Frank bought 791 acres of land for a housing development. If 41 acres of his purchase is reserved for a park, how many five-acre
GalinKa [24]

To solve the question, first we will subtract 41 from 791, and we will get 750. Next, we can divide by 5 to figure out how many lots are for purchase, and we get 150! There are 150 five-acre lots available!

What is the slope of a line that is perpendicular to y=1/2x+9 that passes through (-7,-4)
Artist 52 [7]
Hi there!

To find the perpendicular slope you need to flip the fraction and change the sign. So 1/2=2/1 and tge original slope was positive, so the slope is -2. Now you sub in the point (-7,-4) in for x and y in the formula y=mx+b and solve for b (sub in 2 for m as well)
Y=mx+b
-4=-2*-7+b
-4=14+b
-4-14=b
B=-18
The equation is y=-2x-18

Hope this helps!

Damian is buying a video game that was just marked 20% off. The original price was
JulsSmile [24]
Answer: $64

80(0.20) = 16
80 - 16 = 64

Since it’s a discount, after we multiplied it with 20% (0.20), we need to take the product and subtract it from the original price.

Please help me and my son I am confused
Agata [3.3K]

Answer:

-13p^{4} - 8p^{2} + 4p + 3

Step-by-step explanation:

I am having a little trouble reading the number.  I think 5 is the question number and not part of the problem.  I think this is the problem:

(4p - 6p^{4} - 3) - (8p^{2} + 7p^{4} - 6)  You take the opposite of everything inside the second set of parentheses.  You can think of it as multiplying through by -1

4p - 6p^{4} - 3 - 8p^{2} - 7p^{4} + 6  Now we combine like terms.  That is the numbers with the same variable p and the same power of p.

-13p^{4} - 8p^{2} + 4p + 3
