Mikey solved the inequality problem below incorrectly. Explain her error and redo the problem showing the correct answer.
Original problem: -4x+8<32


Mikey’s math work: -4x+8-8<32-8
-4x÷-4<24÷-4
x<-6

Answer:

The answer would be B!

Step-by-step explanation:

To find which expression is equivalent, do the distributive property.

A. 1/5 * 4x = 4/5x

    1/5 * 1/1 = 1/5

4/5x + 1/5  <--- This is wrong!

B.  2/5 * 2x = 4/5x

    2/5 * 3/1 = 6/5 = 1 1/5

4/5x + 1 1/5 <--- This is correct!

C. 4/5 * x = 4/5x

    4/5 * 2/1 = 8/5

4/5x + 8/5 <--- This is wrong!

D. 5/4*x = 5/4x

    5/4 * 1/1 = 5/4

5/4x + 5/4 <--- This is wrong!

Therefore, the answer is B!  Hope this helps!

Answer: 60% increase followed by a 40% decrease belongs in less than original. A 50% increase followed by a 33 1/3 decrease also belong in less than original. A $20 decrease followed by a $20 increase belongs in same as original. A 75% decrease followed by a 50% increase belongs in less than original. A 100% increase followed by a 33 1/3 decrease belongs in less than original.

Answer:

Graph A represents a function

Step-by-step explanation:

in a function every input will have its own specific output.

Answer:

When you are finding a line that is perpendicular, you need to look at the slope. In the format, y=mx+b, the m represents the slope. In this case, the slope (m) of the line is -1/9. A line with a perpendicular slope is the negative inverse. The negative inverse for -1/9 is 9/1. Once you know the slope, you can begin to plug in the new information in order to find the new b (y intercept).

New Line information:

m=9/1, (2,-5) --> this means that x = 2 and y = -5

y=mx+b

-5 = 9/1(2) + b

-5 = 18 + b

-23 = b

Once you find the b, you plug the b and m into the equation y = mx + b

y = 9/1x -23

Answer:

A and the slope is -7/6

Step-by-step explanation:

First start at the first point -2, -3 and go down until you hit -4 the y coordinate of point 2 which will be -7 and move your finger right and count how many squares you go. 6.  The first one is the numerator and the second one is the denominator 6.  -7/6

Answer:

D

Step-by-step explanation:

All living organisms are made up of one or more cells, which are considered the fundamental units of life. Even unicellular organisms are complex! Inside each cell, atoms make up molecules, which make up cell organelles and structures. In multicellular organisms, similar cells form tissues.

Answer:

D) All organisms are made of cells

Answer:

73

Step-by-step explanation:

7^2 = 49

Order of operations, parenthesis first.

3*4 = 12

5*12 = 60

49+60 = 109

6^2 = 36

109-36 = 73

Answer:

1.) 73

2.) x+x+x+y+y = 2y + 3x

2(x+2y) = 2x + 4y

x+x+y+y = 2x + 2y

Answer:

N= -5/8=0.625

Step-by-step explanation:

2.1      Solve  :    -8n-5 = 0  

Add  5  to both sides of the equation :  

                     -8n = 5

Multiply both sides of the equation by (-1) :  8n = -5

Divide both sides of the equation by 8:

                    n = -5/8 = -0.625

Answer:

144ft^2

Step-by-step explanation:

Two shapes in this figure, trapezium and rectangle.

Trapezium area formula: 1/2 x (sum of bases) x Height

Rectangle area formula: length x breadth

Figure area:

Trapezium area: 1/2 x sum of bases x height

Trapezium area: 1/2 x (5+12.4) x 8

Trapezium area: 1/2 x 17.4 x 8

Trapezium area: 69.6

Rectangle area: length x breadth

Rectangle area: 12.4 x 6

Rectangle area: 74.4

Area of complete figure: Area of trapezium + Area of rectangle

Area of complete figure: 69.6 + 74.4

Area of complete figure: 144ft^2

Hope it helps you!!!!
