For part one, this means that the y value (the second value) is -8, and since we know that y=3x-2, we can say that -8=3x-2.
Adding 2 to both sides using the addition property of equality, we get -6=3x. Next, dividing by 3 using the division property of equality, we get -2=x. Therefore, plugging -2 in the point, we get (-2,-8) as our point.

For the second point, we have 2 as the x value, so we can plug that into 3x-2 to get 3*(2)-2=6-2=4 as the y value, making the point (2,4)

First you will have too find the least common multiple which is 20 and what you multiplied to get 20 multiply it which will make 3/5 to 12/20 and 1/4 too 4/20 and then subtract the two which is 8/20 or 8 oranges. if you need more information talk too me

I NEED HELP PLEASE ! :)
dedylja [7]

We can write a proportion to resemble the problem;

AE/ED = AB/BC

AE = 9

ED = 6

AB = x

BC = 10

Substitute with the given values.

9/6 = x/10

9/6 * 10 = x/10 * 10

90/6 = x

15 = x

Therefore, the answer is 15.

Best of Luck!

Please i need help.....
Lina20 [59]

Answer:

A.105°

Step-by-step explanation:

Angle at W and V are equal and the angles at T and U are also equal

Hence taking angles at T and U...so as to calculate the value of x

5x + 15 = 3x + 21

5x - 3x = 21 - 15

2x = 6.....hence, x = 3

Then for the angle of VXU;

All angles in a triangle add up to 180°

15(3) + 3(3) + 21 = 75°...then subtract from 180°..so as to obtain angle at VXU

180 - 75 = 105°

Suppose the function F(c) represents the earnings of a volleyball team from selling c cupcakes. They are selling each cupcake fo
navik [9.2K]

Answer:

The variable c represents the domain as it is the independent variable.

The domain of the function F(c) is given by c ≥ 0.

So, only positive values for the input make sense.

The upper limit of the domain is +∞ and lower limit is 0.

It is not possible for the team to earn $50.50 as it will be only multiple of 2.

Step-by-step explanation:

If F(c) represents the earning of a volleyball team from selling c cupcakes and each cupcake costs $2 each, then the equation that models the situation is  

F(c) = 2c ..... (1)

The variable c represents the domain as it is the independent variable. (Answer)

The domain of the function F(c) is given by c ≥ 0. (Answer)

So, only positive values for the input make sense. (Answer)

The upper limit of the domain is +∞ and the lower limit is 0. (Answer)

It is not possible for the team to earn $50.50 as it will be only multiple of 2. (Answer)
