6) Nine less than a number: x-9

7) The product of nine and a number: 9n

Step-by-step explanation:

You have to match statements with their mathematical expressions.

I will match the statements with their mathematical forms.

1) Three increased by a number: 3+x

2) The sum of nine and eight: 9+8

3) Nine divided by a number: 9/x

4) The sum of nine and a number : 9+x

5) A number divided by 9: x/9

6) Nine less than a number: x-9

7) The product of nine and a number: 9n

G(x)=4x-7<br><br> Find g(-9)<br><br><br> G(x)=x^2-4x+11<br> Find g(-7)
Pie

Answer:

1) -43  2)-10

Step-by-step explanation:

so for the first one you would enter -9 into all of the x's

g(x)=4x-7

g(-9)=4(-9)-7 ( you would get -36, then you would minus y. so the answer is -43!)

g(-9)=-43

second one would be the same thing

g(x)=x^2-4x+11

g(-4)=-7^2-4(-7)+11

g(-4)=-10

How to estimate
monitta
4 3/5 ≈ 5
1 1/5 ≈ 1

(4 3/5) +(1 1/5)
≈ 5 +1
≈ 6 . . . . . . . . . . . the estimated sum rounded to whole numbers

_____
Additional information:
As a refinement to your estimate, you can estimate the error. The first number is 2/5 less than 5. The second number is 1/5 more than 1, so the errors add up to
.. (2/5) +(-1/5) = 1/5

That is, your "estimate" of 6 is actually too high by 1/5. You can refine that estimated value by subtracting 1/5. 5 4/5 would be a closer "estimate."
