CAN SOMEONE PLEASE HELP ME WITH MY MATH CLASS PLEASEEE

13

Step-by-step explanation:

both sides of a diagonal are equal. so, 6x+1=x+11

you then, simplify and get x=2

then, you plug it back in the equation to find EC

13

Step-by-step explanation:

by the definition of a rectangle, we know that AE and EC are equal, so we can write this equation to get x

x+11=6x+1, the first step is to subtract 1 from both sides

x+10=6x, the next step is to subtract 1x from both sides

10=5x, the next step to get x is to divide both sides by 5 to isolate the variable

2=x

Now you have x, you can substitute for x

6(2)+1, which gives you

12+1

If this helped, please consider giving me brainliest, it will help a lot,

Have a good day! :)

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
