Answer:

[tex]2y + 8 = 4 \\ 2y = 4 - 8 \\ 2y = - 4 \\ y = \frac{ - 4}{2} \\ y = - 2 \\ y + 1 = - 2 + 1 \\ \boxed{y + 1 = - 1}[/tex]

Therefore, the value of (y+1) is -1

12x - 4=4(2x+1) What is x?

Answers

Answer:

x = 2

Step-by-step explanation:

12x - 4 = 4(2x + 1)

Distribution first

12x - 4 = 4(2x) + 4(1)

12x - 4 = 8x + 4

Isolate x to one side

12x - 4 - 8x = 8x - 8x + 4

12x - 8x - 4 = 4

4x - 4 = 4

4x - 4 + 4 = 4 + 4

4x = 8

4x/4 = 8/4

Continuous graph:

- The height of a plant as it grows

- Amount of fuel and distance traveled.

Discrete graph:

- Number of students per teacher

- Amount of chairs for each table

Step-by-step explanation:

In mathematics "discrete" means specific points that do not possess a continuous line but only the plotting of points above certain integer values. On the other hand, the word "continuous" in mathematics would be a graph that has a constant smooth line that lacks jumps between values and sometimes decimal numbers.

"The number of students per teacher" would be discrete as the amount of students per teacher would be a fixed integer value.

"The height of a plant as it grows" would be continuous as the height of the plants increases the longer it grows. This would be represented by a straight continuous line.

"Amount of fuel and distance traveled" would be continuous as the amount of fuel used correlates with the distance traveled, which can be represented with a continuous line.

"Amount of chairs for each table" would be discrete as it would be a set integer value for the amount of chairs at each table, not a continuous line.

x = 1, x = -1
x = 1x = -7
x = -1, x = 7​

Answers

Answer:

x = 1, x = -7

Step-by-step explanation:

Step 1: Divide both sides by -2.

[tex]\frac{-2(|4x+12|)}{-2} = \frac{-32}{-2}[/tex] [tex]|4x + 12| = 16[/tex]

Step 2: Solve absolute value.

We know either 4x + 12 = 16 or 4x + 12 = -16.

1st Possibility:

4x + 12 = 164x + 12 - 12 = 16 - 12 (Subtract 12 from both sides)4x = 44x/4 = 4/4 (Divide both sides by 4)x = 1

2nd possibility:

4x + 12 = -164x + 12 - 12 = -16 - 12 (Subtract 12 from both sides)4x = -284x/4 = -28/4 (Divide both sides by 4)x = -7

Therefore, the answer is x = 1, x = -7.

Answers

Answer:

20cm

Step-by-step explanation:

1. First find the area of the triangle

a = 1/2 × base × h

a = 1/2 × 10 × 11

a = 55cm²

2. Then times the area of the triangle by 8 to find the area of the rectangle

55 × 8 = 440cm²

3. Find the width of the rectangle:

The area of a rectangle is = l × w

22 × width = 440cm²

width = 440 ÷ 22

width = 20cm

Answer: Width = 20

Step-by-step explanation:

Give the area of triangle = x

So the area of rectangle = 8x

the area of triangle = (11 × 10) ÷ 2 = 55

So the area of rectangle = 8(55) = 440

The area of rectangle = W × L

So 440 = W × 22

W = 20
