Answer:

the y-intercept is 7

Step-by-step explanation:

hope it helps. i just looked at the ordered pair and took the number that's on the y axis

Answer:

y=5x-3

Step-by-step explanation:

Slope intercept form is y=mx+b and you know the slope so you can get y=5x+b

Then you are given a point, (2, 7), so you can plug that into the equation to find the y-intercept

7=5(2)+b

Then you just solve for b

7=10+b

-10

-3=b

So the final equation is y=5x-3

What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

We have,

Red marble= 3

Yellow marble = 2

Blue marble = 1

So, the percent of change of choosing yellow marble

= 2/6 x 100

= 33.33%

2. The likelihood of a yellow marble being selected on the first draw is likely.

3. The probability of a yellow marble being selected on the first draw

= 2/6

=1/3

4. The odds of a yellow marble being selected on the first draw

= 2:4

7. An equation is shown. x + 5 = 14 Which of the values can be substituted for x to make the equation true?

Answers

Answer:

9 can be added to make equation true i .e 14=14

hope it helps.

Answer:

B.

Step-by-step explanation:

When you plug in 9 for this equation, you have 9 + 5 = 14, which is true.

If you plug in 7, you would have 7 + 5 = 14, which is actually 12. So, this is incorrect.

If you plug in 14, you would have 14 + 5 = 14, which is actually 19. So, this is incorrect.

If you plug in 19, you would have 19 + 5 = 14, which is actually 24. So, this is incorrect.

That leaves you with B.

Hope this helps! :)

choose yes or no to tell if the fraction 2/9 will make each equation true
81 x =18
900 x = 200
72 x =16
450x = 100

Answers

Answer:

yes

Step-by-step explanation:

to see if 2/9 will make each equation true, you replace 'x' with 2/9, so let us do just that-

81*2/9=18

900*2/9=200

72*2/9=16

72*2/9=16

450*2/9=100

now, seeing as how every answer we've gotten matches the answers of the algebraic equations, the answer is yes 2/9 does make each equation true

good luck :)
