Answer:
x=-2,y=-3
Step-by-step explanation:
x=7+3x
-3x+8y=-18
-21-y=-18
x=7+3x
y=-3
x=7+3x
x=-2
y=-3
40% of her savings = 85
0.40x = 85
x = 85 / 0.40
x = 212.50.....this is her total savings
so after buying the bike for $ 85, she would have (212.50 - 85) = 127.50 <==
Answer:
your answer should look like this.
Step-by-step explanation:
The horizontal line goes through y-intercept -1/2
Answer:
y = mx + b
M is slope, b is y intercept
y = -3x + 5
m = -3
b = 5
The correct answer would be b) d=P-a-b-c
You would take the perimeter and subtract the 3 known sides from it to find the missing side.
