Answer:

The y-intercept is 7

Step-by-step explanation:

To find either the x-intercept or the y-intercept of an equation, all you have to do is substitute 0 for the other variable.

So to find the y-int, just plug 0 in for x, and vice versa

y = -5x+7

y = -5(0)+7

y = 0+7

y= 7

Principal Amount = P = $7200
Interest rate = r = 4% = 0.04
Time = t = 8 years

Formula for compounding is:

$A=P (1+r)^{t}$

Using the values, we get:

$A=7200 (1+0.04)^{8}=9853.70$

Therefore, the compounded amount will be $9853.70

4)
Principal Amount = P = $7200
Compounded Amount = A = $9853.70

Interest Earned = Compounded Amount - Principal Amount
So,
Interest Earned = 9853.70 - 7200 = $2653.70

Therefore, $2653.70 will be earned as interest over a period of 8 years.

Andrei [34K]

8/(2-√ 12) Both sides multiplied by (2+√ 12)

16+8√ 12/4-12

-(16+8√ 12)/8

The new denominator is 8 and the fraction has a negative sign

On the playground, 1/4 of the students are on the jungle gym, and 1/3 f the students are playing kickball. What part of all the

marshall27 [118]

Answer:

7/12 of the students

Step-by-step explanation:

So first you would need to get your fractions to have the same denominator. When your trying to get your fractions to get the same denominato. You must multiply both the numerator and denominator.

The most common denominator from 1/4 and 1/3 is 12. So you multiply both the numerator and denominator of 1/4 by 3. So then your new fraction is 3/12. Now you multiply 1/3, both numerator and your denominator by 4. Then your new fraction is 4/12. So The last step is to add both of your numerators. Never add the denominators together. And at last you have your answer. 7/12.
