Answer:
1
Step-by-step explanation:
slope must be same because it is paralel
X/3 +10=15
-10 -10
x/3 =5
so the x will be 15 because if you multiply 3x5 = 15
-2x^2(4x − 3)
=-8x^3 + 6x^2
hope it helps
The slope is 3 and y-intercept is 4
y=mx+b
By definition of percentages, we conclude that Montraie has 10 coins saved in his box that come from a collection with a total of 50 coins.
