Answer:

y= -3/2x+9

Step-by-step explanation:

Well we have to know that to find a line perpendicular to a given line, you have to have opposite slopes. So that makes the equation begin as y=-3/2x because it's opposite of y=2/3x. Then we have to make sure it goes through the point (4,3). To do that, I tweaked the numbers in my graphing calculator and it worked with 9! So the equation is y= -3/2x+9

A classmate wrote the solution to the inequality |-4x + 1| > 3 as show below. Describe and correct the error.

Answer:

See below.

Step-by-step explanation:

The last step is incorrect. When we divide both sides by a negative the inequality is flipped. The answer is x < -1/2.

Also they omitted the other possibility that the expression in the vertical lines could be negative.

We also have the inequality

- 4x + 1 < - 3

-4x < -4

x > 1.

Evaluate b²c¹ for b=8 c=-4

AVprozaik [17]

Answer:

The answer is -256.

Step-by-step explanation:

You have to substitute the value of b and c into the expression :

${b}^{2} {c}^{1}$

Let b = 8,

Let c = -4,

${8}^{2} \times { - 4}^{1}$

$= 64 \times - 4$

$= - 256$

Ludmilka [50]

The answer is 180 degrees.

A right angle formed at the edge of any circle will always create an arc of 180 degrees. This is true no matter where it is placed and no matter the side lengths.
