Which point is best represented by the ordered pair (2, -5.5)?
A point W
b point V
c point S
d point R
Answers
Answer:
B
Step-by-step explanation:
Answer:
The answer is A, Point W.
This is because (2, -5.5) is equal to (x, y). So, x would be 2, while point y will be -5.5. Point W represents this because it goes to 2 on the x axis, and down to -5.5 on the y axis.

Answer:
x = 63.5 degrees
Step-by-step explanation:
use sine:
sine = [tex]\frac{opposite}{hypotenuse}[/tex]
sine x = [tex]\frac{17}{19}[/tex]
sine x = 0.8947
sine-1 of 0.8947 = 63.4699
x = 63.4699

Answers
Answer:
x=5.5, -5.5
you can use a calculator too
3x^2 - 75 = 90
1. Move the constant to the right
3x^2 = 165
2. Divide by 3
X^2 = 55
Therefore: x= +/- square root 55
X^2 = 115
Collins has a part-time job as a dog walker. The table below shows the amount of money Collins earned for different numbers of hours of work:

8
66
Part A: What are the missing numbers in the table? Show your work. (4 points)
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
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)

To find:
All the real solutions.
Solution:
We have,
[tex]2x^3-3x^2+18x-27=0[/tex]
It can be written as
[tex]x^2(2x-3)+9(2x-3)=0[/tex]
[tex](2x-3)(x^2+9)=0[/tex]
Using zero product property, we get
[tex](2x-3)=0[/tex] and [tex](x^2+9)=0[/tex]
[tex]2x=3[/tex] and [tex]x^2=-9[/tex]
[tex]x=\dfrac{3}{2}[/tex] and [tex]x=\pm\sqrt{-9}[/tex]
We know that [tex]x=\pm\sqrt{-9}[/tex] is an imaginary number because there is a negative sign under the square root.
Therefore, [tex]x=\dfrac{3}{2}[/tex] is the only real solution of the given equation.

The system of equations that describes the problem situation is y=250+0.12x and y=475+0.08x. The correct option is D.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that The first store will pay her a weekly salary of $250 plus a commission of 12% of her sales. Therefore, the equation can be written as,
Total earning = Weekly salary + 12% of weekly sales
y = 250 + 0.12x
Also, The second store will pay her a weekly salary of $475 plus an 8% commission. Therefore, the equation can be written as,
Total earning = Weekly salary + 8% of weekly sales
y = 475 + 0.08x
Hence, the system of equations that describes the problem situation is y=250+0.12x and y=475+0.08x.

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.
