Which is the slope of a line that is perpendicular to the line represented by the equation x-y = 8
Marat540 [252]

Answer:

-1

Step-by-step explanation:   from the equation,  x-y=8,  make  y the subject of the formulae , this gives - y=  -x +8

divide all through by (-) sign, this gives   y= x - 8

from the last equation above, the slope is the coefficient of x which is 1. since it is perpendicula, the answer is -1

HELP 99 PTS=50 PTS Theresa has two brothers, Paul and Steve, who are both the same height. Paul says he is inches shorter than t
iren [92.7K]

Answer:

Theresa is 58.82 in tall

Step-by-step explanation:

Let 

x----------> Paul and Steve heights

y----------> Theresa height


we know that

1 1/2-------> 3/2---> 1.5

1 1/3-------> 4/3----> 1.33

 Paul says he is 16 inches shorter than 1 1/2 times Theresa's height

x=1.5y-16-------> equation 1


Steve says he's 6 inches shorter than 1 1/3 times Theresa's height

x=1.33y-6------> equation 2


equals 1 and 2

1.5y-16=1.33y-6

1.5y-1.33y=-6+16

0.17y=10----------> y=58.82 in


x=1.5y-16------> 1.5*(58.82)-16------> x=72.24 in


the answer is

Theresa is 58.82 in tall

Which statements about the graph of f(x) =√x are true?
marshall27 [118]

Answer:

Step-by-step explanation:

So let's think about what values you can take square root of...

anything but negative values!

So the first one is not correct because you can also take square root of 0,

squareroot of 0 is 0.

So because of this, C and D are both correct, E is correct because root  x is an increasing function. B is incorrect because (0,0) is an intercept.
