Group the like term 'c'
c(c-8)
This can be done in two ways
One method is to check the answer options in both f(x) and g(x) and select the one that matches for both.
The second is to form a quadratic equation and solving as such:
f(x) = g(x)
-x² + 4x + 12 = x + 8
x² - 3x - 4 = 0
(x - 4)(x + 1) = 0
x = 4; x = -1
Only x = 4 is given in the options, so the answer is B
Answer:
hello : all possible solutions for 2x+7<3x-5 is : x > 12
Step-by-step explanation:
calculate : x
2x+7<3x-5
2x - 3x <-7-5
-x < -12
all possible solutions for 2x+7<3x-5 is : x > 12

Answer:
Step-by-step explanation:
The manufacturing plant earned $80 per man-hour of labor when it opened
The plant earns an additional 5% for every additional man-hour t.
This can be modeled using the function:
where Initial Amount Earned, P=80
Rate of Increase, r=5%=0.05
Therefore, the function that models the amount earned at any time t is:
