The perimeter of a rectangular pool i 110 feet. If the pool i 17 feet wide, find the length of the pool
It will be 38 feet long
What is perimeter?The perimeter is the space surrounding a shape's edge.
The sum of the lengths of all the sides in a rectangular shape is its perimeter. P = 2( L+B)
Given that a rectangle's width is 17 feet and its perimeter is 110 feet, the length will be P = 2 (L + B)
110 = 2 (L + 17)
55 - 17 = L.
The pool is therefore 38 feet long.

A graph of the given system of equations f(x) = 2x² - 8x + 3 and g(x) = -2x + 3 is shown in the image attached below.
The points that make both equations true is (0, 3)
What is a graph?In Mathematics, a graph can be defined as a type of chart that is typically used to graphically represent data points or ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate and y-coordinate respectively.
What is a quadratic function?In Mathematics, the graph of every quadratic equations (functions) is either an upward or downward parabola, which is typically a u-shaped curve. This ultimately implies that, the graph of a quadratic equation (function) would always form a parabolic curve.
Based on the graph (see attachment), we can logically deduce that the solution to the given system of equations is the point of intersection of the lines on the graph representing each, which is the ordered pair (0, 3);
f(x) = 2x² - 8x + 3
3 = 2(0)² - 8(0) + 3
3 = 3 (True).
g(x) = -2x + 3
3 = -2(0) + 3
3 = 3 (True).

In 2017, a company's sales were about $9 million. Sales increased at an approximately constant rate and reached
about $14.5 million in 2020, Estimate the sales in 2026. Show your work.
Answer: To estimate the company's sales in 2026, we need to find the average increase in sales per year and then use that to predict the sales for 2026.
The total increase in sales from 2017 to 2020 was $14.5 million - $9 million = $<<14.5-9=5.5>>5.5 million.
The number of years from 2017 to 2020 is 2020 - 2017 = <<2020-2017=3>>3 years.
Therefore, the average increase in sales per year was $5.5 million / 3 years = $<<5.5/3=1.83>>1.83 million/year.
Since the average increase in sales per year was $1.83 million/year, we can estimate the sales in 2026 by adding that amount to the sales for each year from 2020 to 2026. For example, the estimated sales for 2021 would be $14.5 million + $1.83 million = $16.33 million. Similarly, the estimated sales for 2022 would be $16.33 million + $1.83 million = $18.16 million, and so on.
Using this method, we can estimate that the sales for 2026 will be $26.73 million.

2. (-8, 0); m = -4 :- y = -4x - 24
3. (-6, -10); m = 1/6 :- y = -1/6x - 9
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
The equation of the lines will be,
y = mx + c
y = 3x + c
-1 = 4 x 3 + c
c = -13
y = 3x - 13
y = mx + c
y = -4x + c
0 = -4 x -8 + c
c = -24
y = -x -24
y = mx + c
y = 1/6x + c
-10 = -1 + c
c = -9
y = -1/6x - 9
Therefore, the equation of the lines is,y = 3x - 13 y = -4x - 24 and y = -1/6x - 9.

Lela is making peach pies. She uses 9 peaches for each pie. If she uses 18 peaches for 2 pies and 36 peaches for 4 pies, how many peaches will she need for 7 pies?
A. 45 B. 54C. 63D. 70Answer : C. 63Explanation :As, Lela is using 9 peaches for each pie.
Thus, she used 18 peaches for 2 pies, which is 2 times 9 and 36 peaches for 4 pies, which is 4 times 9. Therefore, to make 7 pies, she would need :
Peaches used for one pie = 9
=> Peaches used for 7 pies = 9 × 7
=> Peaches needed for 7 pies = 63
Hence, she will need 63 peaches to make 7 pies.

Out of the 14 coins she has, she will have 4 dimes, totaling $2.5.
What is expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression in mathematics is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.) You can think of expressions as being comparable to phrases. A phrase in language may contain an action on its own, but it does not constitute a whole sentence.
Here,
Let n be the nickels, d be the dimes, q be the quarters.
Total coins=14
Total amount=$2.5
n=2d
d=2q
q=d/2
d+q+n=14
d+2d+d/2=14
2d+4d+d=28
7d=28
d=4

#9 -5=9+(c divide by 4) *
O A. c = -56
O B. c = 56
O C. c = -16

After solving the given equation for c, we know that the value of c is (A) -56.
What are equations?Equivalent systems refer to sets of equations with the same solution.
We can create an analogous system from a system of two equations by replacing one equation with the total of the two equations or by replacing an equation with a multiple of itself.
So, we have the equation:
-5 = 9+(c/4)
Now, solve for the subject c as follows:
-5 = 9+(c/4)
-5 -9 = (c/4)
-14 = c/4
c = -14*4
c = -56
