Answer:
x= - 3.5
y= - 6.5
Step-by-step explanation:
-3x+y = 4 equation 1
-9x + 5y = -1 equation 2
and
equation 1 can be written as
y = 4+ 3x
so put this in equation 2
-9x + 5 ( 4+ 3x) = -1
-9x +20 +15x = -1
6x = -21
X= -21 ÷ 6
X = - 3.5
so put this value of x in equation 1 to find value of y
-3 ( -3.5) + y = 4
10.5 + y = 4
y = 4 - 10.5
Y = - 6.5
multiply 675 by 0.25 to find 25% of 675. the answer would be 168.75
hope this helps!
Answer:
The answer is y=-3/5x-6
Step-by-step explanation:
y-y=m(x-x1)
y-(-3)=-3/5(x-(-5))
y+3=-3/5x-3
-3 -3
y=-3/5x-6
Answer:
(0,-4) (-8,0)
Step-by-step explanation:
x = 0, y = -4
y=0, x = -8
