Answer:

<u>-7</u>

Step-by-step explanation:

Use slope equation m=y2-y1/x2-x1 aka m=rise/run.

Insert in the correct values.

-1-(-3)=2=run

-8-6=-14=rise

SO, -14/2=m

Simplify:-14/2=-7

<u>m=-7</u>

The slope formula is y2-y1 divided by x2- x1 so -8-6=-14 and -1+3=2
-14/2 =-7

I need help with a problem with solving by square roots in quadratic equation.
Readme [11.4K]

To solve for x, first, we add 3 to the given equation:

\begin{gathered} 2(x+5)^2-3+3=44+3, \\ 2(x+5)^2=47. \end{gathered}

Dividing by 2, we get:

(x+5)^2=\frac{47}{2}.

Therefore:

x+5=\pm\sqrt{\frac{47}{2}}.

Finally, subtracting 5 we get:

x=\pm\sqrt{\frac{47}{2}}-5.

Answer:

x=\operatorname{\pm}\sqrt{\frac{47}{2}}-5.

A bus travels at a constant speed of 48 km/h. How long will it take to travel 600 km?
grigory [225]

Answer:

It will take 12 and 30 hours

Step-by-step explanation:

To solve this, you need to divide by <u>distance needed to travel by the speed</u>

600/48 is equal to 12.5 hours.

.5 hours is equal to 30 mins because 60mins times .5 is 30 minutes, therefore <u>the final answer is 12.5 hours</u>

I hope this helps :)

PLEASE HELP

Answer:

The answer to your question is letter B

Step-by-step explanation:

Process

1.- Find two points of each line

Line A    (-2, 0)   (-1, 2)

Line B    (-1. - 5)   (-6, 0)

2.- Find the slope and equation of each line

Line A

             m = \frac{2 - 0}{-1 + 2}

             m = \frac{2}{1}

                    m = 2

             y - 0 = 2(x + 2)

            y = 2x + 4

Line B

             m = \frac{0 + 5}{-6 + 1}

             m = \frac{5}{-5}

                    m = -1

             y - 0 = -1(x + 6)

             y = -x - 6

3.- Find the inequalities

Line A, we are interesteed in the lower area of the line, so the inequality is

                      y ≤ 2x + 4

Line B, we are also interested in the lower area of the line so the inequality is

                      y ≥ - x - 6

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.
mote1985 [20]

Answer:

You can save 0.40 if you choose to buy the 16-ounce bottles instead of 10-ounce bottles.

0.56x5=2.8

0.40x8=3.2

3.2-2.8= 0.40
