Write in slope-intercept form with the given information

ziro4ka [17]

Answer:

y = -2x + 19

Step-by-step explanation:

Firstly, you need to do y = mx + b

Your y is going to be from the given y coordinate (3) , the m will be the slope (-2), and the x will be the from the given x coordinate (-8).

3 = -2(-8) + b Write out equation

3 = -16 + b Simplify

+16 = +16 + b Add 16 to both sides

__________

19 = b Now you have b

y = -2x + 19

-2x is your slope and +19 is your b

Find the volume of a square pyramid with a base area of 18 in.² and a height of 6 in

Ludmilka [50]

ANSWER

36 cubic inches.

EXPLANATION

The volume of a square pyramid is calculated using the formula:

$V = \frac{1}{3} {l}^{2} \times h$

where l² is the area of the base and h= 6 inches is the height of the square pyramid.

We substitute the values into the formula to get,

$V = \frac{1}{3} \times 18 \times 6 \: {in}^{3}$

We simplify to get:

$V = 6 \times 6 =3 6 {in}^{3}$

Therefore the volume of the square pyramid is 36 cubic inches.

Clayton says that 2 1/2 + 3 3/5 will be more than 5 but less than 6 since 2 + 3 is 5. Is Clayton’s reasoning correct? Prove him

antoniya [11.8K]

He is wrong...

2 1/2 + 3 3/5 = 97/20

Simplified, I believe the answer is 4 17/20

The line graph shows the time spent by people visiting the

kari74 [83]

Answer:

Option (B)

Step-by-step explanation:

Average waiting time in the month of October = 20 minutes

Average waiting time in the month of November = 30 minutes

Average waiting time in the month of December = 60 minutes

Average waiting time in the month of January = 40 minutes

Average waiting time in the month of February = 10 minutes

Average waiting time in the month of March = 10 minutes

Average waiting time in the month of April = 30 minutes

Average waiting time in the month of May = 40 minutes

Average waiting time in the month of June = 20 minutes

Total waiting period from October to June = 20 + 30 + 60 + 40 + 10 + 10 + 30 + 40 + 20 = 260

Average waiting period = $\frac{260}{9}$

= 28.89

≈ 29 minutes

Option (B) is the answer.
