Let f(x) = x + 7 and g(x) = x − 4. Find f(x) ⋅ g(x). (1 point) x2 − 3x −28 x2 − 3x − 11 x2 + 3x − 28 x2 + 3x − 11

slavikrds [6]

$f(x)=x+7\\g(x)=x-4\\f(x)*g(x)=(x+7)(x-4)\\f(x)*g(x)=x^2+3x-28$

So it's x^2+3x-28

Create a factorable polynomial with a GCF of 6. Rewrite that polynomial in two other equivalent forms. Explain how each form was

lubasha [3.4K]

OK well take out the 6 for the first form

= 6(2x^2 + x + 4)

Also we can factor the first 2 terms to give the second form:-

= 6x(2x + 1) + 24

F 9 is added to twice a number and this sum is multiplied by 4, the result is the same as if the number is multiplied by 4 and

riadik2000 [5.3K]

Let
x---------> the number

we know that
[9+2x]*4=4x+12
36+8x=4x+12
8x-4x=12-36
4x=-24
x=-24/4
x=-6

the answer is
-6

The point (2, –4) is reflected across the line y = –1. What are the coordinates of the image?

schepotkina [342]

ANSWER

The coordinates of the image are (2,2)

EXPLANATION

The mapping for a reflection across the line y=k is :

$(x,y)\to (x,2k-y)$

We want to find the image of the point (2,-4) after a reflection in the line y=-1.

In this case k=-1.

$(2, - 4)\to (2,2( - 1)- - 4)$

This simplifies to,

$(2, - 4)\to (2, - 2 + 4)$

$(2, - 4)\to (2, 2)$

Hence the image is (2,2)
