35x – 13 x = x – 1
⇒ 22 x = x - 1
⇒ 22x - x = -1
⇒ 21x = -1
⇒ x = -1/21
Thus,the value of x is -1/21
10x + 25 = $145
10x = $120
x =10
The number of poses is 10
Point slope form is :
8+12 = m(9-4)
8+12= 9m -4m
20= 5m
20/5= 5m/5
m= 4
Slope form
8= 4(9) +b
8= 36+b
-28=b
Y= 4x -28
Answer:
d. 18a² - 12a
Step-by-step explanation:
f(x) = 2x² + 4x
f(-3a) = 2(-3a)² + 4(-3a)
2(-3a)² + 4(-3a)
2(9a²) + (-12a)
18a² - 12a
