Answer:
Y = -2, X = 4
Step-by-step explanation:
When you first use the elimination method, you would multiply 2x-y = 10 by -2 so that you could get the 4x to be eliminated.
4x-3y = 22
(2x-y = 10)-2 = -4x + 2y = -20
When you add those 2 together you are left with -y = 2, which you divide by negative to get y = -2. Then you substitute -2 for y to solve for x. I substituted the bottom equation
2x - (-2) = 10
2x +2 = 10
2x = 8
Divide both sides by 2 to get x = 4.

Dustin has a spinner that is divided into 5 equal-size sections colored pink, blue, orange, white, and green. What is the probability that Dustin spins pink on the 1st spin and then spins a color other than pink on the 2nd spin?
Answer:
1/6
Step-by-step explanation:
1st spin:
1 out of the 5 sections are pink, so the probability of spinning a pink on the 1st spin is 1/5.
2nd spin:
5 out of the 6 sections are not pink, so the probability of spinning a pink on the 2nd is 5/6.
Multiply the probabilities of the two spins to get the answer.
[tex]\frac{1}{5} *\frac{5}{6} =\frac{5}{30} =\frac{1}{6}[/tex]

What is the y-intercept of the line?
Answer:
3
Step-by-step explanation:
How I found it?
Look at the middle of the line where is the line at, thats ohw you find the y-interccept.
3
Solution:The y-intercept is the point where the graph intersects the y-axis.Usually the y-intercept is written as(0, b) where "b" represents the y-intercept.The given graph intersects the y-axis at (0, 3)Therefore, the y-intercept is equal to (0, 3) or 3.Hope it helps.

Under her cell phone plan, Nicole pays a flat cost of $35 per month and $5 per gigabyte. She wants to keep her bill under $60 per month. Use the drop-down menu below to write an inequality representing gg, the number of gigabytes she can use while staying within her budget.
Answer:
< 5 gigabytes
Step-by-step explanation:
Let the number of gigabytes be represented as: g
Under her cell phone plan, Nicole pays a flat cost of $35 per month and $5 per gigabyte. She wants to keep her bill under $60 per month.
Under $60 = less than (<) $60
Hence, our inequality equation is given as:
$35 + $5 × g < 60
35 + 5g < 60
Collect like terms
5g < 60 - 35
5g < 25
g < 25/5
g < 5 gigabytes
Therefore, the number of gigabytes she can use while staying within her budget less than 5 gigabytes
Answer:
g<5

Find the area of the shaded region
8cm
After answering the query, we may state that area of shaded region = 100.48-64 = 36.48 sq cm.
What is circle?Each point in the plane that is a certain distance from the centre (another point) forms a circle. Thus, it is a curve composed of points whose are separated from another point in the plane by a certain distance. Additionally, at every angle, it is alternately symmetric about the centre. The closed, two-dimensional plane of a circle has every pair of points equally separated from the "centre." By drawing a line through the circle, one may create a line of circular symmetry. Additionally, at every angle, it is rotationally equal about the Centre.
here, by Pythagoras theorem
diagonal = [tex]\sqrt(8^2 + 8^2) = \sqrt(64+64) = \sqrt(128) = 8\sqrt2[/tex]
radius = [tex]4\sqrt2[/tex]
area of circles = [tex]\pi r^2 = 3.14 * (4\sqrt2)^2 = 100.48 cm^2[/tex]
area of square = 8*8 = 64 sq cm
area of shaded region = 100.48-64 = 36.48 sq cm.

1a.) Brian borrowed 4 non-fiction books from the library. This was 25% of the
books he checked out. How many books did Brian check out? *
Answer:
Total number of books borrowed= 16
Step-by-step explanation:
Giving the following information:
Number of non-fictions books= 4
Percentage of books borrowed= 25% = 0.25
To calculate the total number of books borrowed, we need to use the following formula:
Total number of books borrowed= 4 / 0.25
Total number of books borrowed= 16
