Answer:

  an infinite number

Step-by-step explanation:

The left side of the equation is a restatement of the right side of the equation. It is true for all values of x. There are an infinite number of solutions.

Answer:

x= 77

Step-by-step explanation:

The angle at 122 degrees is a linear pair with the isosceles triangle, meaning it makes 180 degrees.

180-122= 58 degrees

Since it is an isosceles triangle, the two angles at the bottom are both 58 degrees.

Let's use this info to find the degree at the top.

58+58= 116

There are 180 degrees in a triangle, so subtract 116 degrees we have so far to find the last angle.

180-116= 64 degrees

And since the angle at the top makes 90 degrees, we can subtract 64 degrees to find the smaller angle to the right of the 64 degree angle.

90-64= 26 degrees

And since a triangle has a total of 180 degrees, subtract the 26 degrees from 180.

180-26= 154 degrees.

And since it is an isosceles triangle, divide the remaining 154 degrees by 2 because they are both equal.

154/2= 77 degrees.

Your answer is 77 degrees.

A tray contains 16 chocolate chip cookies and 12 oatmeal raisin cookies. HOw many ways can a child select 3 cookies that include
pishuonlain [190]

Answer:

Number of ways chosen cookies = 8 ways

Step-by-step explanation:

Given;

Total number of chocolate chip cookies = 16

Total number of oatmeal raisin cookies = 12

Total number of cookies choose = 3

At least 1 chocolate cookie

Find:

Number of ways chosen cookies

Computation;

Number of total ways = 2³

Number of total ways = 8

If at least on cookie is chocolate cookie,

Number of ways chosen cookies = Number of total ways - 1

Number of ways chosen cookies = 9 - 1

Number of ways chosen cookies = 8 ways

(MC 02.03) If parallelogram ABCD was reflected over the y-axis, reflected over the x-axis, and rotated 180°, where would point A
Soloha48 [4]

A' would lie on point A (-4 , 1)

Step-by-step explanation:

Let us revise some transformations

1. If point (x , y) reflected across the x-axis , then its image is (x , -y)

2. If point (x , y) reflected across the y-axis , then its image is (-x , y)

3. If point (x , y) rotated about the origin by angle 180°, then its image

    is (-x , -y)

Parallelogram ABCD was reflected over the y-axis, reflected over the

x-axis, and rotated 180°

We need to know where would point A' lie

∵ The coordinates of point A are (-4 , 1)

∵ The parallelogram is reflected over x-axis

∴ The sign of y-coordinate of point A changed to opposite

∴ The image of point A is (-4 , -1)

∵ The parallelogram then reflected over the y-axis

∴ The sign of x-coordinate of point (-4 , -1) changed to opposite

∴ The image of point (-4 , -1) is (4 , -1)

∵ The parallelogram then rotated 180°

∴ The signs of the x-coordinate and the y-coordinate of point (4 , -1)

   changed to opposite

∴ The image (4 , -1) is (-4 , 1)

∴ A' is (-4 , 1)

∵ Point A is (-4 , 1)

∴ A' would lie on point A

A' would lie on point A (-4 , 1)
