Answer:

x=2 y=4

Step-by-step explanation:

Answer:

(2,4)

Step-by-step explanation:

substitute the [tex]y = 2x[/tex] for the [tex]y[/tex] in [tex]x = -y + 6[/tex]

[tex]x = -(2x) + 6[/tex]

[tex]x = -2x + 6[/tex]

[tex]3x = 6[/tex]

[tex]x = 2[/tex]

next take [tex]x = 2[/tex] and input it into [tex]y = 2x[/tex]

[tex]y = 2(2)[/tex]

[tex]y = 4[/tex]

so if [tex]x =2[/tex] and [tex]y = 4[/tex], the ordered pair solution is:

[tex](2,4)[/tex]

How do you find the unknown side if you have the area and the other side?

Answers

Answer:

if you have the area (i'm assuming this is a square or rectangle) and one side, you can use division to find the other side

the formula for area is (side 1)(side 2) = area

so using this, divide the area by the side you do know, and you will get the unknown side

Answer:

$91/$15=x

Step-by-step explanation:

$100-$9=$91 and 91÷15= 6. omething which means only 6 pizza can be purchased.

The answer up above just says 91 divided by 15 gives you the amount of pizzas. He can only buy 6 pizzas with a pound remainding

Which coordinate plane shows triangle ABC after
a reflection over the y-axis?

Answers

After a reflection over the y-axis:
A=5
B=4
C=7

The rule for coordinates for a reflection over the y -axis is:

( x, y ) → ( −x, y )

The coordinates plane for the triangle ABC after a reflection over the y-axis is

A(5, -2), B(4, -4), and C(6, -4).

What is reflection?

Reflection is a transformation that flips a shape in a mirror line also called a line of reflection so that each point is the same distance from the mirror line as its reflected point.

The rule for coordinates for a reflection over the y -axis is:

( x, y ) → ( −x, y )

We have,

The following coordinates:

A = (-5, -2)

B = (-4, -4)

C = (-6, -4)

Since the rule for coordinates for a reflection over the y-axis is

(x, y) ⇒ (-x, y)

We have,

(-5, -2) = (5, -2)

(-4, -4) = (4, -4)

(-6, -4) = (6, -4)

Thus the coordinates plane for the triangle ABC after a reflection over the y-axis is A(5, -2), B(4, -4), and C(6, -4).

Find the horizontal distance between points C(3.5, −0.25) and D(0.5, −0.25).

Answers

Answer:

3 units

Step-by-step explanation:

Since the y-coordinate is the same. Therefore, there is a straight horizontal line between the two points. So, again, since the y-coordinates are the same, we can subtract C(x) (the x-coordinate for point C) from D(x) (the x-coordinate for point C)

C(x) = 3.5

D(x) = 0.5

3.5 - 0.5 = 3

Therefore, the distance between the two points is 3 units
