Answer:

y = -2x + 12

Step-by-step explanation:

Step 1: find the slope

y = 1/2x + 5

The equation of the line is

y = mx + c

m - slope

m = 1/2

Note : if two lines are perpendicular to the other, both lines are negative reciprocal of each other

m = -2

Step 2 : using a point slope form

y - y1 = m( x - x1)

( 2 , 5)

x1 = 2

y1 = 5

y - 2 = -2( x - 5)

y - 2 = -2x + 10

y = -2x + 10 + 2

y = -2x + 12

The equation of the line is

y = -2x + 12

I dunno the answer so I just found another answer I found in here for this question:P

The perimeter of a television screen is 42 inches. The screen is 8 inches tall. How wide is it?

Leni [432]

Answer:

13 inches

Step-by-step explanation:

Perimeter is all the sides added so your equation would be 8+8+x+x=42 then you combine like terms. 16+2x=42. Next you would isolate the variable 2x=26 and the divide the 2 on both sides and you get x=13. Meaning your width is 13 inches long

A professor gave her students six essay questions from which she will select three for a test. A student has time to study for o

Alenkinab [10]

The probability that of the questions studied, all three were the test questions selected by the professor is 0.05.

<h3>How to find the probability?</h3>

We can find the probability by dividing the total number of favorable events by the total number of events.

The total number of events is given by $6C_{3}$ .

The total number of favorable events is given by $3C_{3}$ .

The probability is given by = Favorable events/Total number of events

= $\frac{3C_{3}}{6C_{3}}$

= $\frac{1}{\frac{(6)(5)(4)}{(1)(2)(3)} }$

= $\frac{1}{(5)(4) }$

= 0.05

The probability that all three questions are selected by the professor for the test is found to be 0.05.

Therefore, we have found that the probability that of the questions studied, all three were the test questions selected by the professor is 0.05.

In 25 words or fewer, is this solution reasonable? Why or why not?

Julli [10]

Step-by-step explanation:

This solution is reasonable because equal slopes are parallel and negative reciprocals are perpendicular. Four right angles make up a rectangle, and this fulfills it
