What is the equation of the line that passes through the point (8,-4) and has a slope of 3?

Answers

In order to solve it you insert the point in slope from

the equation is
Y=Mx+b

Plug it in as

-4=3(8)+b


-4=24+b

Then subtract 24

B=-28

So

The answer is

Y=3x-28
y-y1=m(x-x1)

(8, -4) 8 is x1 and -4 is y1
so y- (-4) = 3 (x -8)
make 4 a positive then y + 4 = 3x - 24
subtract 4 from 24 then y=3x-20

select the correct expression.

Answers

Answer:

D

Step-by-step explanation:

All we need to know is that there are 2 PASTRIES, this makes it to where we can exclude any equation multiplying against two tea cups. Thus making D the only answer correct.

D

because she wants to buy 2 pastries and one costs $2.75, so you’ll need to multiply by two. the tea is not needing to be multiplied. this expression is a y = mx + b.

Does the equation have one solution, no solutions, or all solutions? 7x + 4 = 9(x-1)

Answers

One solution
Explanation:
First you remove the parenthesis
28=9x-9
Then you calculate
-9x = -9 - 28
Then you divide both sides
-9x = -37
Solution: 37/9
Alternative form:
4 1/9 or 4.1
Note: these are all the same solutions, they are just in different forms

HELP ASAP!! GIVING BRAINLIEST

Answers

Answer:

the answer is B

Step-by-step explanation:

hope this helps you!

Answer:

B

Step-by-step explanation:

You see that the question mentions MPH. An hour is 60 minutes, so you would look at the 60 minutes on the base of the graph. If you go directly up to where the diagonal (dark) line perfectly crosses a point of the grid (that's any corner of any square on this grid) and look directly to the left (which represents the MPH) you see the number 3. If you go even higher, you see 6 MPH.

The 3 miles at 60 minutes represents 3 MPH, which is Tanisha's speed.

The 6 miles at 60 represents 6 MPH, which must be Albert's speed.

Since 6 is two times bigger than 3, the correct answer is B) Albert is running two times faster than Tanisha is walking.

1. 11, 15, 19, 23
2. Above, Below

Answers

Answer:

Step-by-step explanation:

theres nothing to do. just do it right how the question is given. so yeah

1. 23
2. Below

This is because if you do -51 / 3, you do this because you do not have any starting position. That gets -17 feet under the ocean but this is the fishes position so you need to subtract 6, not add because the diver is below the fish and that would get you -23 absolute value that you get 23 and it is below because they are in the water.

Of your problem as like if you went to a store and so clothes were 34 percent off you going to get the original percent and then your doing 450\x ok now I go over 34%\100 it’s always going to be one hundred but since we’re talking about something else here’s your answer your just gonna say the ratio in this problem and your going to use that calculator call Dezmos use the scientific one and it will give you the answer if put 450 then 34%
If you put 34% over 100 multiply 34 and 450 then you will have 15,300. Then divide 15,300 and 100.

Jose goes out to lunch. The bill, before tax and tip, was $10.45. A sales tax of 8% was added on. Jose tipped 17% on the amount after the sales tax was added. What was the total cost of the meal, plus tax and tip? Round to the nearest cent.

Answers

$13.20 $10.45x1.08=$11.28 $11.28x1.17=$13.20
ANSWER: $13.21

Find 8% of 10.45 then add the answer to 10.45 to get how much it cost after the sales tax.

8% of 10.45 = 0.836

Add 0.84 to 10.45

The answer is 11.29

Now take 17% of 11.29 and add it to 11.29. We are taking 17% of 11.29 because it said he tipped after the sales tax was added.

17% of 11.29 = 1.92

11.29 + 1.92 = 13.21
