x−y=−8 in slope intercept form

Answers

Answer:

-y=-x+-8

Step-by-step explanation:

Answer:

y = x + 8

Step-by-step explanation:

Slope-intercept form looks like y = mx + b.

We have X−y=−8 and need to solve this for y:

Change all signs, obtaining -x + y = 8

Add x to both sides, obtaining  y = x + 8

Felice swims 3 times every 7 days.
How many times will she
swim in 28 days?

Answers

Answer:

12 times.

Step-by-step explanation:

If she swims three times a week, then you need to find how many weeks make up 28 days. 28/7= 4 weeks. Since she swims three times a week, you multiple that by the amount of weeks, which is four. You get that she swims 12 times in 28 days.

Sal made 8 ft of sausage links on Friday morning. He used 4 ft for dinner service on Friday night. On Saturday morning, he made another 8 ft of sausage links and used 12 ft for dinner service Saturday night. What is the net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night?

Answers

Answer:

Net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night = 8 - 0 = 8 ft

Step-by-step explanation:

Amount of  sausage links made on Friday morning = 8 ft

Amount of  sausage links used on Friday night = 4 ft

Amount of  sausage links remaining = 8 - 4 = 4ft           (i)

Amount of  sausage links made on Saturday morning = 8 ft         (ii)

So,

Total amount of  sausage links = 8 + 4 = 12 ft   (from (i) and (ii) )

Amount of  sausage links used on Saturday night = 12 ft

Amount of sausage links remaining = 12 - 12 = 0 ft

Net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night = 8 - 0 = 8 ft

The following figures are not drawn to scale but AB and CD are straight lines. Find x.

Answers

Answer:

uh I think x=25°

Step-by-step explanation:

2x+60°=110°(vertically opposite angles are equal)

2x=110°-60°

2x=50°

x=50°÷2

x=25°

A straight line equals 180 so O =70 and so does the angle across from it to add the knowing angles and you’ll get 310. Subtract this from 360 since that is the degree of a circle and get 50. So then your equation is 50= 2x and you divide and get x=25

Keiko has a 20% copays for hospital visits after paying her deductible. Assuming she already paid her deductible earlier in the year, how much will she pay (copay) for a hospital bill of $3,291?

A. $328.90
B. $658.20
C. $2,632.80
D. $1,645.50​

Answers

Answer:

$658.20

Step-by-step explanation:

Money paid in deductible = $3,291

percentage of money to be co-paid = 20% of Money paid in deductible

Thus, she has to 20 percent more which will be 20/100 th part of money paid in deductible.

Solving it we have

Money to be co-paid =  20% of $3,291 = 20/100 * $3,291 =  $658.20

Thus, Keiko will  pay (copay) $658.20 for the hospital bill

What is an equation of the line that passes through the point (8,2) and is parallel to the line x+4y=28

Answers

Answer:

y = -1/4x + 4

Step-by-step explanation:

x+4y=28

4y = -x + 28

y = -1/4x + 7

slope m = -1/4

Parallel lines have similar slope so we'll use -1/4 from above and given point (8,2) to find y-intercept.

y = mx +b

2 = -1/4(8) + b

2 = -2 + b

b = 4

Using m and b from above we can now form the new equation of line that is parallel to y = -1/4x + 7.

y = mx + b

y = -1/4x + 4

Answers

Answer:

the answer is C, 0

Answer:

C) 0

Step-by-step explanation:

7(x + 2) = 7x - 10

First, we multiply within the parenthesis

7x + 2 = 7x - 10

Add 10 to both sides of the equation

7x + 12 = 7x

Subtract 7x from both sides of the equation

12 = 0

Because the answer is 0, that means there are 0 solutions and the equation can not be solved.

I hope that this helps! :)
