Answer:

Option C has correct equations.

Step-by-step explanation:

Given that:

x + 2y = 2 ---------eq1

-4x + 4y = -8 ---------- eq2

eq2 can also be written after taking 2 common as

-x + y = -2 ----------- eq3

Now by adding eq 1 and eq3 we get:

3y = 0

y=0

putting value of y in eq1

x + 0 = 2

x = 2

So the solution set = (2 , 0)

Now by putting values in equations of option C:

x + 2y = 2

2 + 2(0) = 2

2 = 2 (satisfied)

5x - 2y = 10

5(2) - 2(0) = 10

10 = 10 (satisfied)

i hope it will help you!

This is an urgent message, help me and get 30 points and brainiest answer!

GaryK [48]

The initial value is where the line intersects the y-axis. So, this does it at y = 2. The graph has a slope (rate of change) of 1, because for every x-value, the y-value goes up by exactly 1. So, the answer is C.

There are 4 sports stores,9 clothing stores and 6 jewelry stores ina shopping crnter which ratio compares the number of sports s

Pani-rosa [81]

The ratio is 2 : 9

Step-by-step explanation:

Given:

The number of sports store = 4

The number of clothing store = 9

The number of jewellery stores = 5

To Find :

The ratio of number of sports stores to the total number of stores

Solution:

The ratio of number of sports stores to the total number of stores

= $\frac{\text{number of sports store}}{\text{ Total number of stores}}$

The total number of stores = number of sports store + number of clothing store + number of jewellery store

The total number of stores = 4 + 9 + 5

The total number of stores = 18

Now the ratio is

= $\frac{4}{18}$ or 4 : 8

The ratio after reduction is

= $\frac{2}{9}$ or 2 : 9 or 2 to 9
