Your answers to this is the first and third file.

The functions are increasing because the arrow is pointing upwards.
Let me teach you something I learned in school!
Okay, you know how you read words from left to right? Well, it's the same with math like this! If you see a line on a graph pointing upwards when you look at it from left-to-right, then it's an increasing function. If it's the other way around, it's decreasing.

Quincy is using 320 pieces of stone tile to make red white and blue mosaic. If 20% of the pieces are blue and 35% are white how many pieces are red?
Answers
20% = Blue tiles
35% = White Tiles
100% - 55% = Red Tiles = 45%
45% of 320
320 x 0.45 = 144 Red tiles
To determine the number of red tiles in Quincy's mosaic project, the percentage of blue and white tiles were converted to actual numbers and subtracted from the total. This calculation revealed that there are 144 red tiles.
Explanation:Quincy is using 320 pieces of stone tile to make a mosaic.
It is given that 20% of the pieces are blue, and 35% are white. To find out how many tiles are red, we start by calculating the number of blue and white tiles:
Blue tiles: 20% of 320 = (20/100) * 320 = 64 tilesWhite tiles: 35% of 320 = (35/100) * 320 = 112 tilesAdding the blue and white tiles together gives us 64 + 112 = 176 tiles.
Since the total number of tiles is 320, the number of red tiles will be the remaining tiles after subtracting the blue and white tiles:
Red tiles = Total tiles - (Blue tiles + White tiles) = 320 - 176 = 144 red tiles.
Therefore, 144 pieces of stone tile are red in Quincy's mosaic project.
X-42=-33 what is the solution ?
Answers
x = 42 - 33
x = 9
-42 + 42 + x which is also equals to x = -33 + 42↓
-42 + 42 →0; 0 + x → -33 + 42; x = -33 + 42 ↓
If you add these to from each other -33 + 42 it would equal to "9"
Therefore, "x" = 9 :)
What numbers have an absolute value of 9
Answers
The numbers that have an absolute value of 9 are 9 and -9.
In general, the absolute value of a positive number x is |x| = x, and the absolute value of a negative number -x is |x| = -(-x) = x.
So, for any number x or -x where x ≠ 0, its absolute value is always positive and equal to the positive value of "x."
The absolute value of a number is the distance of that number from zero on the number line.
Since both 9 and -9 are 9 units away from zero, their absolute values are both 9.
Hence, the numbers are 9 and -9.

Explain the meaning of (2,40).
Answers
Coordinate points - (x,y)
They are used to locate a point on a coordinate plane, or graph.
The correct answer for the meaning of (2,40) is they represents the coordinates of a point on x-y plane.
What are Co-ordinates?
Coordinates are sets of values used to represent the position or location of a point in a given space.
The number of values in a coordinate set depends on the dimensionality of the space being considered.
In two-dimensional space (2D), coordinates typically consist of two values, often denoted as (x, y).
Given points:
(2,40)
X-coordinate = 2
y-coordinate =40
The correct answer is (2,40) represents X and Y coordinate on a 2D plane.

The scale on Krystal's map is 1 inch = 18 miles. How far apart are Greenville from north valley?
Answers
According to Krystal's map scale, the distance between Greenville and North Valley is 72 miles.
To find the distance between Greenville and North Valley using Krystal's map scale of 1 inch = 18 miles, you need to determine the distance represented by the two locations on the map and then convert it to real-world miles.
First, measure the distance between Greenville and North Valley on the map. Let's say it's 4 inches.
Now, multiply the measured distance on the map by the scale factor:
4 inches * 18 miles/inch = 72 miles.
Thus, according to Krystal's map scale, the distance between Greenville and North Valley is 72 miles.
This means that in reality, Greenville and North Valley are 72 miles apart.
This calculation is based on the given scale and assumes that the map accurately represents the geographical locations of Greenville and North Valley.
Always consider real-world conditions and factors like road layouts when planning actual travel.

A parachutist's rate during a free fall reaches 135 miles per hour. What is this rate in feet per second? At this rate, how many feet will the parachutist fall during 2 seconds of free fall? In your computations, use the fact that 1 mile is equal to 5280 feet. Do not round your answers. THANK YOU!!!
Answers
135 miles per hour = 712,800 feet per second
712,800+712,800= 1,425,600 feet per 2 seconds
The parachutist will free fall 1,425,600 feet in 2 seconds.
Answer:
Parachutist will fall 396 feet in 2 seconds.
Step-by-step explanation:
A parachutist's rate during a free fall reaches 135 miles per hour.
We have to calculate this rate in feet per second.
Rate = 135 [tex]\frac{miles}{hour}[/tex]
= 135×[tex]\frac{5280}{60\times 60}=135\times \frac{5280}{3600}[/tex] feet per second
= 135×1.467 feet per second
= 198 feet per second
Now we have to calculate the fall of the parachutist during 2 seconds.
Fall = 198×2 = 396 feet

write the missing exponent. 1/169 = (1/13)
Answers
Answer:
[tex]\frac{1^2}{13^2}=(\frac{1}{13})^{2}[/tex]
Step-by-step explanation:
We have been given an equation [tex]\frac{1}{169}=(\frac{1}{13})^{*}[/tex]. We are asked to write the missing exponent for our given equation.
We can see that 169 is square of 13, so we can write left side of our equation as:
[tex]\frac{1}{13^2}=(\frac{1}{13})^{*}[/tex]
We can raise 1 to any power and answer will be same.
Raising 1 to 2nd power, we will get:
[tex]\frac{1^2}{13^2}=(\frac{1}{13})^{*}[/tex]
Since both numerator and denominator is raised to 2nd power, so we can raise [tex](\frac{1}{13})[/tex] to 2nd power as:
[tex]\frac{1^2}{13^2}=(\frac{1}{13})^{2}[/tex]
Therefore, our missing exponent is 2.

The y-intercept of the function y = 2x + 1 is equal to the y-intercept of the function represented in the graph.
From the given graph: the y-intercept is = 1.
To find the y-intercept of y=2x+1 we compare it with y=mx+b.
So, b=y-intercept=1.
Both y-intercepts are 1.
It means the y-intercept of the function y = 2x + 1 is equal to the y-intercept of the function represented in the graph.
