Answer:

They are perpendicular lines

Step-by-step explanation:

If one line has slope -8 and the other one has slope 1/8, they must be perpendicular to each other because the condition for perpendicular lines is that the slope of one must be the "opposite of the reciprocal of the slope of the original line."

the opposite of -8 is 8 , and the reciprocal of this is 1/8

Answer:

Below

Step-by-step explanation:

Let m and m' be the slopes of two different lines.

These lines are peependicular if and only if:

● m×m' = -1

Notice that:

● -8 ×(1/8) = -1

So the lines with the respectives slopes -8 and 1/8 are perpendicular.

2^x-1=128<br><br><br> show work pls! thank u :)
hichkok12 [17]

Hello from MrBillDoesMath!

Answer:

Take you pick below!   (either x 8 or x = 7.01, approx, depending how the question is interpreted)




Discussion:

Interpretation 1

If the question is   2^(x -1)  = 128, then as 2^7 = 128,

x-1 = 7 so x = 8



Interpretation 2

If the question is (2^x -1) = 128, then..

2^x  = 128 + 1 = 129  =>

log(2^x) = log(129) =>

xlog(2) = log(129) =>

x = log (129) / log2 = 7.01

Regards,  

MrB

Answer:

81/16 = 5 1/16

Step-by-step explanation:

-4(square root of x) -3 = -12

Add 3 to both sides

-4(square root of x) = -12 +3 = -9

Divide both sides by -4

(square root of x) = -9/-4

-/- equals +

(square root of x) = 9/4

Square both sides to cancel the square root

x = (9/4)^2 = 81/16 = 5 1/16
