Answer:

a. Infinitely many solutions

Step-by-step explanation:

The given equations are 2x - y = 3

4x = 6 + 2y

We can use substitution method to solve these system of equations.

2x - y = 3

y = 2x - 3

Now plug in y = 2x - 3 in the second equation, we get

4x = 6 + 2(2x - 3)

4x = 6 + 4x - 6

4x = 4x

Here we get infinitely many solution.

Both the equations are the same.

Thank you.

Each side of a quilt square measures approximately 4.25 inches. If there are about 2.54 centimeters in 1 inch, how long is each

IrinaK [193]

Answer: approximately 10.8 centimeters

Step-by-step explanation:

We have a square, where each side measures approx. 4.25 in

Now we know that 1in ≈ 2.54 cm

Then, in 4.25 in, we have 4.25 times 1 inch, so we have 4.25 times the length of 2.54 cm

So the approximate measure of the sides in centimeters is:

4.25*(2.54)cm = 10.8 cm

So we have that each side measures approximately 10.8 centimeters

Point A located at -11 and -7 on the coordinate plan is reflected over the X axis to form point B.Then point B is reflected over

Diano4ka-milaya [45]

Answer:

The coordinates of B are (-11,7)

The coordinates of C are (11,7)

Step-by-step explanation:

Reflection of Points

Given a point (x,y), it can be reflected in several ways. Two of the most-used are reflection over the x-axis and reflection over the y-axis.

When the point is reflected over the x-axis, the x-coordinate is unchanged, and the y-coordinate is inverted: (x,y) -> (x,-y).

When the point is reflected over the y-axis, the y-coordinate is unchanged, and the x-coordinate is inverted: (x,y) -> (-x,y).

Point A is located at (-11,-7). It's reflected over the x-axis to form point B whose coordinates are (-11,7).

Then, point B is reflected over the y-axis to form point C with coordinates (11,7).

The coordinates of B are (-11,7)

The coordinates of C are (11,7)
