = 2
Radius is 4, r = 4
(x - -5)^2 + (y - 2)^2 = 4^2
(x + 5)^2 + (y - 2)^2 = 16
Answer:
15a^6 + 15a^2b.
Step-by-step explanation:
5a^2(3a^4 + 3b)
= 15a^6 + 15a^2b.
