4x -5 = 2(2x +1)
I need help

Answers

Answer 1

Answer:

No Solution

Step-by-step explanation:

[tex]4x-5=2\left(2x+1\right)[/tex]

Expand:

[tex]4x-5=2* \:2x+2* \:1[/tex]

[tex]4x-5=4x+2[/tex]

Add 5 to both sides:

[tex]4x-5+5=4x+2+5[/tex]

[tex]4x=4x+7[/tex]

Subtract 4x from both sides:

[tex]4x-4x=4x+7-4x[/tex]

[tex]0=7[/tex]

No solution as this is false.

alejandro william scored 13 goals last season. he scored 5 more goals this season than last season than last season. how many goals did he score this season

Answers

Answer:

18 goals this season.

Step-by-step explanation:

First, we must identify what the question is asking.

13 goals last season, 5 more this season.

How many this season?

Well, if he scored more this season, we know this is going to be an addition problem.

Since he scored 13 last season a 5 more this season, we must add 13 and 5.

13 + 5 = 18 :D

Answer:

18 goals this season

Step-by-step explanation:

Well we are trying to find the answer to this season.

If he scored more goals than last season (13), you will need to add.

13+5= 18

Answers

Answer:

the answer is b

Step-by-step explanation:

edge 2020

The function with the greatest constant of variation is function B, x: 1, 2, 3, 4, y: 3.2, 6.4, 9.6, 12.8.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The constant of variation (k) is calculated as k = Δy/Δx for two points on a line.

For Function B, k = (6.4 - 3.2)/(2 - 1) = 3.2, which is the greatest constant of variation among all the functions.

For Function A, x: 8, 9, 10, 11, y: 20, 22.5, 25, 27.5, k = (22.5 - 20)/(9 - 8) = 1.25.

For Function C, on the coordinate plane C, a line goes through points (0, 0) and (3, 1), k = (1 - 0)/(3 - 0) = 1/3.

For Function D, on the coordinate plane D, a line goes through points (0, 0) and (1, 2), k = (2 - 0)/(1 - 0) = 2.

blThe mean height of the corn plants of variety A is 43.8 inches. Interpret the value of the mean in the
situation.

Answers

Answer:

The average inches of the height of the corn plants of variety A is 43.8 inches

Step-by-step explanation:

In mathematics or statistics, the mean refers to the average of numbers.

The mean is estimated by dividing sum of all the numbers by the count of the numbers.

For this question, the mean height of the corn plants of variety A of 43.8 inches is obtained as follows:

Sum of all the inches = 46 + 46 + 47 + 48 + 49 + 49 + 50 + 6 + 48 + 49 = 438 inches

Count of all the inches = 10

Mean = Sum of all the inches / Count of all the inches = 43.8 inches

The interpretation of this is that the average inches of the height of the corn plants of variety A is 43.8 inches.

Answers

Answer:

No solutions / "no"

Step-by-step explanation:

y = 3x + 2

y = 3x - 6

Since both equations are equal to y, you can set them equal to each other.

3x + 2 = 3x - 6

subtract 3x from both sides

2 = -6

This equation is not true, therefore your answer is no solutions.

Step-by-step explanation:

∠A and \angle B∠B are complementary angles. If m\angle A=(8x+27)^{\circ}∠A=(8x+27)

and m\angle B=(6x-21)^{\circ}∠B=(6x−21)

, then find the measure of \angle B∠B.

Answers

Answer:

∠ B = 15°

Step-by-step explanation:

Complementary angles sum to 90° , that is

∠ A + ∠ B = 90 , substitute values

8x + 27 + 6x - 21 = 90

14x + 6 = 90 ( subtract 6 from both sides )

14x = 84 ( divide both sides by 14 )

x = 6

Thus

∠ B = 6x - 21 = 6(6) - 21 = 36 - 21 = 15°

What are the coordinates of B and how is that the answer ?

Answers

Step-by-step explanation:

Point A = (-1, -3).

Midway of AB = (-3, 2).

Let Point B = (x, y).

Then (-1, -3) - (-3, 2) = (-3, 2) - (x, y).

=> (2, -5) = (-3-x, 2-y).

We have -3 - x = 2 and 2 - y = -5.

So x = -5 and y = 7.

Hence, point B = (-5, 7).
