Point A, located at (-11, - 7) on the coordinate plane, is reflected over the x-axis to form point B. Then point B is reflected

hram777 [196]

Answer:

<em>Answer: B(-11,7) C(11,7)</em>

Step-by-step explanation:

<u>Reflections In The Coordinate Plane </u>

Reflect over the x-axis:

When we reflect a point over the x-axis, the x-coordinate remains the same, but the y-coordinate is mapped to its opposite.

The reflection of the point (x,y) over the x-axis is the point (x,-y).

Reflect over the y-axis:

When reflecting a point over the y-axis, the y-coordinate remains the same, but the x-coordinate is mapped to its opposite (its sign is changed).

The reflection of the point (x,y) across the y-axis is the point (-x,y).

Point A is at (-11,-7). When reflected over the x-axis, it maps to Point B located at B(-11,7).

Point B is now reflected over the y-axis and maps to C(11,7).

Answer: B(-11,7) C(11,7)

Joe worked 12 hours and packed 32 cartons. Bob worked 25 hours and packed 64 cartons. Did Joe and Bobwork at the same rate?O YES

Bas_tet [7]

To be able to compare the rates, we will write them in fraction form.

The fraction that represents Joe's rate is:

$\frac{32}{12},$

and the fraction that represents Bob's rate is:

$\frac{64}{25}\text{.}$

Simplifying the above fractions, we get:

$\begin{gathered} \frac{32}{12}=\frac{8}{3}, \\ \frac{64}{25}=\frac{64}{25}\text{.} \end{gathered}$

Since:

$\frac{8}{3}\ne\frac{64}{25}$

then Bob and Joe did not work at the same rate.

Answer:

No, Bob and Joe did not work at the same rate.

Find the approximate area of the triangle y x> O 30 square units O 15 square units 21 square units 45 square units

Fiesta28 [93]

Answer:

Step-by-step explanation:

a right triangle is half of a rectangle and the area of a rectangle is

area of rectangle = length × width

Area of a triangle is one half times the length times the width

area of triangle = 1/2 × length × width

in this case

length is the number of the y units

width is the number of x axis unit

area of triangle = 1/2 × length × width

area of triangle = 1/2 × (y units) × (x units) you need to count and insert

the number of units into the

equation

area of triangle = 1/2 × (??? y units ) × (??? x units ) do the math yourself

and see if you get one of
