What is the value of x in the equation
4z +16
12
= х - 4?

The amount charged is an illustration of a linear equation.

Tina charges $39 for 4 hours

The given parameters are:

[tex]Base = 15[/tex] --- amount charged for the first hour

[tex]Rate = 8[/tex] --- amount charged for the extra hours

If Tina babysits for 4 hours, it means that:

So, the total charges is:

[tex]Total = 15 + 3 \times 8[/tex]

[tex]Total = 15 + 24[/tex]

[tex]Total = 39[/tex]

The ordered pair is (4,39)

It means that:

She charges $39 for 4 hours

Answer:

→ 9x^2 - 4x - 3 = [41].

Step-by-step explanation:

Simplify:

9x^2 - 4x -3

=> 9(-2)^2 - 4(-2) - 3 [∵ x = 1 (Given)]

=> 9(4) - 4(-2) - 3

=> 36 + 8 - 3

=> 44 - 3

=> 41 Ans.

Answer:

The value of the algebraic expression when n is given as 6 will be 38.

An algebraic expression is when we use numbers and words in solving a particular mathematical question.

Based on the information given in the question, the expression will be:

= 1 + 7n - 5

Note that the value of n = 6

Therefore, 1 + 7n - 5 will be:

= 1 + 7n - 5

= 1 + 7(6) - 5

= 1 + 42 - 5

= 38

Step-by-step explanation:Therefore, the value of the algebraic expression when n is given as 6 is 38.

You weren't clear with your question, but I am assuming you want to solve for the variable "x."

-2(x - 6) + 7 = 35

-2x + 12 + 7 = 35; distribute the -2

-2x + 19 = 35

-2x = 16; isolate the x variable (the variable you want to solve)

x = -8; divide by -2 to isolate the x variable

Answer:

[tex]x=-8[/tex]

Step-by-step explanation:

1) Distribute

[tex]-2(x-6)+7=35\\-2x+12+7=35[/tex]

2) Add the numbers

[tex]-2x+12+7=35\\-2x+19=35[/tex]

3) Subtract 19 from both sides of the equation

[tex]-2x+19=35\\-2x+19-19=35-19[/tex]

4) Simplify

A. Subtract the numbers

[tex]-2x+19-19=35-19\\-2x=35-19[/tex]

B. Subtract the numbers

[tex]-2x=35-19\\-2x=16[/tex]

5) Divide both sides of the equation by the same term

[tex]-2x=16 \\\frac{-2x}{-2} =\frac{16}{-2}[/tex]

6) Simplify

A. Cancel terms that are in both the numerator and denominator

[tex]\frac{-2x}{-2} =\frac{16}{-2}[/tex]

B. Divide the numbers

[tex]x=-8[/tex]

Answer:

See Below

Step-by-step explanation:

Making $250/week in salary and 10% of the $975 in sales.

First find what 10% of $975 equals.  The decimal equivalent of 10% is 0.10

So multiply the decimal and total sales.

0.10 x 975 = 97.5

Her weekly salary plus the commission would be:

$250 + $97.50 = 347.50

If you don't know her sales for the week, you can use X to represent the sales.  The equation would be:

0.10x   +   250  =  y       where y is her total pay.

Answer:

2 x 7 x 3²

Step-by-step explanation:

When finding primes, you use the method I attatched as a picture. Start with the large number at the top, slowly dividing it by factors of it.

The picture shows that the primes 126 is a product of is:

2, 7, 3, 3

Or:

2 x 7 x 3 x 3

This can be simplified into:

2 x 7 x 3²

Answer:

a^(4/15)

Step-by-step explanation:

rules of indices:

WHEN MULTIPLYING POWERS WITH THE SAME BASE YOU ADD THE POWERS

a^(1/5) × a^(2/3) = a^(1/5 + 2/3)

a^(13/15)

WHEN DIVIDING POWERS WITH THE SAME BASE YOU SUBTRACT THE POWERS

a^(13/15) / a^(3/5) = a^(13/15 - 3/5)

a^(4/15)

NOTE: YOU HAVE TO FOLLOW BODMAS RULE IN THE QUESTION.. AND PLEASE LOOK OUT FOR THE POWERS WITH THE SAME BASE. IF BASE IS DIFFERENT YOU CANNOT SIMPLIFY...

Answer:

True

Step-by-step explanation:

The Factor theorem states that  for any polynomial f(x) if f(c)=0 then x-c is a factor of the polynomial f(x).

If any polynomial f(x) is divided by x-a and remainder is 0 that means f(a)= 0 .In other words we can say x-a is a factor of the polynomial f(x).So the statement :If a polynomial is divided by (x-a) and the remainder equals zero then (x -a) is a factor of the polynomial is True.
