F(x) = -52x + 4

g(x) = -12x - 4

To find the solution of the system of equation, we have to just equate the equation to each other.

f(x) = g(x)

-52x + 4 = -12x - 4

-52x + 12x = - 4 - 4

-40x = -8

x = \frac{-8}{-40} =  \frac{8}{40} =\frac{1}{5}

x = 0.2

A ball is thrown upward from the top of a building. The function below shows the height of the ball in relation to sea level, f(
gavmur [86]
We have the following function:
 f(t) = −16t2 + 34t + 546
 By definition, the average rate of change is:
 Avr = (f (t2) - f (t1)) / (t2 - t1)
 We have then:
 For t1 = 5:
 f (5) = -16*(5)^2 + 34*(5) + 546
 f (5) = 316
 For t2 = 5:
 f (7) = -16*(7)^2 + 34*(7) + 546
 f (7) = 0
 Substituting values:
 Avr = (0 - 316) / (7 - 5)
 Avr = -158
 Answer:
 The average rate of change of f (t) from t = 5 seconds to t = 7 seconds is -158 feet per second.

Which number is represented by the number line
denpristay [2]

Answer: B

Step-by-step explanation: The number line has tally marks up to 3, so 3 has to be divided by something, meaning A and C do not work. There are 9 total tally marks circled, so the equation equals 9, leaving B as the only possible answer. Also, there are three tally marks per whole number, so each tally is 1/3, which is equal to 2/6, further proving it is B.
