Alejandro made an error in the steps below when determining the equation of the line that is perpendicular to line 4x - 3y = 8 a
Ronch [10]

 

Hello:<span>
the equation is : y = ax+b
the slope is a : a×(4/3) = -1......( perpendicular to a line with a slope of   4/3)            because :     4x-3y =8...y=(4/3)x-8/3    )     </span>

<span>
a = -3/4         y=(-3/4)x+b
the line that passes through (3, -2) :- 2 = (-3/4)(3)+b
b =1/4
<span> the equation is :  y  = (-3/4)x+1/4</span></span>

Determine whether 81 − 49n4 is a difference of two squares. If so, factor it. If not, explain why.
Mumz [18]

We have

81-49n^4=9^2-(7n^2)^2

so this is indeed a difference of squares. Factorizing would give

81-49n^4=(9-7n^2)(9+7n^2)

making the answer D.

We can further factor the first term here and write

9-7n^2=3^2-(\sqrt 7\,n)^2=(3-\sqrt7\,n)(3+\sqrt7\,n)

but that's clearly out of the scope of this question.

Can somebody plz help answer all the questions correctly thanks a lot !!!
Lady_Fox [76]

Answer:

7. 250%

8. 400%

9. 667%

10. 769%

11. 263%

12. 125%

13. 137%

14. 526%

Step-by-step explanation:

divide the first number by the second number, then multiply that answer by 100

so kind of like: Number1 ÷ Number2 = x

then you do x × 100

and that's your answer

(all of my answers are rounded to the nearest percent)
