Step-by-step explanation:
Can someone help me please?
Answer:
1. m = 3x
2. Possibly doesn't have a constant rate of change, because if you were to multiply 4.9 to the other coordinates/points/x values provided, you would not get the correct value for y, this means that the rate of change is not constant. Not only that but if you are to find a value that can multiply and add up to each, it would not go with the first coordinate.
3. The constant rate of change is found to be: m = 0.375
Step-by-step explanation:
In the question, it is asking for the constant rate of change.
This can be found determined by the graphs:
x | y
5 | 15
8 | 24
12 | 36
24 | 72
From what is shown, on x's side, we can see that:
5 · 3 = 15
8 · 3 = 24
12 · 3 = 36
24 · 3 = 72
This means that the constant for the first graph is m = 3x.
x | y
2 | [tex]\frac{3}{4}[/tex]
4 | [tex]1\frac{1}{2}[/tex]
6 | [tex]2\frac{1}{4}[/tex]
8 | 3
If you change the fractions into decimals:
[tex]\frac{3}{4}[/tex] = 0.75
[tex]1\frac{1}{2}[/tex] = 1.5
[tex]2\frac{1}{4}[/tex] = 2.25
= 3.00
(The change is + 0.75)
0.75 + 0.75 = 1.5
1.5 + 0.75 = 2.25
2.25 + 0.75 = 3.00
(But what about multiplying it?)
It is found that 0.75 DOES NOT work with muliplying, BUT we can find the rate of change if we divide 0.75 by 2
[tex]\frac{0.75}{2}[/tex] = 0.375
This would be your rate of change!

Matea recorded that water levels in one part of the river fell 1.05 millimeters per year for 2.48 years. Describe how you could estimate the total variation in water level
Answer:
The decrease of the decimal rate -1.05 mm/year can be rounded to -1. You don’t need to round 2.48 because you’re multiplying by -1. Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6.
Step-by-step explanation:
Answer:
The decrease of the decimal rate -1.05 mm/year can be rounded to -1. You don’t need to round 2.48 because you’re multiplying by -1. Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6.
Step-by-step explanation:
If you don't want to use that answer this is what they are looking for
Round -1.05 mm/year to –1.
Estimate the total variation as (-1)(2.48) = -2.48 mm.
Because -1.05 is negative and rounded to a greater value, adjust the estimate to -2.5 or -2.6 millimeters

if there are 208 ducks in the lake and there are 499 more duck that want to join. But the lake can only fit 250. How would they get all the ducks in how big does the lake need to be. Explane your answer.
hello, there are 208 ducks, there are 449 more ducks who want to come to the lake 208 + 499 = 707 total ducks The maximum number of ducks this lake can buy is 250.
formula = total ducks - total number of ducks it can afford = calculates how big the lake can be.
so 707-250 = 457

Jake, Becky, and Max are meeting at Charley's Pizza for dinner and then plan to go to a movie. When they arrive at the pizza place, each one of them has a different coupon. They decide to use the coupon that will give them the best deal. Jake's coupon is $19.99 for a pizza and pasta meal deal; Becky's coupon is for two large one-topping pizzas--each at of the menu price; and Max's coupon is for three medium one-topping pizzas -- each at off the menu price. According to the menu, a medium one-topping pizza is $8.99, and a large one-topping pizza is $14.89. They also spend $1.25 each for sodas and $5.00 on the tip. At the movie theater, Max has a coupon that's good for off a third movie ticket when you purchase two other movie tickets at the regular price. The regular price of each movie ticket is $9.80.
Although Jake, Becky, and Max plan to split the cost of the pizza and movie, they decide that with the coupons, it's just easier if one of them pays at each place. So, the friends agree that Jake will pay for the pizza and Becky will pay for the movies. At the end of the night, they'll figure out how much Max owes both Jake and Becky.
If Jake gives the server $30 at the pizza place, he should receive back ______
$1.50 in change (after leaving the tip).

2. Mr. Andrew wants to give each of his students an equal number of the crayons he bought. There are 32 students in Mr. Andrew’s class. How many crayons will each student get?
Estimate first.
Solve the problem and explain your answer using pictures, diagrams, equations, and/or words.
3. How many more boxes of crayons does Mr. Andrew need if he wants each of his students to get 12 crayons? Explain your answer.
Answer:
Step-by-step explanation:
2.
Because we don't know how many crayons he bought we will call it c.
c = total number of crayons purchased
T = total number of crayons each student gets
To determine how many crayons each student gets we divide c by 32, because that's the number of students in his class.
c / 32 = T
So let's say he purchased 120 crayons.
c = 120
120/32 = T
T = 3.75
Since he can't give a fraction of a crayon, in this case, each student will get 3 crayons.
3.
We will now pretend there are 24 crayons in 1 box.
So T still equals the total number of crayons each student gets and c still equals number of crayons purchased, but now we also have b which equals the number of crayons in 1 box.
c = total number of crayons purchased
T = total number of crayons each student gets
b = number of crayons in 1 box
x = number of boxes purchased
So b*x = c
We can still write the equation:
c / 32 = T
We know T = 12 So we plug 12 in for T
c / 32 = 12 Now multiply each side by 32, so 32 will cancel on the left.
32c/32 = 12 * 32
c = 12 * 32
c = 384
So if he needs to purchase 384 crayons we can use our other equation.
b*x = c
b = 24
c = 384
So we plug those in.
24x = 384 Divide each side by 24 so 24 will cancel on the left.
24x/24 = 384/24
x = 384/24
x = 16
So he needs to buy 16 boxes of crayons in this instance. We can figure out how many boxes he bought in #2 by using the same equation.
b*x = c
c = 120 in #2
b =24
24 * x = 120
24x/24 = 120/24
x = 120/24
x = 5
So for each student to have 12 crayons he needs to purchase 11 more boxes (16 - 5 = 11).
This will work for whatever numbers you were given.
Remember:
c = total number of crayons purchased
T = total number of crayons each student gets
b = number of crayons in 1 box
x = number of boxes purchased
b*x = c
c / 32 = T

East Middle's football team was positioned on the 50 yard line. After a penalty is called, the football team is pushed back 5 yards. If East Middle's football team is charged with the same penalty 3 plays in a row, on what yard line is the football team positioned?
A. 65 yard line
B. 35 yard line
C. 25 yard line
D. 15 yard line
Answer:
The answer would be the 35 yard line.
Step-by-step explanation: This is because if they get a 5 yard penalty 3 times, that would be a total of 15 yards lost. So, you would do 50-15, getting 35, so boom, 35 yard line :)
