Answer:
Total=600+70(x)
The average cost of the phone is C(x) = (600 + 70x)/x.
How to calculate the average?In order to calculate average, divide the total sum of the data to the total number of data. An average is a standard number for a given data whose value can both be more or less than it.
Given that,
The fixed price of the cellphone is $600.
And, the monthly plan is $70.
Now, the cost of the phone increases with the number of months and the average cost is the total cost divided by the number of months.
As per the question the average cost can be written as,
C(x) = (600 + 70x)/x
Where x is the number of months.
Hence, the average cost of the given phone can be written in terms of the function of month as C(x) = (600 + 70x)/x.

If time is four hours from now, the time left till midnight would be quarter that if it is one hour from now. What time is it now?
Answer:
The time now is 7 pm
Step-by-step explanation:
Suppose that now is the time T.
We know that:
"if time is four hours from now, the time left till midnight would be a quarter that if it is one hour from now".
Then:
if we define midnight as 12, and we assume that T is in the pm range.
Then the "time left till midnigth, assuming that the time is four hours from now" will be written as (12 - (T + 4))
With this in mind, we can write the problem as:
12 - (T + 4) = (1/4)*( 12 - (T + 1))
Now we can solve this for T.
12 - T - 4 = (1/4)*(12 - T - 1)
8 - T = (1/4)*(11 - T)
4*(8 - T) = 11 - T
32 - 4*T = 11 - T
32 - 11 = -T + 4*T
21 = 3*T
21/3 = T
7 = T
Then T = 7 pm
The time now is 7 pm
(Inequalities) what do you have to do when multiplying or dividing by a negative number?
Answer:
When we multiply or divide by a negative to solve an inequality, it's the same as multiplying or dividing by a negative to solve a regular equation! Just remember to multiply or divide both sides by the same quantity, then simplify! Remember, when multiplying or dividing by a negative YOU MUST FLIP THE INEQUALITY SIGN.
Step-by-step explanation:
You are welcome.
And I hope this helps. :)
Answer:
Step-by-step explanation:
If you begin with an inequality and wish to solve for one of the variables, you must isolate that variable on the right side of a new inequality. Now supposing that that variable is negative in the given inequality, and that you must change that sign to positive. Generally you can either multiply every term in the given inequality by -1 or divide every term by -1. In both cases you must change the direction of the inequality sign.
Example: Given -3x > 2 + 5y, solve for x. To do this, multiply all three terms in the inequality by (-1/3), which yields x on the left and -2/3 - (5/3)y on the right. We must reverse the direction of the inequality sign, so the final answer is x < -2/3 - (5/3)y.
Regan has been saving her allowance for months, and she finally has enough to buy a new flat-screen TV! The TV's screen is shaped like a rectangle that is 50 inches wide. The screen's area is 1,500 square inches.
Answer:
The length of the tv is 30 inches
Step-by-step explanation:
area is LxW, so 50 x L = 1,500
L = 1,500/50
L = 30

The perimeter of the square is 64 inches. What is the perimeter of the shaded region?
Answer:
54.94 inches
Step-by-step explanation:
First you need to find the radius of the semi-circles within the square.
You find this by dividing the perimeter by 8
64/8 = 8
now use the formula πr^2 to find the area of the semi circle
π8^2 = 201.06
Now find the total area of the square and subtract it from the area of the two semi circles to find the shaded region
16*16 = 256
256-201.06 = 54.94

Step-by-step explanation:
please mark me branliest tyyyy!! :))))))))))
Answer:
[tex]y = \frac{1}{3} x-4[/tex]
Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of the given points into the formula and solve:
[tex]m=\frac{(-2)-(-3)}{(6)-(3)} \\m = \frac{-2+3}{6-3} \\m = \frac{1}{3}[/tex]
Thus, the slope is [tex]\frac{1}{3}[/tex].
2) Next, write the equation of the line using the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex]. (From there, we can convert it to slope-intercept form.) Substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.
Since [tex]m[/tex] represents the slope, substitute [tex]\frac{1}{3}[/tex] for it. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line intersects, substitute the x and y values of either one of the given points (it doesn't matter which one, it will equal the same thing) into the formula as well. I chose (3, -3), as shown below. From there, convert the point-slope form of the equation to slope-intercept form by isolating y:
[tex]y-(-3) = \frac{1}{3} (x-3)\\y + 3=\frac{1}{3} x-1\\y = \frac{1}{3} x-4[/tex]

jess solved the quadratic equation x^2+2x = 8 but made a mistake. her work is shown below. identify the step(s) in which a mistake was made
Answer:
x value would be 2
Step-by-step explanation:
The computation is shown below:
Given that
x^2 + 2x = 8
x^2 + 2x - 8 = 0
x^2 + 4x - 2x - 8 = 0
x(x + 4) - 2(x + 4) = 0
(x - 2) (x + 4) = 0
So, x value would be 2
x - 2 = 0
x = 2

Here is the complete question: Find the rate of change for the situation:
A chef cooks 9 lbs of chicken for 36 people and 17 lbs of chicken for 68 people.
Given: 1st situation, A chef cook 9 lbs chicken for 36 people.
2nd situation, chef cook 17 lbs chicken for 68 people.
∴ 1st situation, weight of chicken per person=
Weight of chicken per person=
2nd situation, weight of chicken per person=
Weight of chicken per person=
In both the situation chef cook same amount of chicken per person, which is
∴ Rate of change is
Step-by-step explanation:
There are several important information's already given in the question. Based on those information's the answer can be easily deduced.
In the first case,
The amount of chicken the chef cooks for 36 people = 9 pounds
Then
The amount of chicken the chef cooks for 1 person = 9/36
= 1/4 pounds
Now let us take the second case
The amount of chicken the chef cooks for 68 people = 17 pounds
Then
The amount of chicken the chef cooks for 1 person = 17/68
= 1/4 pounds
From the above deductions, it can be concluded that the correct option among all the options given in the question is the third option or option "B".
