The slope is the cost of Hana's lunch.
C.
The y-intercept is the cost of one book.
D.
The y-intercept is the cost of Hana's lunch.
Answers
Answer:
A and D
Step-by-step explanation:
I took it and I got it correct
The true statements are the slope is the cost of one book and the y-intercept is the cost if Hana's lunch.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
As, from the graph the slope tells us about the cost of one book.
Now, From the graph if we talk about y- axis then we can see that the y- axis tells us about cost if Hana's lunch.
Hence, the true statements are the slope is the cost of one book and the y-intercept is the cost if Hana's lunch.

A salt water solution is cooled to −6° C. During an experiment, the mixture is heated so that its temperature rises at a steady rate. Write an equation to represent the temperature, y, after x minutes.
Answers
Answer:
y = -6 + xt
where t is the rate of rising of the heated mixture per minute
Step-by-step explanation:
From the question, we are lacking an important input. This is the value of the steady rise in temperature. In other terms, this is the rate at which the temperature of the mixture rises per minute.
Let this constant rate be t ° C. What this means is that it rises by this temperature in a minute.
in 1 minute, the temperature rise is t, in two minutes it will be 2t.
Then in x minutes, it will be xt
So adding the initial temperature of minus 6, the equation will be;
y = -6 + xt
An underground mine elevator descends 12% of the total depth every minute. The total depth of the elevator is 75 meters below the ground. How many meters below the ground is the elevator after 2 minutes?
Answers
Answer:
18m below the groundStep-by-step explanation:
"An underground mine elevator descends 12% of the total depth every minute. The total depth of the elevator is 75 meters below the ground. How many meters below the ground is the elevator after 2 minutes?"
We want to estimate the depth after certain number of time
Given
total depth=75m
rate of descends =12% of total depth
= 12/100*75= 0.12*75
=9 meters per minute
Therefore in 2 minutes we can use the expression to find the distance/depth
speed= distance/time
9=distance/2
distance=9*2
distance= 18 meters
Therefore the elevator is 18m below the ground in 2 minutes
Answer:
18 meters

Brylee has hiked 125 feet and hikes 1 foot per second. Jeremiah has hiked 10 feet and hikes 3.5 feet per second. After how many seconds will Brylee and Jeremiah have hiked the same amount of feet?
Answers
Answer:
46 seconds
Step-by-step explanation:
Brylee has hiked 125 feet and hikes 1 foot per second.
125 + s
Jeremiah has hiked 10 feet and hikes 3.5 feet per second.
10 + 3.5s
Where
s = number of seconds
Equate both Brylee and Jeremiah expression
125 + s = 10 + 3.5s
Collect like terms
125 - 10 = 3.5s - s
115 = 2.5s
Divide both sides by 2.5
s = 115 / 2.5
= 46
s = 46 seconds

In the diagram below, which distance represents the distance from point Q to
RS?
Answers
Answer: QT
Step-by-step explanation: This is because line QT is a straight line, in which it leads from point Q to line RS. QT is true because any other lines have angles, which add more (inaccurate) distance.
The required representation of distance from point Q to RS is QT.
What is a line?
A line is a straight distance connecting two points or more showing the shortest distance between the initial and final points.
here,
A figure is shown with a line segment RS and a point is located some distance from line RS, denoted as Q. It is to be determined which represents the distance from point Q to RS.
The shortest distance between a point and a line is the perpendicular line drawn from the point to the line, so QT is the representation of the measure of the distance from point Q to RS.
Thus, the required representation of distance from point Q to RS is QT.

A parent invests $2000 at a 5% interest rate to help his daughter save for college. How long will it take his money to double?
Answers
Answer: 20 years
Step-by-step explanation:
Principal = $2000
Rate = 5%
Interest = $2000
Time = Unknown
Since we want to know the time it will take his money to double, that means he'll have an interest of $2000.
Interest= PRT/100
2000 = (2000 × 5 × T)/100
2000 = 10000T/100
Cross multiply
2000 × 100 = 10000T
200,000 = 10000T
T = 200,000/10,000
Time = 20 years

If they have 20 pounds of strawberries to freeze.If they put 1.25 pounds of strawberry would in to each freezing container how many containers will they fill
Answers
Answer:
They will fill 16 containers
Step-by-step explanation:
From the question,
They have 20 pounds of strawberries to freeze and they put 1.25 pounds of the strawberry into each freezing containers.
To determine how many freezing containers they will fill, we will divide the total mass of strawberries they have by the mass of strawberry they put into each freezing containers.
Hence,
Number of containers they will fill = Total mass of strawberries that have / Mass of strawberry they put into each container
Total mass of strawberries that have = 20 pounds
Mass of strawberry they put into each container = 1.25 pounds
∴ Number of containers they will fill = 20 pounds / 1.25 pounds
Number of containers they will fill = 16
Hence, they will fill 16 containers.

The following image was reflected over the x-axis. What are the coordinates of C’?
Answers
Answer:
C' is (6,3)
Step-by-step explanation:
Since the new image was reflected over the x-axis, the x-coordinate would be the same as the orginial, it wouldn't change. The only thing that would change is the y-coordinate. The image has to be the same distance away from the original, so that means the y-coordinate would be the opposite sign. Reflecting the image over the x-axis would put it in quadrant one, so the y-coordinate would have to be positive.
