Answer:
Maybe 74
Step-by-step explanation:
42+64=106
180-106=74
Answer:
Greek
Step-by-step explanation:
compare 5/7 and 64/89
5/7 = .71429
64/89= .71910
64/89 is the greater fraction
Solve by substitution. We begin by manipulating the second equation (solving for y).
2x+3y=13
4x-y=-2 => -y=-4x-2 => y=4x+2
Now substitute "4x+2" for y into the first equation because y=4x+2.
2x+3y=13 becomes 2x+3(4x+2)=13
Now solve for x.
2x+3(4x+2)=13
2x+12x+6=13
14x=7
x=1/2
Now we can solve for y because we know what x is.
y=4x+2 => y=4(1/2)+2 = y=4
answer: x=1/2, y=4, intersection point (1/2,4)
Answer:
y = mx + c
m = -4
at y intercept x = 0
(x,y) =(0,-3)
-3 = -4(0) + c
c = -3
therefore the answer is y = -4x + c
