Answer 2
Answer:

｡☆✼★ ━━━━━━━━━━━━━━  ☾  

2x + 5y = 19

x - 2y = -4

Multiply the second equation by 2

2x - 4y = -8

Now we have:

2x + 5y = 19

2x - 4y = -8

Subtract the second eq from the first to get:

9y = 27

/ 9

y = 3

Now substitute this value into one of the first equations

x - 2(3) = -4

x - 6 = -4

x = 2

Thus, your answer would be option B

Get the equation to slope-intercept form: y = mx + b

6x + 3y = 6

Subtract 6x from both sides. This will give you 3y = -6x + 6.

Then, divide by 3 on both sides. This gives you y = -6x + 2.

2 is your y intercept and -6 is your slope.
Positive 6x is is subtracted on the left side, which in turn is moved to the right side. As 3y = -6x + 6 another way of saying this would be the inverse of 6x = -6x.

Please Help! Determine which relation is a function.

Answers

To find the function,

draw a vertical line through every point. If there is no other point lies on this line, then this is a function.

If we do this vertical line test,

in the first graph, there are two points at (-1, -1) and (-1, 3) lie on the same line and therefore, it is not a function.

In the second graph, points at (-2, -2) and (-2, 1) lie on the same line and therefore, it is not a function.

In the third graph, points at (0, -1) and (0, 2) lie on the same line and therefore, it is not a function.

In the fourth graph, in each vertical line, only one point lies and hence it is a function.
The answer is D because it is the only one which no two points on top of each other.

Dakota’s mom made two pies for Thanksgiving, a pumpkin pie and a pecan pie. The pictures show the remaining slices in each pie in gray. What portion of the pies did Dakota’s family eat on Thanksgiving?
A) 3/8

B) 5/8

C) 1 3/8

D) 1 1/2

Answers

The portion of the pies Dakota’s family ate on Thanksgiving is 5/8. Therefore, option B is the correct answer.

The given pictures show the remaining slices in each pie in gray.

What is the fraction?

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Number of slice ate in pumpkin pie = 2/8

Number of slice ate in pecan pie = 3/8

Total number of slice pie ate

= 2/8+3/8

= 5/8

The portion of the pies Dakota’s family ate on Thanksgiving is 5/8. Therefore, option B is the correct answer.

For #12 and #13, make a function table of values for each function with the given input values.#12: y=5x-1 for x=4, x=12,x=0 and x=0.5
#13: y=1.7x, for x=5, x= -5, and x=100
Please show work and thanks for helping

Answers

#12. When x = 4, y = 5(4) - 1 = 20 - 1 = 19
         when x = 12, y = 5(12) - 1 = 60 - 1 = 59
         when x = 0, y = 5(0) - 1 = 0 - 1 = -1
         when x = 0.5, y = 5(0.5) - 1 = 2.5 - 1 = 1.5

5 ÷ x for x = 1/3 solve

Answers

So if x is equal to 1/3, then our equation would be 5/(1/3). When dividing by a fraction, you can multiply by the reciprocal to find the answer, meaning that if you divide by 1/3, you can multiply by 3/1. So your answer would be 15.
5/(1/3)=x
5*3=x
15=x
