Simplify the expression (k2)4

1 answer:

6 0

4 times 2= 8. so, 4times k2 = k8. To understand this better, imagine that k equaled 2. That would make the expression above = (2x2)4, which would equal 16. However, since we don't know the value of k, we have to use the numbers that we already have, It would be like solving the expression: (2x2)4 without multiplying the first 2. It would then be 2x8. So, we just simplified it, we didn't solve it.

Put the following equation of a line into slope-intercept form, simplifying all fractions. 2x-3y=−9

Paha777 [63]

Answer:

Step-by-step explanation:

Slope-intercept from: y = mx +c

Here, m is the slope & c is the y-intercept.

So, we have to isolate y. To isolate y first subtract 2x from both sides.

2x - 3y = -9

-3y = -2x -9

Now, divide the entire equation by the co efficient of y (-3)

$\dfrac{-3}{-3}y=\dfrac{-2}{-3}x-\dfrac{9}{-3}\\\\\\y=\dfrac{2}{3}x + 3$

Several students made comments about this image.

Answer:

The third comment is the true one: "If I know the measures of angles C and B, I can find the measures of A and D."

This is because you can use the angle B to find angle A by subtracting it from 180, and you can find angle D by adding together C and B and subtracting that from 180.

I hope this helps!

I WILL GIVE BRAINLIEST TO WHOEVER ANSWERS FIRST! A circle has a diameter AB, and its center is at (-3, 3). Point A is at (1/2,6)

kow [346]

Using the mid-point concept, it is found that point B is located at coordinates (-6.5, 0).

<h3>What is the midpoint concept?</h3>

The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.

The center is the midpoint of the two coordinates of the diameter, hence:

$C = \frac{B + A}{2}$

For the x-coordinate:

$-3 = \frac{x + 0.5}{2}$

x + 0.5 = -6

x = -6.5

For the y-coordinate:

$3 = \frac{y + 6}{2}$

y + 6 = 6

y = 0
