Answer 37, 38, and 39 and make sure to answer with either the letter or with one of the answers shown! SHOW YOUR WORK PLEASE!!

ollegr [7]

Answer:

I didn't even realize until I had written all of the answers down that they are all C.

37 = C. 15%

38 = C. 2 $x^{3}$

39 = C. 48

Step-by-step explanation:

37: I used process of elimination to figure out which percentage of decrease it was by just multiplying 42 by each percentage until I got 6.3 which is what you need to subtract from 42 to get 35.7, so the answer is C, or 15%.

38: A coefficient is the number that is being multiplied by the variable, which in this case is "x". So whatever answer involves "2x" is the correct answer. Therefore the answer is C, or 2 $x^{3}$ .

39: You have to add the amount of money Henry paid for painting supplies and how much profit he mad to figure out how much money he really made. 400 + 560 = 960 and he charges $20 for each painting so you need to divide 960/20 to get your answer, which is C, or 48.

Find the slope and y-intercept for this table.

labwork [276]

Answer:

See below:

Step-by-step explanation:

To find the slope, we use the following formula:

$\frac{y_{2} - y_{1} }{x_{2} - x_{1} }$

For this case, we can use (6,60) as the first set of points.

We can use (4,70) as the second set of points.

Now, we can use the formula, 70-60 is for the top of the fraction (10)

We can do 4-6 to find the bottom, which is (-2)

Now, if we add the fraction back we get -> 10/-2 which is -5 for slope!

To find out the y intercept, it in simple words is "What is y when x is 0?".

We can do that by using the slope intercept formula: $y=mx+b$ .

Once we insert our slope which is -2 we get: $y=-2x+b$

We can now substitute a point, lets use (6,60) so we can find out b.

We now get the equation: $60=-5(6)+b$ .

If we solve for that we get 90!

Once we input that, we get, $y=-5x+90$

Now we put in x as 0 and we get our y intercept as 90!

Translate this sentence into an equation. 48 is the product of Greg’s score and 3. Use the variable g to represent Greg’s score

ratelena [41]

Answer:

G x 3 = 48

Step-by-step explanation:

let G be Greg's score

And product means multiplication.

so G x 3 = 48.

finding Greg's score means 3g = 48.

g = 48/3

g = 16.
