PLEASE HELP I'LL GIVE YOU 23 POINTSTHERE IS A SCREEN SHOT BUT JUST IN CASE YOU CANT ACCESS IT I'LL ADD THIS!
In the figure shown, line AB is parallel to line CD.

Part A: What is the measure of angle x? Show your work. (5 points)

Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)

AB and CD are parallel lines, and PQ and PR are transversals which intersect AB at P and CD at Q and R. Angle APQ is labeled as 65 degrees, angle QPR is equal to x, angle PRD is equal to 120 degrees.

Answers

Answer 1

Answer:

Answer:

x = 55

Step-by-step explanation:

to find angle BPR you would do:

180 - 120 = 60

so BPR is 60°

now to find x you do this:

65 + 60 + x = 180

125 + x = 180

x = 55

Answer 2

Answer:

Answer:

45 degrees

Liana started to evaluate the function f(x) = 2x2 – 3x + 7 for the input value 2.f(x) = 2(2)2 – 3(2) + 7

= 2(4) – 3(2) + 7

What is the value of the function when x = 2?

Answers

f(x) = 2x² - 3x + 7

x = 2

f(2) = 2(2²) - 3(2) + 7
f(2) = 2(4) - 6 + 7
f(2) = 8 - 6 + 7
f(2) = 15 - 6
f(2) = 9

The value of the function when x = 2 is 9.

If you would like to know the value of the function when x = 2, you can calculate this using the following steps:

f(x) = 2 * x^2 - 3 * x + 7
x = 2
f(2) = 2 * 2^2 - 3 * 2 + 7 = 2 * 4 - 6 +7 = 8 - 6 + 7 = 9

The correct result would be 9.

Irene received $425 in annual interest on a principal investment sum of $5,000. What was the simple interest rate for his return???

Answers

Irene received 425 dollars as interest rate for his principal investment which is 5000 dollars.
Let's solve for the interest rate:
=> 425 / 5000 dollars = 0.085
=> 0.085 * 100% = 8.5%
Thus the simple interest or annual interest to her investment is 8.5%

What is the equation in slope-intercept form of the line that passes through the points ( -4 , 2) and (12, 6)?Group of answer choices

y = 0.25x − 4.5

y = 4x − 42

y = 4x + 18

y = 0.25x + 3

Answers

Answer:

y = 0.25x + 3

Step-by-step explanation:

solve for slope:

(6-2)/(12+4) = 1/4

solve for b:

6 = 12(1/4) + b

6 = 3 + b

b = 3

equation can also be y = 1/4x + 3

Step-by-step explanation:

let the equation be y = mx + b.

m = (6 - 2)/(12 - (-4)) = 1/4

sub (12, 6):

6 = 1/4(12) + b

b = 3

therefore, equation of the line is y = 1/4x + 3, aka option 4
