The following machine doubles each input, subtracts 3, and then squares the result. (check photo) For example, if we input 5, then double 5 to get 10, subtract 3 to get 7, and finally square 7 to get 49.
-Write the expression that comes out of the machine if the input is 4.
Use ^ to express exponents. For example. 3² = 3^2

Phil has a three-year contract for his cell phone service. He pays $572.60 each year to cover everyone and his family. How much will the cell phone service cost over the three-year period
Answer:
$1717.80
Step-by-step explanation:
We are given one clue: He pays $572.60 each year to cover everyone and his family.
We are asked to find how much does Phil have to pay after 3 years. So, we must multiply 572.60 by 3 to find the total cost Phil has to pay after 3 years.
572.60 x 3 = Total cost to pay after 3 years.
=> $1717.80 = Total cost to pay after 3 years.
We can conclude that Phil will have to pay $1717.80 after 3 years.

Answer:
A 65
Step-by-step explanation:
x = -5
y = -8
-5 - 5 (-8)^2 / -5 = -325 / -5
= 65
Answer:
65
Step-by-step explanation:
So, this expression is asking us to solve an equation when x = -5 and y = -8.
When asked to solve problems like this, all we have to do is plug in the numbers accordingly
[tex]\frac{x-5y^2}{x} ---->\frac{(-5)-5(-8)^2}{(-5)}[/tex]
Now, we can simplify using PEMDAS
[tex]\frac{-5-5(64)}{-5} = \frac{-5-320}{-5} = \frac{-325}{-5} = 65[/tex]

The FAA tracks average flight delays. It found that, last year, a particular airline had an average flight delay of 20 minutes. So far this year, the airline has an average that is 45% shorter. What is the current year's average?
Answer:
11 minutes
Step-by-step explanation:
45% of 20 can be found by multiplying 20 and 0.45
which equals 9
so if the average delay was 20 but is now 9 minutes shorter then the current year's average is 11 minutes
The average delay in the current year is 11 minutes.
Given that, last year, a particular airline had an average flight delay of 20 minutes.
This year the airline has an average that is 45% shorter.
We need to find what is the current year's average.
What is average?In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Now, 45% of 20=45/100×20=9
So,20-9=11
Hence, the average delay in the current year is 11 minutes.

what is the x-intercept of a line that passes through the point (3,4) and has a slope of 2?
Answer:
(1,0)
Step-by-step explanation:
Hi there!
We want to find the x intercept of the line that passes through the point (3,4) and has a slope of 2
First, let's find the line
We are given both a slope, and a point. We can write the equation of the line in point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point
We do have everything needed to write the equation, let's just label everything to avoid confusion:
m=2
[tex]x_1=3[/tex]
[tex]y_1[/tex]=4
Now substitute those values as the variables that they represent into the equation:
[tex]y-y_1=m(x-x_1)[/tex]
y-4=2(x-3)
Now we have the equation in slope-point form
The x intercept of the line is the value in which the line passes through the x axis. The value of y at this point is 0
So we can substitute y as 0 in the equation to find out the value of x:
y-4=2(x-3)
0-4=2(x-3)
Multiply
0-4=2x-6
Add 6 to both sides
0+2=2x
Simplify the left
2=2x
Divide both sides by 2
1=x
So the value of the x intercept is 1, also written as the point (1,0)
Hope this helps!

What is the lateral surface area of this rectangular prism?
Answer: 208 in^2
5/9 + 1/3 × 1/3 = 0.66666666666 = 2/3
Step-by-step explanation:
The prime factorization of 100,000 is 2^5 × 5^5. Since it has a total of 10 prime factors, 100,000 is a composite number.
-----------------------------------------------------------------------------------------------------
5.8-0.2=4+0.2−0.2
5.6 = 4x
5.6/4 = 4x/4
x= 1.4
-----------------------------------------------------------------------------------------------------
Square sides are equal..
A=a^2=1.1^2≈1.21
-----------------------------------------------------------------------------------------------------
The lateral surface area of a rectangular prism can be calculated by finding the sum of all the lateral faces of the prism, i.e. the total area excluding the area of the bases. The formula to find the surface area of a rectangular prism is given as, Lateral surface area of a rectangular prism = 2(l + b) h square units.
When a prism has its bases facing up and down, the lateral area is the area of the vertical faces. (For a rectangular prism, any pair of opposite faces can be bases.) The lateral area of a right prism can be calculated by multiplying the perimeter of the base by the height of the prism.

If you earn both hourly wages and a commission at your job, your gross wages, w, can be calculated with the following equation:
cs + rh = w
where c is your commission rate, s is your total sales in dollars, r is your hourly rate, and h is your hours worked.
Solve for s to rewrite the equation for total sales.
The equation that is used to represent (s) the total sales is s = (w - rh)/c
An equations is used to show the relationship between two or more variables.
Given the equation:
cs + rh = w
To solve for s, we have to make s the subject of the equation:
cs + rh = w
subtract rh from both sides:
cs + rh - rh = w - rh
cs = w - rh
Divide both sides by c:
cs/c = (w - rh)/c
s = (w - rh)/c
The equation that is used to represent (s) the total sales is s = (w - rh)/c

Answer:
When rotating a point 90 degrees counterclockwise about the origin our point A(x,y) becomes A'(-y,x). In other words, switch x and y and make y negative. When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative.
