3x + 8y = 14 find the x and y intercepts of each function
olganol [36]

The y intercept is found by  putting x = 0 and calculating y,  and vice versa.

y intercept:-

3(0) + 8y = 14 ;  8y =14;  so y = 14/8  = 7/4

x intercept:-

3x + 8(0) = 14 ; 3x = 14; x = 14/3

Your parents will retire in 19 years. They currently have $350,000 saved, and they think they will need $800,000 at retirement.
patriot [66]

Answer:

<em>The annual interest is 6.77%</em>

Step-by-step explanation:

<u>Simple Interest</u>

Definition: Interest calculated on the original principal only of a loan or on the balance of an account.

Unlike compound interest where the interest earned in the compounding periods is added to form the new principal, simple interest only considers the principal to calculate the interest in every period.

The interest earned is calculated as follows:

I=Prt

Where:

I = Interest

P = initial principal balance

r = interest rate

t = time

Your parents will retire in t = 19 years. They have P=$350,000 in their savings account and they need to have $800,000 when they retire.

The interest earned is the difference between the final balance and the principal:

I = $800,000 - $350,000 = $450.000

Solving the first equation for r:

\displaystyle r=\frac{I}{P.t}

Substituting:

\displaystyle r=\frac{450,000}{350,000\cdot 19}

Calculating:

r = 0.0677

Or, equivalently:

r = 6.77%

The annual interest is 6.77%

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
Serggg [28]

Answer:

The last one (x,y)->(x+3,y+5)

Step-by-step explanation:

Whenever you move the x coordinate it’s the opposite, for example translated 3 units the the left is +3 and translated 3 units to the right is -3.

Whenever you move the y coordinate it’s normal so up 5 units means +5 and down means -5.
