Answer:
Step-by-step explanation:
1. f(x) = 5x² + 3x - 1
a. f(0) = 5·0² + 3·0 - 1 = -1
b. f(-1) = 5(-1)² + 3(-1) - 1 = 1
Do the same for f(2), f(√2), f(a+2), and f(a).
Then do the same thing for the next function.
2. f(x) = x/(1-x)
a. f(0) = 0/(1-0) = 0
Do the same for f(-1), f(2), f(√2), f(a+2), and f(a).

Answers
Answer:
Step-by-step explanation:
(2x^2-32)/(x^2 + 10x + 24) is less subject to misinterpretation. Write these factors in a vertical column:
(2x^2-32)
------------------------- and then factor numerator and denominator separately:
(x^2 + 10x + 24)
2(x^2 - 16) 2(x - 4)(x + 4) 2(x - 4)

On a coordinate plane, the orange K is shifted to form the purple K, reflected across the x-axis to form the green k, and rotated to form the black k. Which image is a reflection of the orange letter K in Quadrant I?
Answers
Answer:
the green kin quadrant IV
Step-by-step explanation:
i took the quiz and got it right
Point k is reflected across the y-axis to create point k'.
What is reflection?A reflection in mathematics is a mapping from a Euclidean space to itself that is an isometry with a set of fixed points known as the hyperplane, also known as the axis or plane of reflection.
The mirror image of a figure in the axis or plane of reflection is the image produced by a reflection.
From the graph, we can see that point k has a negative x-coordinate, so option A is wrong. Also, point K is located in quadrant II, not in quadrant IV
Point K is not reflected across the x-axis to create K'. For reflection across the x-axis to occur, the point (x,y) across the x-axis will change to (x, -y).
Point K is reflected across the y-axis to create point K'. We can see from the graph that the reflection of the point (x,y) across the y-axis is the point (-x, y)

Yasmin arived home from play practice began 20 minutes after the final bell and lasted for a half hour. When did school end.
Answers
Answer:
the school ended at 3:20pm
Step-by-step explanation:
Since Yasmin arrived home from play practice at 4:25 p.m.
The walk home took 15 minutes.
And, The practice starts 20 minutes after the final bell and lasted for a half hour.
Now Total time taken in all activities would be
= 15 + 20 + 30
= 65 minutes
Now deduct 1 hour and 5 minutes from 4:25 pm
i.e.
1 hour prior to 4:25 pm i.e. 3:25 pm
And, 5 minutes prior 3:25 pm i.e. 3:20 pm
So, the school ended at 3:20pm

Part B: Collins also does part-time yard work. The ratio of the number of hours Collins works to the money he earns in dollars is 1:7. Create a table to show the money earned by Collins for 5, 6, and 8 hours of doing yard work. (3 points)
Part C: How many more dollars does Collins earn doing yard work for 5 hours than working as a dog walker for 5 hours? Show your work. (3 points)
Answers
Answer:
See below.
Step-by-step explanation:
Part A:
For Dog walking, he earns $30 for 5 hours of work.
He earns $36 for 6 hours of work.
$30/5 hours = $6/hour
$36/6 hours = $6/hour
He earns $6/hour dog walking.
For 8 hours, he earns 8 hours * $6/hour = $48
To earn $66, he works 66/6 = 11 hours.
5 30
6 36
8 48
11 66
Part B:
He earns $7/hour for yard work, so multiply the number of hours by 7 to find the money he earns.
Table for yard work
Hours Money
5 $35
6 $42
8 $56
Part C:
For 5 hours, he earns $35 for yard work and $30 as a dog walker.
$35 - $30 = $5

Answers
Answer:
2
Step-by-step explanation:
The slope is the rise over the run. 2 simple coordinates I can see is (6,2) and (7,4). I usually like to visualize it instead of actually solving it mathematically. So, we can start at (6,2). The point (6,2) goes up 2 and 1 to the right in order to get (7,4.) So since the slope is rise over run ( y/x) it would be 2/1 because we went 2 up the y axis and 1 to the right of the x axis. So 2/1 is 2. Therefore, 2 is the answer. I'm sorry if my explaining isn't the best... I hope this helps though!!

Staples sells boxes of pens for ($10) and rubber bands for ($24). Leona ordered a total of 24 cartons for $210. How many boxes of each did Leona order? Hint: Let P = Pens.
Answers
Answer:
Leona ordered 19 boxes of pens and 5 rubber bands
Step-by-step explanation:
Let there are p pen and b rubber bands.
ATQ,
p+b = 24 ...(1)
and
10p+4b = 210 ...(2)
Multiply equation (1) by 10.
10p+10b = 240 ...(3)
Subtract equation (2) from (3).
10p+10b-(10p+4b ) = 240-210
6b = 30
b = 5
Put the value of b in equation (1).
p+5 = 24
p = 19
Hence, Leona ordered 19 boxes of pens and 5 rubber bands.
a) write √3×√6 in the form of b√2 where b is the insteger
b) simplify √8×√18
