Answer:
to find a y-value, plug in any number for x in the equation and then solve the equation for y.
if you're given a table that has x-values filled in, plug each of those in for x in order to solve for their corresponding y-value.
if the table is blank, pick whatever numbers you want to use as x-values. don't use any numbers that are astronomically large, though. i always find that the best, most basic numbers to stick with are -2, -1, 0, 1, and 2.
i hope this helps! have a lovely day <3
There are 80 people waiting to tour the science museum. The tour guide takes 4 groups of 16 people each. The remaining people will be in the last tour group. How many people are in the last tour group?
Answer:
16 people
Step-by-step explanation:
Given that :
Number of people to tour = 80
Number per group = 16
Number of groups = 4
Total number of people who make up the entire groups :
Number per group * number of groups
16 * 4 = 64
The number of people in the last tour group :
80 - 64
= 16 people

The sum of two numbers is 18, and the product of these two numbers is 56.
What are the numbers?
Answer:
-14 and -4
Step-by-step explanation:
x+y=18
xy=56 solving simultaneously, x=56/y
56/y + y = 18
What values of b satisfy 4(3b + 2)^2 = 64?
Answer:
The value of 0 can satisfy b.
Step-by-step explanation:
4(3b + 2)^2 = 64
(12b + 8)^2 = 64
(12b + 8)^2 = 64
144b + 64 = 64
144b + 64 - 64 = 64 - 64
144b = 0
144b / 144 = 0 / 144
b = 0
So, the value of 0 can satisfy b.
Answer:
b = [tex]\frac{2}{3}[/tex] or b = -2
Step-by-step explanation:
4(3b + 2)^2 = 64
Divide by 4 on both sides
(3b + 2)^2 = 16
Square root both sides
√(3b + 2)^2 = √16
3b + 2 = ±4
Subtract 2 on both sides
3b = ±4 - 2
Divide by 3 on both sides
b = (±4 - 2)/3
If 4 is positive, b is [tex]\frac{2}{3}[/tex]
If 4 is negative, b is -2
The grade of a hill is its steepness represented as a percent. Jin tracks his walking speed up different hills. What does the rate of change, or slope, represent in this situation?
A scatterplot with grade of hill as a percent on the x axis and walking speed in miles per hour on the y axis. About 20 points are plotted in a downward trend along with a line of best fit which begins at the point zero comma 3 point 5 and passes through the point 2 comma 3.
The rate represents an increase in speed for each 1% grade increase.
The rate represents a decrease in speed for each 1% grade decrease.
The rate represents a decrease in speed for each 1% grade increase.
The rate represents no change in speed for each 1% grade decrease.
Answer:
the speed decreases for every 1% grade decreases

A triathlete swims 3 km in 1 hr. Then bikes 50 km in 3 hrs. Finally, the triathlete runs
12 km in 1 hr. What is the triathlete's average speed? Show how you got your answer.
Answer:Let $d$ be the length of one segment of the race.
Average speed is total distance divided by total time. The total distance is $3d$, and the total time is $\frac{d}{3}+\frac{d}{20}+\frac{d}{10}=\frac{29d}{60}$.
Thus, the average speed is $3d\div\left(\frac{29d}{60}\right)=\frac{180}{29}$. This is closest to $6$, so the answer is $\mathrm{(D)}$
Can you give me the answer and how you got the answer if that’s possible
ax^2+bx+c is the first degree polynomial of x which of these letters equal zero?
First degree polynomials means that the maximum power x is raised up to that does not have a coefficient 0 is 1. And here we have a term ax^2 which means it could not be a first degree polynomial if a has a positive or negative value. Thus, letter a in this case should be 0 in order for this to be a first degree polynomial of x.

Mai bought 3 pairs of socks and 2 pairs of shoes. A pair of shoes costs one dollar less than 5 times the price of a pair of socks. She spent $56.50. How much does a pair of socks cost and how much does a pair of shoes cost? (use one varible)
Answer:
Cost of a pair of socks = x = $4.5
Cost of a pair of shoes = y = $21.5
Step-by-step explanation:
Let us represent
Cost of a pair of socks = x
Cost of a pair of shoes = y
Mai bought 3 pairs of socks and 2 pairs of shoes.
She spent $56.50.
Hence:
3x + 2y = 56.50
A pair of shoes costs one dollar less than 5 times the price of a pair of socks.
y = 5x - 1
Hence, we substitute 5x - 1 for y
3x + 2y = 56.50
3x + 2(5x - 1) = 56.5
3x + 10x - 2 = 56.5
13x - 2 = 56.5
13x = 56.5 + 2
13x = 58.5
x = 58.5/13
x = $4.50
Solving for y
y = 5x - 1
y = 5(4.5) - 1
y = 22.5 − 1
y = $ 21.5
Cost of a pair of socks = x = $4.5
Cost of a pair of shoes = y = $21.5

(05.03 LC) The equation shows the relationship between x and y: y = 7x + 2 What is the slope of the equation? (5 points) −7 −5 2 7
Answer:
The slope of the equation is the final option listed: The slope is 7.
Step-by-step explanation:
In a y = mx + b equation, b represents the slope. So, whatever 'b' is, that's the slope. In this equation, we have y = 7x+2, so that means that the slope is 7. It also means that the y-intercept is 2. I'll attach a photo that helps!

A shoe store paid the manufacturer $27.00 for a new pair of basketball shoes. If the store sells the basketball shoes for $60.75, what is the percent mark-up?
Answer
125% markup
Step-by-step explanation:
Hope this helps :)
The percentage markup the store has made is 125%.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, A shoe store paid the manufacturer $27.00 for a new pair of basketball shoes.
The store sells basketball shoes for $60.75.
So, Amount markup is $(60.75 - 27.00) = $33.75.
∴ The percentage markup is (33.75/27)×100%.
= 125%

The mode is the most common number in the data set. If there are two numbers that appear frequently (in this case 69 and 73) then this data set has two modes.
The median is the middle of the set of numbers (line them up from top to bottom).
In this case it should look something like:
68 68 69 69 69 69 70 70 71 72 72 73 73 73 73 75 78
If the whole list of numbers are even, then pick the two middle numbers and find their average. If it is odd, just choose the middle most number.
Mean is the average of all numbers. If you have 5 numbers, add them all up and divide by 5. If you have 10 numbers, add them all up and divide by 10.

Im having a d ^ mb moment whats 2 and a half hours minus 30 minutes?
Answer:
2 hours.
Step-by-step explanation:
2 and a half hours is 2.5 hours.
30 minutes is 0.5 hours.
2.5 - 0.5 = 2 hours.
Answer:
2 hours (I know I'm late but I like to answer things TvT)
Step-by-step explanation:
2 hours can be converted into 120 minutes (60 mins in an hour, 60 x 2 = 120)
120 minutes plus the half hour (30 mins) equals 150 minutes.
150 minutes minus 30 minutes equals 120 minutes, so 2 hours is your answer.

What is the value of x in the equation? (X+6)=-18 -36 -33 0 – 24 0 -18
Answer:
x = -24
Step-by-step explanation:
Equation Solving
Solve:
x + 6 = -18
We must isolate the variable x on the left side. To do that, we subtract 6 from both sides of the equation:
x + 6 - 6 = -18 - 6
The 6's cancel out. Operating on the right side:
x = -24
