Answer:

D

Step-by-step explanation:

I believe D is the answer because 10^-3 = 0.001 ; there is only one answer that has 0.001 in the correct exponential form (10^-3).

Also, for the future, to correctly figure out what the exponential form, try to take the number given, let's say 10^-2 (^ means to the power of), and move the decimal place to the left, two decimal places (because of the power of -2).

Ex: 10.0 --> 0.01

Hope this helped!

Compare the quantities in Column A and Column B.
GaryK [48]

The y-intercept of 2y = 3x - 4 and the y-intercept of 4x - 2y=4 are equal

The equations are given as:

2y = 3x - 4

4x - 2y=4

Make y the subject in both equations

<u>First equation</u>

2y = 3x - 4

y = \frac 32x - 2

<u>Second equation</u>

4x - 2y=4

y = 2x - 2

A linear equation is represented as:

y = mx + b

Where b represents the y-intercept

So: By comparison,

b_1 = 2 --- the y-intercept of the first equation

b_2 = 2 --- the y-intercept of the second equation

2 = 2.

Hence, the y-intercept of 2y = 3x - 4 and the y-intercept of 4x - 2y=4 are equal

This is an easy question but it’s kind of stumping me, please help!!
Kryger [21]

Answer:

-3/2

Step-by-step explanation:

Remeber, to find slope we use this formula:

y - y all over x - x, or (y-y) / (x-x)

(6-9) / (5-3)

-3 / 2

= -3/2

Solve each equation. Check your solution.<br><br><br> 3x 32 = 7x + 28
skad [1K]

Answer:

x= 28 /89

Step-by-step explanation:

3x(32)=7x+28

Step 1: Simplify both sides of the equation.

96x=7x+28

Step 2: Subtract 7 from both sides.

96x   7x+28

−7             −7

89x=28

Step 3: Divide both sides by 89.

89x /89 = 28 /89
