1. A. parallel, because when you get y by itself it is y=-2x+7, the two equations have the same slope which means they are parallel.

2. B. sometimes, in order for two lines to be parallel they have to have the same slope so, it is possible that two lines say with a slope of 3, those would be parallel BUT it doesn't always have to have a positive slope for it to be parallel like in question 1.

3. C. never, If they have the same slope they are parallel despite whatever the y-intercept is.

Sandra is 4 feet tall. Pablo is 10% taller than Sandra and Michaels is 8% taller than Pablo. What is Michael height in feet

taurus [48]

We first calculate Pablo's height .

4 = 100%

x = 1% (Where x is 1% of Sandra's height.)

cross multiplying the equation, we get:

100x = 4 → x = 4/100 → x = 0.04

If 1% = 0.04, then 10% will be 0.04 × 10 = 0.4

Pablo's height is 4 + 0.4 = 4.4 feet.

Now we repeat the above steps to get Michal's height from Pablo's height

4.4 = 100%

x = 1% so:

100x = 4.4 → x = 4.4/ 100 → x = 0.044

If 1% = 0.044, then 8% will be 0.044 × 8 = 0.35

Michael's height is 4.4 + 0.35 = 4.75 feet.

If $500 is deposited in a savings account providing an annual interest rate 5.6% compounded quarterly, how long will it take for

Sidana [21]

Answer:it will take 5 years

Step-by-step explanation:

Initial amount deposited into the account is $500 This means that the principal is

P = 500

It was compounded quarterly. This means that it was compounded 4 times in a year. So

n = 1

The rate at which the principal was compounded is 5.6%. So

r = 5.6/100 = 0.056

The formula for compound interest is

A = P(1+r/n)^nt

A = total amount in the account at the end of t years. A is already given as $750

Therefore,

750 = 500 (1+0.056/4)^4×t

750 = 500 (1+0.014)^4t

750 = 500 (1.014)^4t

(1.014)^4t = 750/500 = 1.5

Take root 1/4 of both sides

(1.014)^4t ×1/4 = 1.5^1/4

(1.014)^t = 1.107

t = 5 years
