Given: -7(x+2)+4x=6(2x-4); Prove x=2/3

Answers

Answer:

see below

Step-by-step explanation:

-7(x+2)+4x=6(2x-4)

Distribute

-7x -14 +4x = 12x -24

Combine like terms

-3x-14 = 12x-24

Add 3x to each side

-3x-14+3x = 12x-24+3x

-14 = 15x-24

Add 24 to each side

-14+24 = 15x -24+24

10 = 15x

Divide each side by 15

10/15 =15x/15

2/3 =x

What is 7x-6=9x+6? PLEASE HELP ME!!!!!!!!!!!!!

Answers

Answer:

x=-6

Step-by-step explanation:

7x-9x=6+6

-2x=12

x=-6

Answer:

x = -6

Step-by-step explanation:

Step 1: Write out equation

7x - 6 = 9x + 6

Step 2: Subtract 7x on both sides

-6 = 2x + 6

Step 3: Subtract 6 on both sides

-12 = 2x

Step 4: Divide both sides by 2

-6 = x

Step 5: Rewrite

x = -6

Answers

Answer:

f(- 2) = 21

Step-by-step explanation:

To evaluate f(- 2) substitute x = - 2 into f(x)

f(- 2) = - 5(2(- 2) + 1) + 6 = - 5(- 4 + 1) + 6 = - 5(- 3) + 6 = 15 + 6 = 21

What is the equation of the line that passes through the point (2,-6)and has a slope of −1?

Answers

Step-by-step explanation:

Hey there!!

Just simply work with it.

We know that we have to use one point formula to find the equation of a st.line passing through point and slope is given.

So, just do accordingly.

The point is (2,-6) and slope is -1.

[tex](y - y1) = m(x - x1)[/tex]

Where, "m" is a slope.

Put all values.

[tex](y + 6) = - 1(x - 2)[/tex]

Simplify them to get answer.

[tex](y + 6) = - x + 2[/tex]

[tex]y = - x - 4[/tex]

Therefore the equation is y= -x-4 OR can be written as x+y+4=0.

Step-by-step explanation:

-9

0

9

18

Answer:

see explanation

Step-by-step explanation:

Evaluate u for each value of n by substituting value of n into u, that is

n = - 1 → u = - 5(- 1)² + 4(- 1) = - 5(1) - 4 = - 5 - 4 = - 9

n = 0 → u = - 5(0)² + 4(0) = 0 + 0 = 0

n = 1 → u = - 5(1)² + 4(1) = - 5 + 4 = - 1

n = 2 → u = - 5(2)² + 4(2) = - 5(4) + 8 = - 20 + 8 = - 12

Thus

   n          u

   - 1         - 9

      1          - 1

      2          - 12

Which of the Following is the solution to 4|x+3| greater than equal to 8? Options are as followed: A.x less then equal to -5 or x greater than equal to -1 B. x greater than equal to -1 C.x less then equal to -5 and x greater than equal to -1 D. x greater then equal to -5 and x greater then equal to -1

Answers

Answer:

A

Step-by-step explanation:

4|x+3| >= 8

Divide both sides by 4

4|x+3| / 4 >= 8/4

|x+3| >= 2

Rewritten as

-2 >= x + 3 >= 2

Subtract 3 from all sides

-2 - 3 >= x + 3 - 3 >= 2 - 3

-5 >= x >= -1

Or

-1 <= x <= -5

x less then equal to -5 or x greater than equal to -1

Men = 40, Women = 30

Ratio of women to men

[tex] = \frac{30}{40} = \frac{3}{4} = 3 : 4 \\ [/tex]

The Ratio of the women to men is 3/4.

What is ratio?

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given, In a small business, 40 of the employees are men and 30 of the employees are women.

Since There are 30 women on 40 men in the company

Thus, ratio of the women to men = 30/40

The ratio of the women to men = 3/4

Therefore, the ratio of women to men is 3/4 in the organization.

Which of the following equations is equivalent to 3x + 4y = 15?

Answers

Letter A is the answer because
4y = 15 - 3x
so y = 15/4 -3x/4

The equivalent expression of 3x + 4y = 15 is y = 15/4 - 3x/4 so option (A) will be correct.

What is the equation?

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

In another word, the equation must be constrained with some constraints.

Given the expression,

3x + 4y = 15

4y = 15 -3x

y = 15/4 - 3x/4

Hence "The equivalent expression of 3x + 4y = 15 is y = 15/4 - 3x/4".

Find NQ if NP = 13 cm and line l is a segment bisector.

Answers

Answer:

NQ = 26 cm

Step-by-step explanation:

A line bisector divides a line into two equal segments.

Given that line l is the bisector of segment NQ, it then means it divides NQ into two equal segments, namely, segment NP and segment PQ.

Thus, NP = ½ of segment NQ

Therefore, if NP = 13 cm,

13 = ½*NQ

multiply both sides by 2

2*13 = NQ

26 = NQ

NQ = 26 cm

In the given figure, C is the midpoint of AB and M is the midpoint of AC . Find the length of NB if MC = 4 and AN = 14.

Answers

Answer:

Given MC = 4

AN = 14

To Find, the length of NB

Step-by-step explanation:

AB is a line which has midpoint “C”. Now the line is divided into two equal portion AC and CB.

The AC has midpoint “M” and MC is 4, so AM will also be 4.

N is the midpoint of CB. So, CB = CN + NB

Now we know AC = AM + MC = 4  + 4 =8

Given, AN = 14

AN = AC + CN

14 = 8 + CN

CN = 6

Since N is the midpoint of CB then, CN = NB

Therefore, the NB is 6

Some rational numbers are whole numbers. True or False

Answers

Answer:

False

Step-by-step explanation: A rational number is any number can be expressed as a fraction. Whereas, a whole number is a positive number without a decimal or fractions. Every rational number is may or may not be a whole number.

The statement "Some rational numbers are whole numbers" is:

True

Some rational numbers are whole numbers. True or False?

A rational number is any number that can be expressed as a fraction of two integers, where the denominator is not zero. A whole number is any integer that is not negative.

All whole numbers are rational numbers. This is because any whole number can be expressed as a fraction with a denominator of 1.

For example, the whole number 3 can be expressed as the rational number 3/1.

However, not all rational numbers are whole numbers. For example, the rational number 1/2 is not a whole number, because it cannot be expressed as a fraction with a denominator of 1.

Therefore, "Some rational numbers are whole numbers" is True.
