which equation has a slope of 1/2 and a y-intercept of -5
A. 2x+y= -5
B. 2x-y= 5
C. x+2y= -10
D. x-2y= 10
(not A I chose that one and got it wrong) i will give brainlly

Answers

Answer 1
D because move x over to the other side of the equal sign then you have -2y=-x+10 divide all by -2 that gives you y=1/2x - 5

f(-14) if f(x) = 2x - 3

Answers

Answer:

The correct answer is -31.

Step-by-step explanation:

f(-14) means that x=-14. You have to replace x with -14. Then, you multiply -14 by 2. That is -28. Next you subtract 3 from -28. That gives you -31.

The sum of 4 and seven times a number is 130. What is the number?

Answers

Answer:

18

Step-by-step explanation:

7x+4=130

7x=126

x=18

Answer:

18

Step-by-step explanation:

We can put this into "equation" terms to make it easy for us to solve for the number. Let's assign the "number" the variable x.

The sum of 4 and 7 times a number is 7x + 4. All of this is 130 which means it's equal to 130. So below is how it looks like:  

7x + 4 = 130

7x = 126

x = 18

The number therefore is 18

The ratio of the new perimeter to the old

Answers

Answer:

Step-by-step explanation:

If you multiply each side by 3, you can find out the answer by calculating it. The perimeter of the red figure is 2*L + 2*W = 2*7 + 2*4 = 14 + 8 = 22

Now let's triple the dimensions. The length of the new rectangle is 3*7 = 21

The width = 4*3 = 12

The perimeter = 2*12 + 2 * 21 = 24 + 42 = 66

What's the relationship?

It is 3 times larger so the ratio is 3:1 which is B

Using the box-and-whisker plot given:

a. Range = 9.5

b. The lower 25% of the prices are between $8.75 and $10.5; the middle 50% of the prices are between $10.5 and $14.75; and, the upper 25% of the prices are between $14.75 and $18.25

c. Interquartile range (IQR) = $4.25

What is a Box-and-whisker Plot?

A box-and-whisker plot shows the five number summary which includes:

Lower Quartile (Q1)Minimum ValueMedianUpper Quartile (Q3)Maximum Value, of a data distribution.

Thus:

a. Range = Max - Min

Range = 18.28 - 8.75

Range = 9.5

b. The data distribution in the box-and-whisker plot can be described as:

The lower 25% of the prices are between $8.75 and $10.5

The middle 50% of the prices are between $10.5 and $14.75

The upper 25% of the prices are between $14.75 and $18.25.

c. Interquartile range (IQR) = Q3 - Q1

Interquartile range (IQR) = 14.75 - 10.5

Interquartile range (IQR) = $4.25

y = 20

Step-by-step explanation:

Angles 2 and 4 are vertical angles, so their measures are equal.

m<2 = m<4

62 = 3y + 2

60 = 3y

y = 20

Y=20!

This is because since 2 and 4 are vertical angles they are equal!

62=3y+2

Next subtract 2 from each side

60=3y

And then divide 3 for your answer!
