It is a function because –40°C is paired with –40°F.
It is a function because every Celsius temperature is associated with only one Fahrenheit temperature.
It is not a function because 0°C is not paired with 0°F.
It is not a function because some Celsius temperatures cannot be associated with a Fahrenheit temperature.

In the diagram, which two angles must be supplementary with angle 6?

NEED ANSWER ASAP
4 lines intersect to form 16 angles. The angles created, clockwise from top left are 1, 2, 3, 4; 5, 6, 7, 8; 13, 14, 15, 16; 9, 10, 11, 12.
Angle 5 and Angle 7
Angle 1 and Angle 10
Angle 14 and Angle 16
Angle 7 and Angle 11

Answers

i believe it’s 5 and 7

The two angles must be supplementary with angles 6 will be angle 5 and 7.

What is mean by Angle?

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

⇒ 4 lines intersect to form 16 angles.

And, The angles created, clockwise from top left are 1, 2, 3, 4; 5, 6, 7, 8; 13, 14, 15, 16,

Here, two combinations of angles 5 and 7 are having a sum of 180 degrees with angle 6.

So, The supplementary angles to angle 6 are angle 5 and angle 7.

Thus, The two angles must be supplementary with angles 6 will be angle 5 and 7.

Answer:

For the first one, you get x<7.

For the second one, you get x >_ 11

Step-by-step explanation:

For the first one: -2x - 2 > -16

Step 1. Add 2 to both sides.

-2x - 2 +2 > -16 + 2

-2x > -14

Step 2. Divide both sides by -2 and switch the sign

-2x/-2 > -14/-2

x < 7

For the second one: 2x - 1 >_ 21

Step 1: Add 1 to both sides

2x -1 +1 >_ 21 + 1

2x >_ 22

Step 2: Divide both sides by 2

2x/2 >_ 22/2

Carlos has $45 in his lunch account. He spends $2.25 each day on lunch, d. Elijah has $50 in his lunch account. He spends $2.50 each day on lunch, d. The two boys used all the money in their lunch account on the same day. Which equation could be used to determine the number of lunches each boy was able to purchase with the amount of money they had in their account?

Answers

Answer:

$45.00 divided by $2.25 or $50 divided by $2.50

Step-by-step explanation:

because this would determine the unit rate. Which is how many lunches the had. They had the total of Carlos would get 20  Elijah would also get 20. They would have an even amount of meals the paid for.

Answer:  Carlos had 4 day to eat lunch before his money ran out and Elijah also had four day so they both got 8 meal in total.

Step-by-step explanation: it they both got breakfast and lunch each day then that make four day to eat and also just do 2.25 time 5 day of school then divide the sum of what you got by $45 you should get 4 as for Elijah do 2.50 time 5 day of school then divide $50 by what your sum should be and you also get 4 day for him

see watch and  learn

2.25 time 5= 11.25

$45 divided by ll.25=4

2.50 time 5=12.5 or 12.50

$50 divided by 12.50=4 too

Josh is comparing the cost of having his car wash plus filling up his tank with gas at each business. How many gallons of gas would he need to purchase for the cost to the same at each car wash?

Answers

The first one is 6 gallons and the other one you can’t because if josh gets 3 gallons of gas he’s going to have to pay $8.25 but if he gets 4 gallons he’s going to have to pay $11
Josh would need to purchase 9 gallons of gas at the Quik-Clean car wash and 10 gallons of gas at The Mighty Clean Car wash. 15+(2.50x9)=37.50
