Step-by-step explanation:

vertex of y=−|x+2|-1 is (-2 , -1), y ≤ -1

1. y>0     No x value will get y>0

2. y<0    x: real number -∞ -> ∞ get y value ≤ -1

3. y=0    No x value get y = 0

Which equation is not equivalent to 2x + 14 = 4x– 6

14 + 6 = 2x
-2x= 20
2x – 4x= -20
X = 10

Answers

First solve the equation
2x + 14 = 4x - 6
2x + 20 = 4x
20 = 2x, x = 10
See if any of the following has x = 10

Solution: -2x = 20
Because -2(10) = -20, so x isn’t 10

Answers

3 1/4is the correct answer
3 and 1/4 should be your answer.

the first thing you want to do is convert the 1/2 beside the 12 to 2/4ths so you can subtract the two fractions. your new equation would be 12 2/4 - 9 1/4. subtract 1/4th from 2/4ths and you'll get 1/4th. subtract 9 from 12 and you'll get 3.
your answer comes up as 3 and 1/4th.

How many degrees has (triangle)ABC been rotated counterclockwise about the origin?

Answers

Answer:

180°

Step-by-step explanation:

180

The total number of degrees in which has the triangle ABC been rotated counterclockwise about the origin is 180 degrees.

What is the rotation of the figure?

The transformation of a figure around a point, either clockwise or counterclockwise, is called rotation. A figure's coordinate point changes when it rotates.

About the origin, the triangle ABC has been rotated. The new triangle A'B'C' is created as a result. In the graph below,

The vertex B' points have the same but negative coordinates,

The vertex of B of the original figure points on the same line.

The coordinate point of B is (5,8).

The coordinate points of B' is (-8,-5).

The same will goes for the A and C points of the triangle

Thus the change in coordinate point after the rotation is,

coordinates of B = (5,8)

coordinates of B' = (-5, -8)

The same will follow with A and C

This is the rotation rule of 180 degrees counterclockwise.

Therefore, The triangle ABC has been rotated 180 degrees counterclockwise in all with respect to the origin.

Write the expression 5^2/3 without using exponents

Answers

The expression 5²/3 can be written without exponents as the fraction 25/3 or 8.33 approximately to 2 decimal place.

Whole numbers, exponents and fractions

Whole numbers include all natural numbers and 0 and can be expressed as exponents and fractions. Exponent is the method of expressing numbers in terms of powers while fractions a fraction represents a part of a whole or, more.

The expression 5²/3 having an exponent can be rewritten as follows:

5²/3 = (5 × 5)/3

5²/3 = 25/3

Therefore, without using exponents the fraction 25/3 or 8.33 approximately to 2 decimal place is the same as the expression 5²/3.
