Mia is three years older than twice her sister brooke's age. The sum of their ages is less than 30. what is the greatest age Bro

Pachacha [2.7K]

Answer: 9

Step-by-step explanation: You can start by setting this up as an equation, where X is Brooke’s age.

X + 2(x)+ 3 = 30

The 2(X) + 3 signifies the part of the problems identifying that Mia is twice her sisters age plus 3 years.

Combine x’s

3x + 3 = 30

Subtract 3 from both sides to isolate the x term

3x= 27

Divide both sides by 3 to reduce to a single x

X= 9 , which is brooke’s age

Given g(x) = −3x + 4

Goshia [24]

Answer:

The average rate of change of g from x = a to x = a + h is -3.

Step-by-step explanation:

We are given the function:

$g(x) = -3x + 4$

And we want to determine its average rate of change of the function for x = a and x = a + h.

To determine the average rate of change, we find the slope of the function between the two points. In other words:

$\displaystyle \text{Avg} = \frac{g(a + h) - g(a) }{(a + h ) - a}$

Simplify:

$\displaystyle \begin{aligned} \text{Avg} &= \frac{g(a + h) - g(a) }{(a + h ) - a} \\ \\ &=\frac{(-3(a+h) + 4) - (-3a+4)}{h} \\ \\ &= \frac{(-3a -3h + 4) + (3a - 4) }{h} \\ \\ &= \frac{-3h}{h} \\ \\ &= -3\end{aligned}$

In conclusion, the average rate of change of g from x = a to x = a + h is -3.

This is the expected result, as function g is linear, so its rate of change would be constant.

Let f(x) = .............

galben [10]

Answer:

Step-by-step explanation:

g(3) = -2(3)^2 -4 = 2(9) -4 = 18-4 = 14

|f(2)| = | 2^2 -3| = | 4-3| = 1

(g(3) +2) = (14+2) = 16

4* |f(2)| = 4*1 = 4

16/4 = 4
