ANSWER

Step 1

EXPLANATION

The given polynomials are:

( {k}^{2}  + 2k - 13) - ( - 3 { k}^{2}  + 9k + 1)

Annie's expansion should have been,

{k}^{2}  + 2k - 13+ 3 { k}^{2}   -  9k  - 1

But she got:

{k}^{2}  + 2k - 13 + 3 { k}^{2}  + 9k + 1

Therefore Annie made an error in the first step.

Algebra!!!<br> 3 Questions Only take if you know ALL Answers<br> PLZZZ QUICK
vitfil [10]

Answer:

1. -7.5

2. $1

3. 40

Step-by-step explanation:

For number 1, it can be solved by using the PEMDAS method, or see explanation below:

6x - 4x - 36 = 6 - 2x

2x - 36= -2x + 6

4x + 36 = 6

4x = -30

x = -15/2 or -7.5

For number 2, substitute 3 into both equations:

f(x) =1.50(3) + 2.00

and

f(x) = 2.00(3) + 1.50

This would get $6.50 and $7.50, which, if subtracted, gets $1.

For number 3, do something similar to the previous problem. Substitute 3 for x. It would be 5(2^3), or 40.

Hope this helps!

Which integer is closest to 0 on the number line?
IrinaVladis [17]

An integer is close to zero if it is "small".

By small, we mean that it is small in absolute value. In fact, for any given distance d, there are two integers that are d units away from zero: d and -d.

So, for example, -6 is close to zero than 8, because -6 is six units away from zero, while 8 is eight units away from zero.

So, the answer is B, -8, because it is 8 units away from zero. The other options A, C and D are, respectively, 12, 10 and 14 units away from zero.
