Answer:
y = 4 (-3) - 2
y = -12 - 2
y = -14
Step-by-step explanation:
x = 2
step 1 :
(2 • (5x + 2) • 2) - 48 = 0
step 2 :
4 • (5x + 2) - 48 = 0
Pulling out like terms :
20x - 40 = 20 • (x - 2)
step 4 :
20 • (x - 2) = 0
Equations which are never true :
Solve : 20 = 0
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
Solve : x-2 = 0
Add 2 to both sides of the equation :
x = 2
Answer: 0.3846153846
Step-by-step explanation:
Answer:
f(7)=58
b(-2)-a(12)=-188
Step-by-step explanation:
f(7)=(7)^2+9
49+9
f(7)= 58
b(-2)-a(12)=8(-2)-14-13(12)-2
-16-14-156-2
=-188
