Answer:
y=3x
Step-by-step explanation:
Equation is y=mx+b
Slope is 3/1 or 3x.
Y-intercept is at the origin or (0,0), so you take the y-coordinate.
Plug them into the equation.
y=3x+0 or y=3x

Answer:
Stefan should rent a phone accessory store
Step-by-step explanation:
The given information are;
The total of the estimated income and expenses are given as follows;
Sales
Type [tex]{}[/tex] Amount [tex]{}[/tex] Frequency
Sales [tex]{}[/tex] $ 950 [tex]{}[/tex] Each week
Services [tex]{}[/tex] $2,875 [tex]{}[/tex] Each month

Travel [tex]{}[/tex] -$7.50 [tex]{}[/tex] Each day
Merchandise [tex]{}[/tex] -$1,650 [tex]{}[/tex] Each month
Therefore;
Total sale = 4×950 = $3,800
Total services = $2,875
Total income = $3,800 + $2,875 = $6,675
Total expenses = $4,500 + $7.50×30 + $1,650 = $6,375
Total profit = Total income - Total expenses = $6,675 - $6,375 = $300
Therefore, the net profit = $300.
Therefore, given that Stefan is able to make a net profit from his investment, he should rent a phone accessory store.

Nile had 20% less strikeouts this year than last year. He had 124 strikeouts last year. Which steps are needed to calculate the number of strikeouts Nile had this year? Check all that apply
(A) Convert 20% to a decimal.
(B) Multiply: 0.2 × 124 = 24.8
(C) Divide: 124 ÷ 20 = 6.2
(D) Subtract: 124 – 24.8 = 99.2
(E) Add: 124 + 24.8 = 148.8
(F) Subtract: 124 – 6.2 = 117.8
Answer:
(A) Convert 20% to a decimal.
(B) Multiply: 0.2 × 124 = 24.8
(D) Subtract: 124 – 24.8 = 99.2
Step-by-step explanation:
Given parameters:
Number of strikeouts last year = 124
Percent reduction = 20%
Unknown:
Number of strikeouts this year =?
Solution:
To find the number of strikeout this year,
Convert 20% to a decimal = [tex]\frac{20}{100}[/tex] = 0.2
Now; Multiply: 0.2 × 124 = 24.8
The number of strikeouts this year = 124 - 24.8 = 99.2

Respect to time as a line. What is the slope of line?
Please help !
Answer:
it is C
Step-by-step explanation:
i took all the test and got a hundred
if we graph his distance with respect to time as a line then slope of line is 45.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Arturo after 3 hours of driving is 135 miles from home. After 5 hours of driving, he is 225 miles
from home
Let the two points are (3, 135) and (5,225)
m=225-135/5-3
=90/2
=45
Hence, if we graph his distance with respect to time as a line then slope of line is 45.

Answer:
468
Step-by-step explanation:
and this is how you spell answers
The value of 78 × 6 is 468
What is multiplication?Multiplication is the process of calculating the product of two or more numbers. The result of multiplication is called product.
If a × b = c , this means that a and b are the factors and c is the product.
For example if each student has 5 apples and there are 100 students in the camp, the total number of apples in the camp is
100 × 5 = 500 mangoes.
Similarly, 78 × 6
= 70 × 6 + 8 × 6
= 420 + 48

A different store needs to make at least $20,000 to make a profit in March. They average $685 a day for the month. James used rounding and estimation to say, "$685 is almost $700. $700 × 30 days is $21,000. I think it is going to be a close call!" What do you think?
Answer: James is right
Step-by-step explanation:
Since they average $685 a day for the month. This means for the month, they'll make:
= $685 × 30
= $20,550
Approximating $20,550 will give $21000 and since James used rounding and estimation to say, "$685 is almost $700 and $700 × 30 days is $21,000. James is quite correct.

19: 1 1/2= 1.5, 1 1/3= 1.3 (3 is repeated)
Explanation:
To start with, you need to convert the fractions into decimals in order to compare them easier
Then, for the negatives, it might be confusing but the bigger negative will be smaller since it's further away from 0 on a number line
Also, for #19, obviously, the negatives go first but for 0.5 and 0.55, it's kinda hard to compare but for 0.5, just add a zero at the end to extend the decimal and compare it. It would become 0.50 and 0.55 would then clearly be greater.

I need help please.
Answer:
10. y=the total amount of money
A) y=4m
B) y= 4(5.25)
y= $21
11. y= total amount of money
A) y= 40m + 35
B) y= 40(10) + 35
y= $435
Number 10:
You know five people, you and four friends, are contributing the same amount of money for food. Lets say F = Food and M=Money. Since they are contributing the same amount of money, it would be 5 * m, or 5m. So, F would equal 5m. F=5m.
Part B- You would do the same expression, F=5m, but you would instead plug 5.25 in for m. So, 5.25 times 5 would equal 26.25 dollars.
Number 11:
Part A- Let M equal months. $40 times the number of months + 35 is the total cost, so 40m +35 is the expression.
Part B- Since the total cost is 40 dollars times the number of months + $35, you would multiply 40 * 10, to get 400 dollars over 10 months. Then you would add the $35 fee, so the answer would be $435.
Convert y = x2 - 4x + 1 to vertex form by completing the square.
O y= (- 1)2 + 4
O y= (1 - 2)2 +5
O y= (x - 2)2 – 3
O y = (x - 4) + 1
Answer:
vertex: (-2, -3)
Step-by-step explanation:
y = x2 + 4x + 1
y = x2 + 4x + 22 + 1 - 22
y = (x + 2)2 + 1 - 4
y = (x + 2)2 - 3 in y = (x - h)2 + k, (h, k) is the vertex.
Answer:
y = (x - 2)² - 3
Step-by-step explanation:
Given
y = x² - 4x + 1
To complete the square
add/subtract ( half the coefficient of the x- term )² to x² - 4x
y = x² + 2(- 2)x + 4 - 4 + 1
= (x - 2)² - 3

We need to add -1 to each side of this to get rid of the -1 in the equation.
2x - 1 + 2 = 2
2x + 1 = 2
We need to subtract 1 from each side.
2x = 1
x = 0.5

2(0.5) - 1 + 2 = 2
1 - 1 = 0 + 2 = 2 (Checks out)
ANSWER: x = 1/2The weight, y, in pounds, of kittens was tracked for the first 8 weeks after birth where t represents the number of weeks after birth. The linear model representing this relationship is ŷ = 1.7 + 1.48t. Statler wanted to predict the weight of a kitten at 10 weeks. What is this an example of, and is this method a best practice for prediction? Explain your reasoning.
Answer:
Step-by-step explanation:
The mentioned relationship for the weight, in pounds, of the kitten with respect to time, in weeks, is
[tex]\hat y =1.7 +1.48t[/tex]
Weight of the kitten after 10 weeks
[tex]\hat y =1.7 +1.48\times 10[/tex]
[tex]\hat y =16.5[/tex] pounds
This modeled equation is based on the observation of the early age of a kitten where the kitten is in its growth period, but in the early stage the growth rate in the weight of the kitten was the same but the growth of any living beings continues till the adult stage. So, after some time, in real life situation, this weekly change in weight will become zero, So, this model is not suitable to measure the weight of the kitten over the larger time period.
Here, t= 10 weeks is nearby the observed time period, so the linearly modeled equation can be used to predict the weight.
Hence, the weight of the kitten after 10 weeks is 16.5 pounds.
