This equation is a direct variation. If y increases, x increases. The constant of variation is 4 I think. Hope that helped.

The point (5, -3) is reflected over the y-axis. What is the x-coordinate after the reflection?

inn [45]

Answer:

-5

Step-by-step explanation:

Use a sheet a graph paper to assist you.

The original point (5,-3) reflected across the y-axis changes the x and y coordinates. 5 becomes -5 and -3 stays the same.

Which point is a solution to the linear inequality y < x 2? (2, 3) (2, 1) (3, –2) (–1, 3)

gayaneshka [121]

Alternative $1$

we have

$y < x+2$

we know that

If a point is a solution of the inequality

then

the point must be satisfy the inequality

we're going to verify all the points.

<u>case A)</u> point $(2,3)$

Substitute the value of x and the value of y in the inequality

$x=2\ y=3$

$y < x+2$

$3 < 2+2$

$3 < 4$ ------> is true

therefore

The point $(2,3)$ is a solution of the inequality

<u>case B)</u> point $(2,1)$

Substitute the value of x and the value of y in the inequality

$x=2\ y=1$

$y < x+2$

$1< 2+2$

$1 < 4$ ------> is true

therefore

The point $(2,1)$ is a solution of the inequality

<u>case C)</u> point $(3,-2)$

Substitute the value of x and the value of y in the inequality

$x=3\ y=-2$

$y < x+2$

$-2< 3+2$

$-2 < 5$ ------> is true

therefore

The point $(3,-2)$ is a solution of the inequality

<u>case D)</u> point $(-1,3)$

Substitute the value of x and the value of y in the inequality

$x=3\ y=-2$

$y < x+2$

$3< -1+2$

$3 < 1$ ------> is not true

therefore

The point $(-1,3)$ is not a solution of the inequality

Alternative $2$

we have

$y < x-2$

we know that

If a point is a solution of the inequality

then

the point must be satisfy the inequality

we're going to verify all the points.

<u>case A)</u> point $(2,3)$

Substitute the value of x and the value of y in the inequality

$x=2\ y=3$

$y < x-2$

$3 < 2-2$

$3 < 0$ ------> is not true

therefore

The point $(2,3)$ is not a solution of the inequality

<u>case B)</u> point $(2,1)$

Substitute the value of x and the value of y in the inequality

$x=2\ y=1$

$y < x-2$

$1< 2-2$

$1 < 0$ ------> is not true

therefore

The point $(2,1)$ is not a solution of the inequality

<u>case C)</u> point $(3,-2)$

Substitute the value of x and the value of y in the inequality

$x=3\ y=-2$

$y < x-2$

$-2< 3-2$

$-2 < 1$ ------> is true

therefore

The point $(3,-2)$ is a solution of the inequality

<u>case D)</u> point $(-1,3)$

Substitute the value of x and the value of y in the inequality

$x=3\ y=-2$

$y < x-2$

$3< -1-2$

$3 < -3$ ------> is not true

therefore

The point $(-1,3)$ is not a solution of the inequality

Without solving, determine whether the solution of x = 21 is greater than or less than 21. Explain.

astraxan [27]

Answer:

Without solving, the solution is greater than 21. The can be proven because a fraction of x is equal to 21, therefore x cannot be less than 21.

The correct answer will be marked as brainliest ! Please help me

Oksana_A [137]

The answer is D. It's always Rise over Run. So the slope would be 2/1 Or 2.
