I think what you need to do is make B = -5
3a = -2(-5) - 7
3a = 10 - 7
3a = 3
a = 1
Answer:
Step-by-step explanation:
You would substitute "2x" for every "x" in the function in the same way you would substitute any other number.
So if f(x)=Sqrt[7x²-3x], then: f(2x)=Sqrt[7(2x)²-3(2x)]
=Sqrt[7(4x²)-3(2x)]
=Sqrt[28x²-6x]
Answer:
8.5
Step-by-step explanation:
1.7*5=8.5
200R + 475P = 7700
200(19) + 475(9) = 7700
3,800 + 4,275 = 7700
8075 = 7700 IS NOT EQUAL So Yes It Will Overload The Truck.
