Answer: See explanation

Step-by-step explanation:

You didn't give further information that will be useful in solving the question but let me help out.

Let's say the price of a car is $30,000 and the sales tax is 4%, the tax that will be added to the car would be:

= 4% × $30,000

= 4/100 × $30,000

= 0.04 × $30,000

= $1200

Answer:

You will earn $323.4 per week

Step-by-step explanation:

We are given:

Cost per hour = $13.20

Number of hours you work each week = 24.5 hours

We need to find how much money do you earn per week.

Amount of money you earned per week = Cost per hour * Number of hours worked

Amount of money you earned per week = 13.20 * 24.5

Amount of money you earned per week = 323.4

So, you will earn $323.4 per week

Answer:

y - 3 = - 5(x + 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 5 and (a, b) = (- 1, 3 ), then

y - 3 = - 5(x - (- 1) ) , that is

y - 3 = - 5(x + 1)

Answer:

Step-by-step explanation:

point slope formula is:   y-y1 = m(x-x1)  ( memorize this formula there is also slope intercept)

now plug in your point and slope where m = slope and the number of the given point are (x1,y1)

y-3 = -5(x-(-1))

y-3 = -5(x+1)

Answer:

a) 3<x<8

b) -4<x<-2

c) -6<x<5

d) -21/4 < x-8/3

e) 0<x<7

Step-by-step explanation:

Given the following inequalities

a)  x > 3, 2x - 3 < 15

Solve 2x - 3 < 15

2x < 15+3

2x<18

x<18/2

x<8

Combine x>3 and x<8

If x>3, then 3<x

On combining, we have:

3<x<8

b) For the inequalities 25 > 1 - 6x, 1 > 3x + 7

25 > 1 - 6x

25-1>-6x

24>-6x

Divide through by -6:

24/-6 > -6x/-6

-4 <x

For the inequality 1 > 3x + 7

1-7>3x

-6>3x

-6/3 > 3x/3

-2 > x

x < -2

Combining both results i.e -4 <x and x < -2, we will have:

-4<x<-2

c) For the inequalities 2x - 7<3< 27 + 4x

On splitting:

2x - 7<3 and 3< 27 + 4x

2x < 3+7

2x<10

x<5

Also for 3< 27 + 4x

3-27<4x

-24<4x

-24/4 < 4x/4

-6<x

Combining both solutions i.e x<5 and -6<x will give;

-6<x<5

d) For the inequalities 3x + 8 <0 < 21 + 4x

3x + 8 <0

3x < -8

x < -8/3

Also for 0 < 21 + 4x

0-21<4x

-21<4x

-21/4 < 4x/4

-21/4 < x

Combining -21/4 < x and x < -8/3 will give;

-21/4 < x-8/3

e) For the inequalities 5x - 36 < -1 < 2x – 1​

Split:

5x - 36 < -1

5x < -1+36

5x<35

5x/5 < 35/5

x < 7

For the expression -1 < 2x – 1​

-1+1 < 2x

0 < 2x

0<x

Combining both inequalities 0<x and x < 7 will give:

0<x<7

Answer:

  yes, SAS

Step-by-step explanation:

Two sides are given, either side of a vertical angle. So, the angles are the same. If the sides are proportional, the similarity will be by SAS (two sides, either side of an angle).

The ratios of short to long sides are ...

  39/52 = (3·13)/(4·13) = 3/4

  63/84 = (3·21)/(4·21) = 3/4

The sides are proportional and the angle between them is congruent, so ...

  the triangles are similar by SAS.

Answer:  20 songs is the initial value.

Step-by-step explanation: The graph shows that at the beginning of January was 20. She adds 5 songs per month.

The equation would be y = 5x + 20  where y is her total number of songs and x is the number of months that have passed.

Step-by-step explanation:

Answer:

[(a - 2b)(a + 2b) + 9)][(a - 2b)(a + 2b) - 9]

This can be written as the difference of 2 squares:

(a^4 - 8a^2b^2 + 16b^4) -81

= (a^2 - 4b^2)^2 - 81

=[(a^2 - 4b^2) + 9] [(a^2 - 4b^2) - 9]

= [(a - 2b)(a + 2b) + 9)][(a - 2b)(a + 2b) - 9]

The factorized form of the given expression will be as:

[(a - 2b)(a + 2b) + 9)][(a - 2b)(a + 2b) - 9]

Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).

The expression is given in the question as:

(a⁴ - 8a²b² + 16b⁴) - 81

We have to determine the factorized form of the given expression

As per the given question, the required solution would be as:

(a⁴ - 8a²b² + 16b⁴) - 81

This can be written as the difference between 2 squares:

⇒ (a² - 4b²)² - 81

⇒ [(a - 4b²) + 9] [(a² - 4b²) - 9]

⇒ [(a - 2b)(a + 2b) + 9)][(a - 2b)(a + 2b) - 9]

Answer:

Step-by-step explanation:

for a triangle inscribed in a semicircle that angle is always 90 degrees

9514 1404 393

Answer:

  C.  90°

Step-by-step explanation:

A triangle inscribed in a semicircle is always a right triangle. The measure of angle Y, which subtends an arc of 180°, is half the measure of the arc it subtends, so is 180°/2 = 90°.

Answer:

(3)

Step-by-step explanation:

the sum of n and 5 is (n + 5), then multiply by 3 gives

3(n + 5)

The result is at least 17 which means it must be greater than or equal to 17

Answer:

[tex]5x = 15 - 10 \\ 5x = 5 \div 5 \\ 5x = 1[/tex]

Answer:

6x +35 +9x = 15(x+4)

6x +35 +9x = 15x + 60

15x +35 =15x +60

0x= 25

0x= no solution

Step-by-step explanation:

The equation has no solution.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

For example, 3x – 5 = 16 is an equation.

Given is an equation, 6x +35 +9x = 15(x+4), we need to find the solution,

6x +35 +9x = 15(x+4)

6x +35 +9x = 15x + 60

15x +35 =15x +60

0 = 25

Since, 0 ≠ 25, this is a contradiction.

Therefore, the equation has no solution.
