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.

Need Help Please <br><br> what is y <br><br> 2x-4y=58?
Bond [772]

Answer:

y = 1/2 x -14.5

Step-by-step explanation:

2x-4y=58

solve for y

subtract 2x from each side

2x-2x-4y = -2x+58

-4y = -2x+58

divide by -4 on both sides

-4y/-4 = -2x/-4 +58/-4

y = 1/2 x -14.5

shusha [124]

Answer: He would have 16590 but if we want to know in total

it would be, 11060 (just from the percent) if you want to know in total add 16590 and 79,000 which would be (95,590 for Landon) and (Elijah would be 90060) in total

Step-by-step explanation:So in total Landon would have:

Landon-(95,590)

Elijah-(90,060)

So Landon would have 5,530 more dollars in 7 years than Elijah.

A student say that the x-intercept of the graph x + 2y=5 is the point (0,5). Why is the student incorrect?
harina [27]

Answer:

the x-intercept is found when 0 is put into the equation for y.  

Because the x-intercept is found when the function passes through the x-axis.

x+2y=5

x=5

So x=5, y=0, the point would be (5,0).
