Answer:
it would take 40 pounds of pressure to break the board.
Step-by-step explanation:

Now we plug in the numbers of force and length

Now we multiply both sides by 2.5 to get rid of the fraction.

Now we plug in our variation constant

So we convert the length of 2.5 feet into inches. This is 18 inches. Since there are 12 inches in one foot, we have that 18 inches is equal to 18 divided by 12.
18÷12=1.5
We get that 18 inches is equal to 1.5 feet
we plug L = 1.5 into our inverse variation equation and solve for F.

This simplifies to F = 40

C is the answer. 784.5 + 6.5%(784.5) = 835.49
Answer:
y=-3-3x
Step-by-step explanation:
Transpose the equation for y
y=-12/4-12x/4
y=-3-3x
When two polynomials are multiplied, each term of the first polynomial is multiplied by each term of the second polynomial. ... The result is always a polynomial, regardless what the coefficients might be of any of the terms, including the leading coefficients.
