Hey there!
Option A.
23 + (4) - 4 * 2
= 23 + 4 - 4 * 2
= 27 - 4(2)
= 27 - 8
= 19
19 ≠ 32
Option B.
3 * 3 + (42) - 4
= 3 * 3 + 42 - 4
= 9 + 42 - 4
= 51 - 4
= 47
47 ≠ 32
Option C.
42 - 7 * 0
= 42 - 0
= 42
42 ≠ 32
Option D.
4 * 5 + 2 - 4 + 2
= 20 + 2 - 4 + 2
= 22 - 4 + 2
= 18 + 2
= 20
20 ≠ 32
None of them are equivalent to 32
Good luck on your assignment & enjoy your day!

Which inequality is shown in this graph?
6
5
(-2, 2)
-5
5
(0, -2)
The inequality of the graph is a linear inequality
The inequality shown in the graph is y > -2x -2
How to determine the inequality?The points on the graph are given as:
(x,y) = (-2,2) and (0,-2)
The slope (m) is calculatedusing:
m = (y2 - y1)/(x2 - x1)
This gives
m =(-2 - 2)/(0 + 2)
Evaluate
m = -2
The equation is then calculated as:
y = m(x - x1) + y1
This gives
y = -2(x - 0) -2
y = -2x -2
The upper part of the graph is shaded with a dotted line, so the inequality is a greater than inequality
The equation becomes
y > -2x -2
Hence, the inequality shown in the graph is y > -2x -2

The equation of a line is y = -3x – 2. What are the slope and the y-intercept of the line?
Question 9 options:
slope = -3 and y-intercept = 2
slope = 3 and y-intercept = -2
slope = 3 and y-intercept = 2
slope = -3 and y-intercept = -2
Answer:
D
Step-by-step explanation:
The formula for y=
y=(slope)x-(y intercept).
So, we are given -3 and -2 in the places-
y=(slope)-3x-(y intercept)-2
So, the answer is -3 and -2.

(- 5, 9)Step-by-step explanation:
Given system of equations
- 2x - y = 1- 4x - y = 11Express the first equation as
y = - 2x - 1Substitute the value of y into second equation
- 4x - (- 2x - 1) = 11Solve for x
- 4x + 2x + 1 = 11- 2x + 1 = 11- 2x = 102x = - 10x = - 5Find the value of y
y = - 2(- 5) - 1 = 10 - 1 = 9Answer:
(-5, 9)
Step-by-step explanation:
Given system of linear equations:
[tex]\begin{cases}-2x-y=1\\-4x-y=11\end{cases}[/tex]
To solve by substitution, use arithmetic operations to isolate y in Equation 1:
[tex]\implies -2x-y=1[/tex]
[tex]\implies -2x-y+y=1+y[/tex]
[tex]\implies -2x=1+y[/tex]
[tex]\implies -2x-1=1+y-1[/tex]
[tex]\implies y=-2x-1[/tex]
Substitute the expression for y into Equation 2 and solve for x:
[tex]\implies -4x-(-2x-1)=11[/tex]
[tex]\implies -4x+2x+1=11[/tex]
[tex]\implies -2x+1=11[/tex]
[tex]\implies -2x+1-1=11-1[/tex]
[tex]\implies -2x=10[/tex]
[tex]\implies -2x \div -2=10 \div -2[/tex]
[tex]\implies x=-5[/tex]
Substitute the found value of x into one of the equations and solve for y:
[tex]\implies -2(-5)-y=1[/tex]
[tex]\implies 10-y=1[/tex]
[tex]\implies 10-y+y=1+y[/tex]
[tex]\implies 10=1+y[/tex]
[tex]\implies 10-1=1+y-1[/tex]
[tex]\implies y=9[/tex]
Therefore, the solution to the given system of linear equations is (-5, 9).

c) 2 2/3 times greater
Step-by-step explanation:
The length of the rectangle:
The width of the rectangle is x. If you add the two widths together when finding perimeter, x + x, that would give you 2x.
Sum of widths: x + x = 2x
Use the sum of the widths to find the sum of the lengths by subtracting from the perimeter.
sum of lengths = perimeter - sum of widths
8x - 2x = 6x
Since there are 2 lengths divide by 2.
6x/2 = 3x
The length of the rectangle is 3x
Perimeter of the square:
The sides of the square are 1/4 of the length of the rectangle. "of" means to mulitply: (I made 3x a fraction by placing it over 1)
[tex]\frac{1}{4} (\frac{3x}{1} )[/tex] = [tex]\frac{3}{4} x[/tex]
Now find the perimeter of the square by multiplying the side length by 4.
[tex]\frac{3}{4}x(\frac{4}{1} )[/tex] = [tex]3x[/tex]
Last part:
solve the rectangle's perimeter by substituting x with 4.
P = 8x
P = 8(4)
P = 32 cm
Solve the square's perimeter by substituting x with 4.
P = 3x
P = 3(4)
P = 12 cm
Divide the rectangle's perimeter by the square's perimeter.
32/12 = 2 2/3 times bigger.

A horse-drawn carriage tour company has found that the number of people that take their tour depends on the price charged per customer. The more the company charges for a tour, the fewer people decide to take the tour.
The function c(x)=50+5x represents price charged per customer where x is the number of $5 increases they charge over a rate of $50 per person.
The function p(x)=100−2x represents the number of customers expected for the day, where x is the number of $5 increases they charge over a rate of $50 per person.

The Glitz Jewelry Kit contains round beads in 6 different colors plus 100 star-shaped beads.
There are 250 beads in all.
Answer:
False, it would actually be 106 beads. If this was a multiplication problem, that would also be false, because 6 times 100 is 600, not 350.
But let's attempt to make this statement true.
First/Last step: Find the missing beads.
The missing beads are 144.
Why?
Because you must add 144 to reach 250, there is no other way but to multiply. In this case, because the key word is, "In all" we are adding.
Now, that you have the new wheel circumference, what will happen to the number of rotations if the circumference of the tires were increased by 20%? Calculate the number of rotations for the new wheel. Divide 63,360/new circumference =_______rotations (Please only put the number as your answer)
The number of rotations for the new wheel will be 1,056 rotations
How to calculate the circumference of a wheel?Let the initial circumference be 50 rotations (assumed)
If the number of rotations of the circumference of the tires were increased by 20%, then the new circumference will be:
Ne circumference = 1.2 * 50 = 60
number of rotations for the new wheel = 63360/60
number of rotations for the new wheel = 1,056 rotations
Hence the number of rotations for the new wheel will be 1,056 rotations
