if each two complementary angles has the same measure, then each angle will equal what?
Answer:
ok
Step-by-step explanation:
it's ammmmmmmmmmmmmmmmmmmmmost doen
=====================================================
Work Shown:
Let x be the measure of each of the two angles (which is valid because they both have the same measure). Since they are complementary, the angles add to 90
So,
x+x = 90
2x = 90
x = 90/2
x = 45
Each angle is 45 degrees
45+45 = 90

A satellite radio company charges a one time fee of $36 for installation. The company also charges $42 per month for use. based upon this information complete this table showing the total cost of using the satellite radio after each month listed.
Answer:
Table shown below
Step-by-step explanation:
Linear Modeling
It consists of finding and using the equation of a line to represent the behavior of a real situation in numerical terms.
We are given the model of the charges for a satellite radio company that charges a fixed fee of $36 for installation and a variable fee of $42 per month for use.
The model is written as:
C(m) = 36 + 42m
Where m is the number of months.
For m=1:
C(1) = 36 + 42(1)=$78
For m=2:
C(2) = 36 + 42(2)=$120
For m=3:
C(3) = 36 + 42(3)=$162
For m=4:
C(4) = 36 + 42(4)=$204
For m=5:
C(5) = 36 + 42(5)=$246

In the equation, f(x)=2x-4(x+1), what is the value of f(-14)?
A. 32
B. -32
C. 5
D. 24
Answer:
D. 24
Step-by-step explanation:
Plug in -14 to the equation:
f(x) = 2x - 4(x + 1)
f(-14) = 2(-14) - 4(-14 + 1)
Simplify:
f(-14) = -28 - 4(-13)
f(-14) = -28 + 52
f(-14) = 24
So, D is the correct answer.

Answer:
You can use the formula for the perimeter of a square to find the length of one of the square's sides. Then substitute that information into the formula for the area of a square and solve.
Step-by-step explanation:
Taking the exam same as you 90 % sure this is right
The area of the square can be gotten by using the perimeter of the square to get the length of the square. Then, we use the length to find the area of the square.
Properties of a square.All the sides are equalAll the angles are equal.All the sides are parallel to each other.Therefore,
perimeter of a square = 4l
where
l = length of squareTherefore,
4l = 20
divide both sides by 4
l = 20 / 4
l = 5 meters
Therefore,
area of the square = l²
where
l = side lengtharea of the square = 5²
area of the square = 25 cm²

Answer:
The friends split the bill at 15.32$
Step-by-step explanation:
So to find how much each paid you would take the bill total and divide it by the amount of people in this case three
And for the equation it would be 45.96/3=15.32$
The equation to model the solution to the problem would be; 3x = 45.96. the friends split the bill at 15.32 dollars.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables. A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be one degree.
Given that the dinner for Lorenzo and his 3 friends costs $45.96.
To determine how much each paid would take the bill total
Therefore, we will divide it by the number of people in this case three
3x = 45.96
x = 45.96/3
x = 15.32$
And for the equation would be; 3x = 45.96

find an equation for line L
Explanation:
Line L is the horizontal line. Any point on this line has y coordinate y = 4, so the equation is simply y = 4.
You could say the equation is y = 0x+4, which shows the slope is 0. But I think y = 4 is the better answer.
