Answer:
-4
Step-by-step explanation:
5 x(-4) = -20
50 - 20 = 35
Answer:
x = 5, y = -1/2
Step-by-step explanation:
3.5x - 5y = 20
3x + 4y = 13 multiply by 1.25 so the y's match up (you could match x's too)
3.75x + 5y = 16.25
–––––––––––––––––––––––
3.5x - 5y = 20
3.75x +5y = 16.25
7.25x + 0y = 36.25 you can add or subtract here (on this equation you add)
7.25x=36.25
x=5 So now we have x=5 and to find y we can just plug in x into one of the equations
–––––––––––––––––––
3(5) + 4y = 13
15 + 4y = 13
4y = -2
y = -1/2
x = 5, y = -1/2
Then you can plug in both to check your answers.

Hoped this helps.
Mya took out money from the bank. When she went to get a bank statement she saw she had a $-2.00 in her account but she needed the number so she took out $30. So you would do $30+(-2.00)=(-32.00)
Answer:
y=x-3
Step-by-step explanation:
slope=4+2/-5-1=-1
perpendicular slope= negative reciprical=1
y=x+b
midpoint on perpendicular bisector= (-5+1/2, 4-2/2)=(-2,1)
substitution-2=1+b, b=-3
y=x-3
