HELP ME ASAP PLEASE!!

x=3

PR=10

Step-by-step explanation:

This is an isosceles triangle, indicated by the black markers on angles P and Q. This also means that sides PR and QR are equal.

That in mind, to solve for x set the two expressions equal to each other and solve for x.

3x+1=5x-5 (subtract 1 from the left side and 5 from the right. Do the same from both sides)

-2x = -6 (divide by -2)

X=3

To find the measurement for PR, simply plug in the value for x into the equation for PR

3(3) +1

9+1 =10

the answer to the question is a  

it has the same slope and the same y-intercept.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
