Which equation has a missing number that is different from the others?
Answer:
732 + 100 = __
Step-by-step explanation:
732 - 100 = 632
732 + 100 = 832
732 = 632 + 100
732 - 632 = 100
linear equation in point slope form for a line that passes through the point (3,2) and has a slope of -4
Answer:
y = -4x + 14
Step-by-step explanation:
We'll use the slope intercept form: y = mx + b
It is given that the slope of -4, so m will be -4 like this: y = -4x + b
We are also given the coordinates where x = 3 and y =2
2 = -4(3) + b
2 = -12 + b
Add 12 to both sides
2 = -12 + b
+ 12 + 12
b = 14
We end up with y = -4x + 14

A catering company sells an 8 lb container of food for $54. Use a model to write a rate for this situation. What does this rate mean?
Answer:
$6.75 per pound
Step-by-step explanation:
$54 ÷ 8lb = $6.75/lb
or a 1:6.75 ratio/rate
The model to write the rate for this situation is 54 / 8 and the rate is $6.75.
What is Unit Rate?Unit rate is the amount of one quantity for a unit amount of the other quantity.
In other words it compares 1 unit of some quantity with different amount of another quantity.
Given that,
A catering company sells an 8 lb container of food for $54.
We have to find the unit rate for the given situation.
Price for 8 lb container of food = $54
Price for 1 lb container of food = 54 / 8
= $6.75
This is the required rate, which means that price for 1 lb container of food is $6.75.
Hence, the unit price for the food sold by catering company is $6.75.

Theo wants to use a cookie recipe that makes 36 cookies but he wants to reduce the number of cookies to 24. If the recipe specifies using 4.5 cups of flour, how much flour should he use?
Answer:
3 cups
Step-by-step explanation:
[tex]36 : 24 = 4.5 : x[/tex]
where [tex]x[/tex] is the amount of flour he should use
Therefore,
[tex]\frac{36}{24} = \frac{4.5}{x}[/tex]
Cross multiply: [tex]36x = 4.5 \times 24[/tex]
[tex]\implies 36x = 108[/tex]
Divide both sides by 36: [tex]x = 108 \div 36 = 3[/tex]
Therefore, he should use 3 cups of flour
Write an equation for a line parallel to y=-3x + 11 and goes through the point (2,4)
Answer:
equation: y = -3x + 10
Step-by-step explanation:
y = -3x + 11
comparing the formula, y = mx + b
We can determine the slope is -3 and y-intercept is 11.
if the line passes (2,4)
use the formula:
y - y1 = m(x - x1)
y - 4 = -3(x - 2)
y = -3x + 6 +4
y = -3x + 10

A city employee is organizing a race down Broadway, from Beale Street to Grand Avenue. There will be a water station at the beginning and end of the race. There will also be water stations along the route, with no more than one mile between stations. What is the minimum number of water stations for this race
It can be deduced from the multiplication that the minimum number of water stations for this race will be 28.
How to calculate the number of water stationsYour information isn't complete as the figures aren't provided. Therefore, an overview will be given.
In this case, let's assume that there are 14 routes and that there will be a water station at the beginning and end of the routes.
From the scenario, if the racers are to run through all the routes, the number of water stations will be the value of 14 multiplied by 2. This will be:
= 14 × 2 = 28
In conclusion, the correct option is 28.

A pool manager balances the pH level of a pool. The price of a bucket of chlorine tablets is $90, and the price of a pH test kit is $11. The manager uses a coupon that applies a 40% discount to the total cost of the two items. How much money does the pool manager pay for each item?
Answer:
The pool manager pay for each item is $60.6.
Step-by-step explanation:
Given:
A pool manager balances the ph level of a pool.
The price of a bucket of chlorine tablets is $90, and the price of a ph test kit is $11.
The manager uses a coupon that applies a 40% discount to the total cost of the two items.
Now, to find the money the pool manager pay for each item.
The price of a bucket of chlorine tablets is = $90.
The price of a ph test kit = $11.
So, to get the total price of both items we add both prices:
Total cost of two items = $101.
As, given a coupon that applies a 40% discount to the total cost of the two items.
Now, to get the total cost by applying discount:
Thus, the pool manager pay = $60.6.
Therefore, the pool manager pay for each item is $60.6.
During a winter storm, the temperature on the top of a
mountain changed an average of -2.5°C every hour
for 12 hours. At noon, the temperature was -5°C.
During the same time period, the temperature at the
bottom of the mountain changed at the rate of
temperature change on the top of the mountain.
What is the hourly rate of temperature change at the bottom of the mountain ?
According to the rate of change, it is found that the hourly rate of temperature change at the bottom of the mountain was of -2.5 ºC per hour.
What is the average rate of change?
The average rate of change of a function is given by the change in the output divided by the change in the input.
In this problem, it is stated that at the top of the mountain, the average rate of change is of -2.5 ºC per hour, and at the bottom of the mountain the rate is the same, hence the hourly rate of temperature change at the bottom of the mountain was of -2.5 ºC per hour.

2x - 7 = 5
Combine similar terms
2x = 5 + 7
2x = 12
x = 6
7(3x - 4) = 63
The first step is to divide both sides of the equation by 7
3x - 4 = 9
Combine similar terms
3x = 9 + 4
3x = 13
x = 4 1/3
6(3x + 3) = -72

3x + 3 = - 12
Combine similar terms
3x = -12 - 3
3x = -15
x = -5
-2(6x - 3) = 6

What is the area of this polygon
A=220 cm^2
A=242 cm^2
A=248 cm^2
A=270 cm^2
Answer:
A = 220 cm²
Step-by-step explanation:
Area of a rectangle = width x heightArea of a triangle = 1/2 x base x heightArea of the rectangle = 11 x 18 = 198 cm²
Area of the triangle = 1/2 x (18 - 7) x (15 - 11) = 22 cm²
Therefore, area of the polygon = 198 + 22 = 220 cm²
Answer:
220 is The Correct Answer
Letter Choice (A)
Step-by-step explanation:
HERE'S MY PROOF AND MY RESEARCH
Area of a rectangle = width x height
Area of a triangle = 1/2 x base x height
Area of the rectangle = 11 x 18 = 198 cm²
Area of the triangle = 1/2 x (18 - 7) x (15 - 11) = 22 cm²
Therefore, area of the polygon = 198 + 22 = 220 cm²

Write an equation for the function graphed below. I keep doing this and getting the same answer, what am I doing wrong.
Answer:
(-4(x-2))/((x+2)|(x-4)|)
Step-by-step explanation:
You were so close. I stared at your problem for a
long time when you first posted it. I used a graphing utility to experiment. Your denominator was perfect for getting the vertical asymptotes in the right place. The y-intercept worked. The x-intercept was exactly right. I couldn't get the far right piece of the curve to reflect down in the fourth quadrant.
Hours later...suddenly BAM! ABSOLUTE VALUE pops into my head.
I always thought the numerator should be negative, so that middle portion of the curve that looks like a cubic would start "up to the left" and end "down to the right" But those left and right curves should be like mirror images of each other sort of. So I tried the absolute value and it worked! Good luck with your work. Hope this helps a little.

Answer:
1/x+2
Step-by-step explanation:
1/x−2 + 4/4-X^2
Factor 4−x^2
1/x−2 + 4/(x−2)(−x−2)
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x−2 and (x−2)(−x−2) is (x−2)(−x−2).
Multiply : 1/x−2 TIMES −x−2/−x−2
−x−2/(x−2)(−x−2) + 4/(x−2)(−x−2)
Since −x−2/(x−2)(−x−2) and 4/(x−2)(−x−2) have the same denominator, add them by adding their numerators.
−x−2+4/(x−2)(−x−2)
Combine like terms in −x−2+4.
−x+2/(x−2)(−x−2)
Extract the negative sign in −x+2.
−(x−2)/(x−2)(−x−2)
Cancel out x−2 in both numerator and denominator.
