AB is a straight line solve for x please help this quiz is so hard

Mathematics
1 answer:
LenaWriter [7]3 years ago
8 0

Answer:

x = 29

Step-by-step explanation:

Since AB is a perfectly straight line, that means its angle is exactly 180°. Given that, we can tell that the three angles all add up to 180°. If we set the equation to equal 180 by adding all the given angles up, we will find the answer.

64 + x + 3x = 180

Combine like terms.

64 + 4x = 180

Subtract 64 from 180 to get 4x by itself.

180 - 64 = 116

4x = 116

Now get "x" completely alone by dividing both sides of the equal sign by 4.

4x/4 = x

116/4 = 29

<u>x = 29</u>

5x^2 + 5x + 5

-3x + 10

22

Step-by-step explanation:

find the highest exponent of each polynomials:

22=> 0 degree

-3x(equals to -3x^1) + 10=> 1st degree

5x^2 + 5x + 5=> 2nd degree

-x^3 + 3x^2 + 2x + 4=> 3rd degree

2x^4=> 4th degree

Find the equation for the line that passes through the point (2,2), and that is parallel to the line with the equation y=3/4x-4
telo118 [61]

Answer: y=3/4x  + 1/2

Step-by-step explanation: Parallel lines must have the same slope, so you already know the equation must be something like y=3/4x+b. You are given a point that the line goes thru(2,2), so you can plug this point into the equation to solve for b.

(2)=3/4(2) + b

2=6/4 + b

2= 3/2 + b

b= 2-3/2

b=4/2- 3/2

b=1/2

so y=3/4x + 1/2

On a road trip,drove at a speed of 60 miles per hour for the first two hours. She then increased her speed by 25%. How fast was
love history [14]
This can either be done by multiplying with 125% (1.25) or, by dividing by dividing on 4 and adding a part.

This is the easiest way, tho.

60*1.25=75

The correct answer is 75 mph.
