A college student goes to lunch at school and pays for lunch with her ID. Her mother put money into her account for her to do so, but she doesn’t know how much. Lunch is the same cost each day , but she doesn’t know what the cost is. After buying 4 lunches, she sees that her account balance is $91 . After buying 9 lunches , her balance is $67.25 .
Each lunch would cost 4.75
Yes, the relationship is linear.
The cost of each lunch is $2.639.
The initial amount deposited by her mother is $101.55.
What is the slope?The slope is the rate of change of the y-axis with respect to the x-axis.
The equation of a line in slope-intercept form is
y = mx + b, where
slope = m and y-intercept = b.
We know the greater the absolute value of a slope is the more steeper is it's graph or rate of change is large.
From the data itself, we can obtain two points to find the slope the points are
(4, 91) and (9, 67.25).
Slope(m) = (67.25 - 91)/(9 - 4).
Slope(m) = - 2.639.
The cost of each lunch is 2.639.
∴ 67.25 = -(2.639).9 + b.
b = 91.
∴ y = -(2.639)x + 91.
The initial amount put by her mother is 91 + 4(2.639) = $101.55

A dress which costs $59.95 has a decrease in price of 21%. Estimate the new price for this dress?
Answer:
46 Dollars
Step-by-step explanation:
New value =
59.95 - Percentage decrease =
59.95 - (21% × 59.95) =
59.95 - 21% × 59.95 =
(1 - 21%) × 59.95 =
(100% - 21%) × 59.95 =
79% × 59.95 =
79 ÷ 100 × 59.95 =
79 × 59.95 ÷ 100 =

Function f(x) represents the population of bacteria x hours after 9 a.m. What does F(2)-F(1) represent?
Answer:
f(2)-f(1) => Difference between the count of bacteria between 11AM and 10AM
Step-by-step explanation:
Here x is the number of hours after 9AM
f(2) means the count of bacteria after 2 hours of 9AM i.e. at 11AM
f(1) means the count of bacteria after 1 hour of 9AM i.e. at 10 AM
f(2) - f(1) will give us the difference between the count of bacteria between 11 AM and 10 AM
Hence,
f(2)-f(1) => Difference between the count of bacteria between 11AM and 10AM

The Sandoval family paid $180 for 2 adult tickets and 3 child tickets to an amusement park. The Martinez family paid $105 for 1 adult and 2 child tickets to the same park. What is the price of a child ticket?
Answer: The cost of a child ticket is $30
Step-by-step explanation:
Let's define the variables:
A = price of an adult ticket
C = price of a child ticket
We know that:
"The Sandoval family paid $180 for 2 adult tickets and 3 child tickets to an amusement park."
This means that:
2*A + 3*C = $180
and
"The Martinez family paid $105 for 1 adult and 2 child tickets to the same park."
This means that:
1*A + 2*C = $105
Then we have a system of equations:
2*A + 3*C = $180
1*A + 2*C = $105
To solve this, the first step is to isolate one variable in one of the equations, i will isolate A in the second equation:
A = $105 - 2*C
Now we can replace this in the other equation:
2*($105 - 2*C) + 3*C = $180
Now let's solve this for C, the price of a child ticket.
2*($105 - 2*C) + 3*C = $180
$210 - 4*C + 3*C = $180
$210 - C = $180
-C = $180 - $210
-C = - $30
C = $30
The cost of a child ticket is $30

A stack of 10 different cards are shuffled and spread out face down. If 3 cards are turned face up, how many different 3-card combinations are possible?
Answer:
120 different waysStep-by-step explanation:
Using the combination formula as shown;
nCr = n!/(n-r)!r!
If a stack of 10 different cards are shuffled and spread out face down. If 3 cards are turned face up, the number of different ways 3cards combinations are possible is expressed as;
10C3 = 10!/(10-3)!3!
10C3 = 10!/(7)!3!
10C3 = 10*9*8*7!/7!*3*2
10C3 = 10*9*8/3*2
10C3 = 720/6
10C3 = 120 different ways
Hence there are 120 different card combinations
The different 3-card combinations that are possible are; 120 possible combinations
This is a combination probability problem with the formula;
nCr = n!/((n-r)!r!)
Where;
n is sample size
r is possible choice
In this case;
n = 10
r = 3
Thus;
The different 3-card combinations possible are;
10C3 = 10!/((10 - 3)!3!)
>> 10!/(7! × 3!)
>> 120
Thus,there are 120 possible combinations of 3 different cards.

In 8 days, the temperature dropped 12 degrees. If the temperature changed at the same rate for all the days what was the change in temperature per day?
Answer:
1.5° per day
Step-by-step explanation:
Given that :
Total temperature change = drop by 12°
Number of days for the change = 8 days
Rate at which temperature changed is constant
Change in temperature per day :
Total change in temperature / number of days
12° / 8
= 1.5° per day

Answer:
Therefore, the line's equation and the correct slope will be:
[tex]y = 3, m = 0[/tex]
Therefore, option J is correct.
Step-by-step explanation:
As the line is perpendicular to the y-axis means the line is parallel to the x-axis.
i.e. m = 0As the line passes through (2, 3)so according to the point slop form
[tex]y-y_{1} =m(x-x_{1} )[/tex]
[tex]y - 3 = 0 (x - 2)[/tex]
[tex]y - 3 = 0 - 0[/tex]
[tex]y = 3[/tex]
Therefore, the line's equation and the correct slope will be:
[tex]y = 3, m = 0[/tex]
Therefore, option J is correct.

Answer:
2(x - 3) = 2x + 5
Multiply out the left side:
2x - 6 = 2x + 5
Subtract 2x from both sides:
-6 = 5
Since this is impossible, this "equation" cannot be solved.
