Answer:
The answer to your question is x = 30; y = 14
Step-by-step explanation:
Data
JK = x PR = 20
JL = 21 PQ = y
LK = 18 QR = 12
Process
1.- Find x
Use proportions to find it
JK/PR = LK/QR
Substitution
x/20 = 18/12
Solve for x
x = 20(18/12)
x = 360/12
x = 30
2.- Find y
PQ/JL = PR/JK
Substitution
y/21 = 20/30
Solve for y
y = 21(20/30)
y = 420/30
y = 14
This is a fairly easy problem, actually. Take all your options and do the equation (which is 2(x+2)-17) until it gets to 35. I recommend you use a calculator, but you can do it on paper if you need to. If you don't have answer options, I'm happy to work it out with you !
For perpendicular lines m2 = -1/m1, i.e. the product of the two slopes equals -1.
x - 5y = 3
5y = x + 3
y = 1/5 x + 3/5 => slope = 1/5
m2 = -1/(1/5) = -5
Equation of a line containing point (-4, 6) with a slope of -5 is
y - 6 = -5(x - (-4))
y - 6 = -5(x + 4)
y - 6 = -5x - 20
5x + y = -20 + 6
5x + y = -14
The answer is x = 10/3. You just have to add 21 to both sides of this equation then simplify. Hope this helped!
Add 6 to both sides so you have -2x = 18. If you divide both sides by -2 you will get x = -9
