1) (-2x+4)+(x-6) is simplified into =-x-2

2)  (uv-3)+(4uv+1)  is simplified into 5uv-2\\

3) (11x-8)-(2x+3) is simplified into -9x-11

4) (x^2-4)-(x-2) is simplified into x^2-x-2

5) (12-3t-7t^2)+(1+3t-t^2) is simplified into -8t^2+13

Step-by-step explanation:

We need to solve the polynomials.

1) (-2x+4)+(x-6)

Solving:

(-2x+4)+(x-6)\\=-2x+4+x-6\\Combining\,\,like\,\,terms:\\=-2x+x+4-6\\=-x-2

So, (-2x+4)+(x-6) is simplified into =-x-2

2) (uv-3)+(4uv+1)

Solving:

(uv-3)+(4uv+1)

Expanding:

=uv-3+4uv+1\\Combining\,\,like\,\,terms:\\=uv+4uv-3+1\\=5uv-2\\

So,  (uv-3)+(4uv+1)  is simplified into 5uv-2\\

3) (11x-8)-(2x+3)

Solving:

(11x-8)-(2x+3)

Expanding:

=11x-8-2x-3\\Combining\,\,like\,\,terms:\,\,\\=11x-2x-8-3\\=-9x-11

So, (11x-8)-(2x+3) is simplified into -9x-11

4) (x^2-4)-(x-2)

Solving:

(x^2-4)-(x-2)

Expanding:

=x^2-4-x+2\\Combining\,\,like\,\,terms:\\=x^2-x-4+2\\=x^2-x-2

SO, (x^2-4)-(x-2) is simplified into x^2-x-2

5) (12-3t-7t^2)+(1+3t-t^2)

Solving:

(12-3t-7t^2)+(1+3t-t^2)

Expanding:

=12-3t-7t^2+1+3t-t^2\\Combining\,\,like\,\,terms:\\=12+1-3t+3t-7t^2-t^2\\=13+0t-8t^2\\=-8t^2+13

So, (12-3t-7t^2)+(1+3t-t^2) is simplified into -8t^2+13

Answer:

f(-14) = -6

f(-4) = 6

f(12) = 6

f(0) = -3

negative

Step-by-step explanation:

f(-14) = -6

This is because when x is -14, y is -6, as seen in the graph

f(-4) = 6

This is because when x is -4, y is 6, as seen in the graph

f(12) = 6

This is because when x is 12, y is 6, as seen in the graph

f(0) = -3

This is because when x is 0, y is -3, as seen in the graph

is f(4) positive or negative?
negative

This is because when x is 4, y is -6, as seen in the graph

Answer:

21 C

22 B

23 169

Step-by-step explanation:

21 3m mean 3 times a certain number

22 the negative make the 4 go negative and the -5 positive

23 i did 5^2-4^2= 9

then 6^2 divided by 9+9= 13 i took the 9 from the 5^2 problem then divided it by 6^2

then 13 x 13 = 169

The sum of eight times a number and fifteen is seven
asambeis [7]
8x+15=7

In the statement the phrase the sum of can tell you that it is going to be an addition problem. So 8x ( eight times a number) would be added to the 15, 8x+15. Since its an addition problem the part where it says ' ... is seven', you know that it will all equal 7. So the answer would be 8x+15=7.
