N^2+7n+15=5
show work please

Answers

Answer 1
Answer: n^2+7n+15=5
n^2 + 7n + 10 = 0
(n + 5)(n + 2) = 0
n + 5 = 0
n = -5
n + 2 = 0
n = -2

Answer: n = -5 and -2
Answer 2
Answer: n^2+7n+15=5

n^2+7n=-10

n^2+7n+((7)/(2))^2=-10+((7)/(2))^2

n^2+7n+(49)/(4)=-10+(49)/(4)

(n+(7)/(2))^2=(9)/(4)

n+(7)/(2)=\sqrt{(9)/(4)}

n=-(7)/(2)+\sqrt{(9)/(4)}

n=-2
n=-5

If you know the rate of a water leak in gallons per hour, how can you find the number of hours it takes for 1 gallon to leak out?

Answers

You will need to take the rate it's leaking out at, and figure out how many times that unit goes into one full gallon. Then you will need to multiply your answer by the time given in the rate.

.5 gallon goes into 1 full gallon twice. And 2 x 2 = 4

So figure it out.
You will need to take the rate it's leaking out at, and figure out how many times that unit goes into one full gallon. Then you will need to multiply your answer by the time given in the rate.

Example: If the rate is .5 gallon per 1 hour, then we already know that it will take 2 hours...but to calculate it, we will take the .5 gallon and see how many times it goes into a full gallon, Its 2. Now multiply by 1 (since the rate was .5 gallon per 1 hour). So the answer is in fact 2.

Example 2: If the rate was .5 gallon every 2 hours, we will use the same method. If we think about it, we probably already know it will be 4 hours...but lets calculate!

.5 gallon goes into 1 full gallon twice. And 2 x 2 = 4

Estimate the sum of 502 and 47 by rounding both values to the nearest ten. What is the best estimate of the sum?

Answers

Nearest tenth of 502 is = 500
Nearest tenth of 47 = 50

So, the sum is = 500 + 50 = 550

In short, Your Answer would be 550

Hope this helps!
 my best estimate would be 550

What is the slope of a line that passes through the points (2, 0) and (5, 0)? Explain.incorrect answer: 0; The change in \(x\) is 0 because the x-values do not change. So, the slope is 0.

a) 0; The change in y is 0 because the y-values do not change. So, the slope is 0.

b) undefined; The change in x is 0 because the x-values do not change. So, the slope is undefined.

c) undefined; The change in y is 0 because the y-values do not change. So, the slope is undefined.

d) 2/5; To find slope, divide the x-value of the first point by the x-value of the second point. So, the slope is 2/5.

e) 5/2; To find slope, divide the x-value of the second point by the x-value of the first point. So, the slope is 5/2.

Answers

it is 0, the change in y is 0 , the slope is zero!
