Find the equation of the line that contains the points (-5, 0) and (-3, 4)

Answers

Answer:

y = -1/2x - 5/2

Step-by-step explanation:

With points (-5,0) and (-3,4), we need to find the slope first.

[Find slope of points]

Using slope formula m = (Y2 - Y1) / (X2 - X1)

Using points: m = (4 - 0) / (-3 - 5) = 4/-8 = -1/2

[Use point-slope formula]

(y-y0) = m(x-x0)

Using points: (y - 0) = -1/2(x - -5)

Finally: y = -1/2x -5/2

Question 6 (ID=27678)
As labor costs, an electrician charges $36.50 per hour for himself, and $27.50 for his assistant. What would be the total labor cost for a job taking 6 1 over 2 hours?

A: $416.00 Strike Reset
B: $384.00 Strike Reset
C: $264.75 Strike Reset
D: $64.00 Strike Reset

PLEASEE

Answers

Answer:

36.50 + 27.50= 64 64 X 2= 128

Step-by-step explanation:

but i don't understand what you mean by taking 6 1

36.50+27.50=64, so multiply it by 2 and it will be $128 in total for two hrs

Which of the following situations will include the origin when graphed?

A. Hayley runs at a pace of 1 mile every 8 minutes.
B. Gas costs $3.50 per gallon.

D. Phone service costs $5.00, and an additional 5 cents for each minute.

You can choose more than one answer.....

Answers

I'd say A, D, and B.

However, I would choose answers at a CONSTANT because, what if you need to divide or multiply or something, let's say Derek runs 5 miles per 1 hour, you'd have to divide. Yet, I recommend these three answers.

Answer: A. Hayley runs at a pace of 1 mile every 8 minutes.

B. Gas costs $3.50 per gallon.

download an aoo call desmos it helps alot with stuff like this

Well since we know that its length and width is 8 and 10, and the perimeter is 36, we multiply those to get the diameter of the circle, then we use the formula r = d/2. Then that should get you the radius.

y+16= -8
Another Question heheh

Answers

Answer:

y = -24

(mark me brainliest)

y=-24
To solve this you need to get y by itself so you have to move 16 to the other side. To do this you are doing to do the opposite of what it says so since on that side it’s addition you are going to subtract. Subtract 16 from 16 which cancels it out, then subtract 16 from -8 to get -24. Now you have y=-24

The ratio of keepers to animals in the city zoo is 2 : 7. 12 keepers and 42 animals. If 21 more animals are added, how many total keepers are needed to maintain the ratio of keepers to animals?

A. 16

B. 17

C. 18

D. 19

E. 20

Answers

Answer:

C: 18

Step-by-step explanation:

All you have to do is write down the ratio. Then you find out that 21 is half of 42 so that means that the amount of zookeepers that you will have to add should be half the amount as well so instead of 12 it would be 6. Then you just add the two numbers together to get your final answer of 18.

The answer is 18 keepers
