Answer:
the y intercept is 4
Step-by-step explanation:
f(x)=4-5x
rewrite
y = -5x+4
this is in the form y= mx+b where b is the y intercept
b = 4
Answer:18
Step-by-step explanation: pluging in -b/2a for first equation you get 3 plunging 3 in you get 6 solving for second equation you get -x^2+6x+3 pluging in -b/2a you get 3 then plugoing into equation you get 12 12-(-6)=18
3x+2y=5
2x+2y=0
The solutions are: x=5, y=-5
X = y + 10
x = 2y + 3
sub 1 x in for the other
y + 10 = 2y + 3
10 - 3 = 2y - y
7 = y
x = y + 10
x = 7 + 10
x = 17
ur solution is (17,7)
