Answer:

6

Step-by-step explanation:

x-7=1/4 (x-10)

distrubute 1/4 through the parentheses

x-7=1/4x -5/2

multiply both sides of the equation by 4

4x-28=x-10

4x-28-x=-10

3x=-10+28

3x=18

divide both by 3

x=6

Jasmine invests $2,658 in a retirement account with a fixed annual interest rate of 9% compounded continuously. What will the ac
Feliz [49]

Answer:

$10,253.04

Step-by-step explanation:

You are going to want to use the continuous compound interest formula, which is shown below.

A = Pe^{rt}

<em>P = principal amount</em>

<em>r = interest rate (decimal)</em>

<em>t = time (years)</em>

<em />

First, change 9% into a decimal:

9% -> \frac{9}{100} -> 0.09

Next, plug the values into the equation:

A=2,658e^{0.09(15)}

A=10,253.04

The account will have $10,253.04

Alex73 [517]

y=-3x+9

explanation

m=-3 (X1,Y1) = (4,-3)

(y-y1)= m×(x-x1)

(y-(-3))=-3(x-4)

y+3= -3x+12

y=-3x+12-3

y=-3x+9

Which equation has NO solution? A) 15x + 12 3 = 5x + 4 B) 8 − 4x 10 = 4 + 2x C) 4x − 20 2 = 2x − 10 D) 15x + 5 3 = 5x + 6
jenyasd209 [6]

Assumption:

<em>Something is missing in question. If we see deeply it is apparent that there is some issue with option b i.e. </em><em>B) 8 − 4x 10 = 4 + 2x </em><em>we assume that the questioner want to type </em><em>B) 8-4x^10 = 4 + 2x.</em>

Answer:

The correct answer is <em> </em><em>B) 8-4x^10 = 4 + 2x.</em>

Step-by-step explanation:

All equations given is the question can be solve easily to determine the value of x. However if we solve equation mentioned in option b we cannot  get single answer easily.

For example value of x in eq given in option A

15x + 123 = 5x+4

1oX = -119

 X = -119/10
