The vertical angles are equal to each other, that is, one of the one-sided corners will be 116°.

The sum of the one-sided angles is 180°, which means: 4x+116 = 180°

4x = 180-116 => 4x = 64°

x = 64/4 = 16°.

The sum of two adjacent angles is 180°. which means, that: 2x-3y = 180-64 = 116°

2x-3y = 116°

-2x+3y = -116

-32+3y = -116

3y = -116-(-32)

3y = -84

y = -84/3 => y = -28.

The reason for this is because to find the proportionality you divide the bottom number by the top and if one of the answer differentiates then it is not proportional with the rest of the table.

A company offers customers two plans for Internet service.

Plan A: $30 for the modem and $5 per month for service.

Plan B: $20 for the modem and $10 per month for service.


Equations:

Plan A: _______________

Plan B: _______________


BONUS: After how many months will both plans equal the same? _______________

Answers

Answer:

Step-by-step explanation:

lets say you are paying for a year

A- it would cost you $30 on the spot and another 60 for the year

A=30$60= $90

A-$30+($5*t)

B- it will cost you $20 on the spot then another 120 for the year

B-$20+($10*t)

B=$20+$120= $140

t= 12

plan A: 5x+30
plan B: 10x+20
bonus: the 2nd month

explanation for bonus:
5(2)+30
10+30
=40

10(2)+20
20+20
=40

the first month plan A would cost $35. plan b would cost $30 the first month. So, the earliest month both of them would cost the same price would be the second month.

Write a function rule for the output is 3 greater than 5 times the input.Use x for the independent variable and y for the independent variable

Answers

Answer:

hello sup

Step-by-step explanation:

Answer:
y = 6+3x
Step-by-step explanation:
If y = f(x), it means y is depending on x. This shows that y is the independent variable and x is the dependent variable.
y variable will be the output depending on the input variable x.
According to the function rule, “The output is 6 greater than three times the input." This can be expressed mathematically as 3x+6 (x being the input)
Three times the input = 3x
6 greater than three times the input = 6+3x
Since y is output then;
y = 6+3x
