Examine the system of equations.

MakcuM [25]

Answer:

$\boxed{\boxed{\sf x=-3}}$

Step-by-step explanation:

$\sf y = -3x - 2$

$\sf y=7$

We'll substitute y into the equation:

$\sf 7 = -3x - 2$

Switch sides:

$\sf -3x-2=7$

Add 2 to both sides

$\sf -3x-2+2=7+2$

$\sf -3x=9$

Divide both sides by -3:

$\sf \cfrac{-3x}{-3}=\cfrac{9}{-3}$

$\sf x=-3$

Therefore, the value of x/solution is -3

Four times a number is equal to the number increased by 15. Enter the equation that represents Karla's sentence into the box. Us

Montano1993 [528]

Answer:

The equation that represents Karla's sentence is 4y = y + 15

Step-by-step explanation:

From the question,

Four times a number is equal to the number increased by 15. To write the equation that represents the sentence, we will have to use a variable to represent the unknown number.

Since we are asked to use y for the variable, that is, let the number be y

Then

The statement, "four times a number" will be

4×y = 4y

and this is equal to the number increased by 15,

The number increased by 15 means y + 15.

Hence, the equation becomes

4y = y + 15

This is the equation that represent Karla's sentence.

If desired,

The unknown number can be determined by solving for y in the equation

4y = y + 15

First, Collect like terms

4y - y = 15

3y = 15

Then, Divide both sides by 3

3y/3 = 15/3

y = 5

Hence, the variable (unknown number) is 5.

Dina invests $600 for 5 years at a rate of 2% per year compound interest.

kenny6666 [7]

Answer:

The investment after 5 years is $ 662.45.

Step-by-step explanation:

Principal, P = $ 600

Time, t = 5 years

Rate of interest, R = 2 %

Time , t = 5 years

The amount after the time 5 years is

$A = P \times \left ( 1+\frac{R}{100} \right )^t\\\\A = 600\left ( 1+0.02 \right )^5\\\\A = 662.45$

So, the investment after 5 years is $ 662.45.
