Consider the expression –3(y – 5)2 – 9 + 7y.

kolbaska11 [484]

Answer: Option 'B' and 'E' are correct.

Step-by-step explanation:

Since we have given that

$-3(y-y)^2-9+7y$

Simplification needs a few steps:

$-3(y-5)^2-9+7y\\=-3(y^2+25-10y)-9+7y\\=-3y^2-75+30y-9+7y\\=-3y^2+37y-84$

So, Option 'B' and 'E' are correct.

As Option 'B' says there are 3 terms in the simplified product, which is true.

Evaluate f(-12) given f(x) = -21x - 12

frozen [14]

Answer:

The answer for the given function is f( -12 ) = 240.

Step-by-step explanation:

Given:

$f(x)=-21x-12$

To Find :

F ( -12 ) = ?

Solution:

Function:

A function is like a machine that gives an output for a given input.
A function has an independent variable which is called the input of the function.
The output for a given input is called the dependent variable.

For Example

f ( x ) = x + 3

x = independent variable

f ( x ) = Output for a given input

Here we have

$f(x)=-21x-12\\Put\ x=-21\\\therefore f(-12) = -21\times -12 - 12\\\therefore f(-12) = 252 - 12\\\therefore f(-12) = 240$

Therefore f(-12) = 240

NEED THIS NOW!!!!!!!!!!!!!!!! PLEASE

FrozenT [24]

I think the answer is basketball players' gender does not seem to affect shoe preference for the players in the survey. I believe this because both genders prefer the same thing, so the gender won't matter since they both prefer hightop shoes. If they preferred different shoes, then it would matter.
Hope this helps.

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.
