Answer:
x = 9
Step-by-step explanation:
Since the angle is bisected by rhe segment then the ratio of the sides to the corresponding parts of the base are equal, that is
=
( cross- multiply )
20x = 180 ( divide both sides by 20 )
x = 9
Answer: D
<u>Step-by-step explanation:</u>
x - 2 = 0 --> x = 2
Using synthetic division:
2 | 4 -5 3 -1
|<u> ↓ 8 6 18</u>
4 3 9 17 ← this is the remainder!
Using remainder theorem:
f(x) = 4x³ - 5x² + 3x - 1
f(2) = 4(2)³ - 5(2)² + 3(2) - 1
= 32 - 20 + 6 - 1
= 17
M = 3
b = 8.25
you'll plug those numbers into this equation
y = mx + b
y = 3x + 8.25
your answer is D
Answer:
21.1%
Step-by-step explanation:
(25 - 24.3) / 1.2 = 0.5833 z score = 78.9%
You need the percent that spend more than 25 hrs per week, so 100 - 78.9 = 21.1%
First you have to find the slope by subtracting y2 in this case (2) from y1 (8) dividing it over the subtraction of x2 (-8) and x1 (4) then once you get that you pick a point whether it’s (4,8) or (-8,2), plot it using the slope given to you and you’re done.
