Answer:

A.

${ \tt{f(x) = - 4 {x}^{2} + 9x }}$

Step-by-step explanation:

${ \tt{f(x) = x( - 4x + 9)}}$

For this case we have the following functions:

$f (x) = x ^ 2-3x + 7\\g (x) = x + 3$

Equalizing we have:

$x ^ 2-3x + 7 = x + 3\\x ^ 2-3x-x + 7-3 = 0\\x ^ 2-4x + 4 = 0$

To solve we factorize, that is, we look for two numbers that when multiplied give a result of 4 and when added together give a result of -4. These numbers are -2 and -2.

$-2-2 = -4\\(-2) * (- 2) = 4$

Thus, we have:

$(x-2) (x-2) = 0\\(x-2) ^ 2 = 0$

So, the solution is $x = 2$

Answer:

$x=2$

Solve the equation -7y + 4 =60 *<br> Pls, help me answer this.

natita [175]

Answer: -8
Here’s why: you start by subtracting the 4 from both sides. Leaving you with
-7y= 56
Divide by -7 on both sides
-7y/-7 = y 56/-7=-8

Alicia had $-11 in her checking account. She did a few chores and made 44.50. She decided to pay for her friend to go the movies

Mademuasel [1]

44.50-11= 33.50

6.25x2= 12.50

33.50-12.50= 21$

She has 21$ left over
