Answers

Answer:

Whichever line has a slope of -2

rewrite in slope intercept

y=mx+b     where m=slope

y=-2x+7

-2 is the slope of the original line

a parallel line will never intersect

the parallel line must have the same slope

a. x = 15, y = 40
b. x = 30, y = 40
c. x = 15, y = 20
d. x = 30, y = 20

Answers

Answer: a. x = 15, y = 40

Step-by-step explanation:

So we already know that ΔABC and ΔFDE are congruent, which means their angles are equal. Based on this information, we could note that:

∠A = ∠F

∠C = ∠E

∠B = ∠D

Since we already know the measurement of ∠B, we could then conclude that ∠D, or y, is equal to 40°. This leaves us with two possible answers, a or b.

In order to find the value of x, we need to know the measurement of ∠F. And in order to find ∠F, we need to find the measurement of ∠A. We already know that the angles in a triangle sums up to 180°. So we would start as the following.

∠A + ∠B + ∠C = 180

We first substitute the known measurements.

∠A + 40 + 110 = 180

We then add up 40 with 110.

∠A + 150 = 180

We finally substract 150 on both sides of the equation. This gives us the measurement of ∠A.

∠A = 30°

Now that we know ∠A, we could start finding the value of x. So we already know this:

∠A = ∠F

We first substitute each angle with their known measurements.

30 = 2x

We now divide both sides by two. This gives the value of x.

x = 15

Theo used to drive 60 miles to work each day. His new home is now 20 miles away
from his job. What is the percent of
decrease in the distance Theo travels to
work? Round to the nearest tenth if
necessary.

Answers

Answer:

66.6% decrease in distance

Rounded 67%

He is traveling 1/3 of what he used to travel

Step-by-step explanation:

The percentage of decrease in the distance Theo travels to work is 66.7%.

Used concept of percentage;

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating the hundredth part of any quantity is called a percentage.

Given that;

Theo used to drive 60 miles to work each day.

And, His new home is now 20 miles away from his job.

Hence the percentage of decrease in the distance Theo travels to work is,

P = (60 - 20)/60 x 100

P = 40/60 x 100

P = 66.7%

So, The percentage of decrease in the distance Theo travels to work is 66.7%.

Answers

Answer:

the answer is the third one k > - 5

Answer/Step-by-step explanation:

 Step 1: Simplify both sides of the inequality.

[tex]\frac{1}{4}k+\frac{-3}{4}>-2[/tex]

Step 2: Add 3/4 to both sides.

[tex]\frac{1}{4}k+\frac{-3}{4}+\frac{3}{4}>-2+\frac{3}{4}[/tex]

[tex]\frac{1}{4}k>\frac{-5}{4}[/tex]

Step 3: Multiply both sides by 4.

[tex]4*\frac{1}{4}k>4*\frac{-5}{4}[/tex]

K > -5

 So according to this the value of k has to be greater than -5

You can check your answer by substituting the values in for k.

You can use a calculator..

[tex]\frac{-10-3}{4} >-2[/tex]  

[tex]\frac{-7-3}{4} >-2[/tex]

[tex]\frac{-1-3}{4} >-2[/tex]
