Answer:
Slope is -4
Y-intercept is -3 or (0, -3)
Step-by-step explanation:
y= mx + b
m = slope
b = y-intercept
12x + 3y = -9
3y = -12x - 9
y = -4x - 3
Answer:
1 apple= $0.4
Step-by-step explanation:
Let o=orange
Let a=apple
4o+5a=4
2o+3a=2.20
2o=2.20-3a
o=2.20-3a/2
Let's go balk to the the first equation
4o+5a=4
4(2.20-3a/2)+5a=4
4.4-6a+5a=4
4.4-a=4
-a=-0.4
a=0.4
Apple=$0.4
A and C are equivalent expressions.
