3(x-2) = x + 4 ...............given
3x - 6= x + 4 .................distributive property
2x - 6 = 4 ......................addition property of equality
2x = 10 .........................addition property of equality
x = 5 ..............................division property of equality
Step-by-step explanation: x+(x+2)+(x+4)+(x+6)+(x+8)+(x+10)=126
6x+30=126
6x=96
X=16
Since x is the first number , x+6 is the fourth even number .
Thus, the fourth number in the sequence is 22
Answer:
2
Step-by-step explanation:
The average rate of change of h(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ - 2, 4 ] , then
f(b) = f(4) = - (4)² + 4(4) + 12 = - 16 + 16 + 12 = 12
f(a) = f(- 2) = - (- 2)² + 4(- 2) + 12 = - 4 - 8 + 12 = 0
Then
average rate of change = 
= 
= 2
Answer:
Shrink of an exponential growth function is f(x) = 1/3(3)^x
Step-by-step explanation:
Answer:
80
Step-by-step explanation:
120 divided by 3 is 40. 40 multiplied by 2 is 80.
