Using elimination method

bogdanovich [222]

Answer:

The value of x is 2 and y is (-5)

Step-by-step explanation:

<h3>Given;</h3>

-7x + y = – 19
-2x + 3y = – 19

The value of x and y

<h3>By Using Elimination Method;</h3>

First name the equation

-7x + y = – 19 ...(1)
-2x + 3y = – 19 ...(2)

Now, Multiply equation (1) by 3 we get,

3 × (-7x + y = – 19)

-21x + 3y = – 57

Now, Eliminate

-21x + 3y = – 57

-2x + 3y = – 19

+ – +

-19x = -38

x = -38/-19

x = 2

Now, Put the value of x in equation (2) we get the value of y.

-7x + y = – 19

-7(2) + y = – 19

-14 + y = -19

-14 + 14 + y = -19 + 14

y = -5

Thus, The value of x is (-5) and the value of y is 2.

<h3>For Verification;</h3>

-7x + y = – 19

-7(2) + (-5) = – 19

-14 – 5 = – 19

-19 = -19

-2x + 3y = – 19

-2(2) + 3(-5) = – 19

-4 – 15 = – 19

-19 = -19

Here, L.H.S = R.H.S

Hence Verified!

The paper scissors pencils stickers and paint belong on the top shelf of the craft closet.

Zolol [24]

Answer: The paper, scissors, pencils, stickers, and paint belong on the top shelf of the craft closet.

Explanation: When you are listing items, you need to place a comma in between them. The comma in between the “stickers” and “and” is the Oxford comma. When you lost multiple items, you need a comma after the word before “and”.

Plot the image of point C under a dilation about the origin (0,0) with a scale factor of 1/2

yuradex [85]

Answer:

See Attachment for graph

Step-by-step explanation:

Given

Point C

Required

Plot C when dilated by 1/2

First, we have to determine the coordinates of point C

From the attached graph;

$C = (0,6)$

Next, is to determine the new point when dilated;

This is calculated as thus;

$New\ Point = Old\ Point * Scale\ Factor$

$C' = (0,6) * \frac{1}{2}$

Expand the bracket

$C' = (0 * \frac{1}{2}, 6* \frac{1}{2})$

$C' = (0, \frac{6}{2})$

$C' = (0, 3)$

This implies that C' will be plotted at x =0 and y = 3

(See attached for point C')

16/20 =t + (- 13/20) help please what is t

Black_prince [1.1K]

Simplify brackets

16/20 = t + -13/20

Simplify 16/20 to 4/5

5/5 = t - 13/20

Add 13/20 to both sides

4/5 + 13/20 = t

Simplify 4/5 + 13/20 to 29/20

29/20 = t

Switch sides

t = 29/20

I need to know order pairs for this equation

kompoz [17]

Hi, you haven't provided the equation that you need order pairs for.

Therefore, I'll just explain how to find order pairs in general and you can apply the same method to the the equation you have

Answer with explanation:

Order pairs of any equation are (x,y) values that satisfy this equation

To get them, the simplest way is to assume a value for x, use this value to substitute in the equation you have and then solve for the corresponding y

Example:

Consider the equation: x + 2y = 8

at x = 0: 0 + 2y = 8 ............> 2y = 8 ..........> y = 4 ............> order pair is (0,4)

at x = 2: 2 + 2y = 8 ............> 2y = 6 ..........> y = 3 ............> order pair is (2,3)

at x = 4: 4 + 2y = 8 ............> 2y = 4 ..........> y = 2 ............> order pair is (4,2)

Now, we can say that (0,4), (2,3) and (4,2) are order pairs that satisfy the given equation

For your equation:

1- Assume value of x

2- Substitute with that value in the equation

3- Solve the equation for the corresponding y

4- The order par pair would be:

(assumed x value , corresponding calculated y value)

Hope this helps :)
