Answer:
B) 
.
Step-by-step explanation:
The vertex form of the equation is given by 
.
We plug in the vertex to obtain:
.
Since the graph passes through (5,5) and (9,5), they must satisfy its equation.
.
.
Divide both sides by 4.
Therefore the equation is:
.
I = PRT is the formula for interest, and we need to solve it for R. Since all three of P, R, and T are multiplied, we send things to the other side of the equals through dividing.
I = PRT
I / P = RT to divide both sides by P
I / PT = R to divide both sides by T
So I / PT = R (the first choice) is the equation solved for R.
Answer:
The equation of the line would be y = 3x - 10
Step-by-step explanation:
To find the equation we first need to note that parallel lines have the same slope. So since the original equation has a slope of 3, the new one will as well. Now we can use that slope and the given point in point-slope form to find the equation.
y - y1 = m(x - x1)
y + 4 = 3(x - 2)
y + 4 = 3x - 6
y = 3x - 10
Remember PEMDAS
Do parentheses, results in 25. So whats left is 87-25*(-3)+9
Then you multiply -25 by -3, answer is 75. 87+75+9
Add all of them up. 171
The answer is 171!
The strip of wood would only be able to be cut in to 12 strips
