Answer:

x=3

y=1

Step-by-step explanation:

First, get x and y on the left in the lower equation. -2x+10y=4. Then solve using a calculator. Select (apps), PlySmlt2, Simultaneous EQN Solver, and enter your euqations in.

Answer:

(3, 1)

Step-by-step explanation:

I will show the strategy of elimination in my solution, you can use other strategies but I will use elimination.

Line up variables:

4x - 3y = 9

10y = 2x + 4 -> -2x + 10y = 4

Multiply by 2 for elimination:

-4x + 20y = 8

Now we can add the equations together:

17y = 17

y = 1

Since we know that y is 1, we can plug that into an equation in the system and see what x is.

4x - 3 = 9

4x = 12

x = 3

x = 3

y = 1

Check our answer:

12 - 3 = 9 - Correct

10 = 6 + 4 - Correct

Exspress the ratio from the simplest form 72:36

Vedmedyk [2.9K]

First, find the GCF. For these two numbers, it is 36. (Because 36 times 1 is 36 and 36 times 2 is 72)
Divide both sides by this, which gives you a
2:1 ratio

Which functions are symmetric with respect to the y axis<br>

Inessa05 [86]

Answer:

A, B, and D

Step-by-step explanation:

Only the functions that have x by itself between the absolute value signs (A, B, and D) are symmetric with respect to the y-axis .

Placing a constant outside the absolute value signs moves the function up or down the y-axis but retains the symmetry.

Adding a constant inside the absolute value signs (as in C and E) moves the axis of symmetry to the left or right of the y-axis.

In the diagram, both A and B are symmetric with respect to the y-axis, but C has been shifted three units to the left.
