input 19
function x-5
what output

Answer: x = 0

Step-by-step explanation: x+5=−5x+5

Add 5x to both sides.

x+5+5x=5

Combine x and 5x to get 6x.

6x+5=5

Subtract 5 from both sides.

6x=5−5

Subtract 5 from 5 to get 0.

6x=0

Product of two numbers is equal to 0 if at least one of them is 0. Since 6 is not equal to 0, x must be equal to 0.

x=0

Answer:

1 kg of mushrooms costs £2.7.

Step-by-step explanation:

Step 1: Write equations.

Let a be the cost of apples per kg and m the cost of mushrooms per kg.

First equation: Ibrar buys 3 kg of apples. He also buys 0.4 kg of mushrooms. The total cost is £6.93.

[tex]3a + 0.4m = 6.93[/tex]

Second equation: 1 kg of apples cost £1.95.

[tex]a = 1.95[/tex]

Step 2: Solve the system of equations.

1) [tex]3a + 0.4m = 6.93[/tex]

2) [tex]a = 1.95[/tex]

Substitute a in the first equation with a from second.

[tex]3a + 0.4m = 6.93\\3(1.95) + 0.4m = 6.93[/tex]

Solve for m.

[tex]5.85 + 0.4m = 6.93\\0.4m = 6.93 - 5.85 \\0.4m = 1.08\\m = \frac{1.08}{0.4}\\m = \text{\£}2.7[/tex]

The cost of 1 kg of mushrooms is £2.7.

Two or more expressions with an Equal sign is called as Equation.

Given that Ibrar buys 3kg of apples

Ibrar buys 0.4kg of mushrooms.

The total cost is £6.93

3x+0.4y=6.93...(*)

1kg of apples cost is £1.95

x=1.95

Substitute the value of x in *

3(1.95)+0.4y=6.93

5.85+0.4y=6.93

Subtract 5.85 on both sides

0.4y=6.93-5.85

0.4y=1.08

Divide both sides by 0.4

y=2.7

Hence, the cost of 1 kg of mushrooms is £2.7.

The average speed of Keane’s journey in mph is 56.25 mph (miles per hour)

From the question, we are to determine Keane's average speed

Average speed is given by the formula,

Average speed = Distance / Time

Distance travelled = 180 miles

Now, we will calculate the time spent

From the given information,

He leaves his home at 09:30 and arrives in Liverpool at 12:42

09:30 to 12:42 is 3 hours 12 minutes

∴ Time = 3 hours 12 minutes = 3 + (12/60) hours = 3.2 hours

Thus,

Average speed = 180 / 3.2

Average speed =  56.25 mph (miles per hour)

Hence, the average speed of Keane’s journey in mph is 56.25 mph (miles per hour)

Answer:

2sin((1)x + 135)-3

Step-by-step explanation:

Asin(Bx+C)+D

A = amplitude = distance from top to bottom divided by 2

y value of top = -1

y value of bottom = -5

distance from top to bottom = -1 - (-5) = 4

divide by 2 to get 4/2 = 2 as our amplitude

2π/B = period

in this case, we're working in degrees for our x axis - 2π = 360°

thus, 360°/B = period

period = time it takes to get from one high to the next (alternatively, one low to the next etc.) = 360 degrees in this case

thus, 360°/B = 360°

divide both sides by 360° and multiply both sides by B to isolate B

360/360 = B = 1

phase shift = -C/B

phase shift refers to how much the graph is shifted to the left/right. normally, the middle of a sin wave is at 0, with a peak being to the right of it. now, the middle of the sin wave (which has a peak to the right of it) is at x = -135 degrees to the right of a regular sine wave

thus,

-135 degrees = -C/B

B = 1

-135 degrees = -C

C = 135 degrees

D = vertical shift

the center is now at y = -3. normally, the center is at y = 0. thus, D = -3

our formula is thus

2sin((1)x + 135)-3

Exact Form: y = − 1/10

Decimal Form: y = − 0.1

Multiply both sides of the equation by 100.

To find the opposite of 5y−17, find the opposite of each term.

The opposite of −17 is 17.

Combine 155y and −5y to get 150y.

Subtract 17 from both sides.

Subtract 17 from 2 to get −15.

Divide both sides by 150.

Using proportions, it is found that the family will drive 482.8 km on the new route.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, the family travels a distance of 125% of 240 miles, hence the distance is:

D = 1.25 x 240 = 300 miles.

Since there are are approximately 48.28 kilometers in 30 miles, and 300/30 = 10, the distance in kilometers is given by:

D = 48.28 x 10 = 482.8 km.

An equation is formed of two equal expressions. The cost of a new book is $7.43, while the cost of an old book is $8.86.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the cost of 14 used books is $124. Therefore, the cost of a single used book is,

Cost of single used book(u) = 124/14 = $8.86

Also, the cost of 12 used books and 4 new books is $136. Therefore, the equation can be written as,

12u + 4n = 136

12(8.85) + 4n = 136

106.2 + 4n = 136

n = $7.43

Hence, the cost of a new book is $7.43, while the cost of an old book is $8.86.

Answer:

the 4th option because 24 months times the amount plus the 39.99 to set up would get you a final answer

Answer:

39.99/24c = 351.75

24c + 39.99 = 351.75

Where c is the cost to set up an account

Step-by-step explanation:

Knowing that it given:

What is the cost(c) month for using the service for 24 months?

That means "Cost = c"

That leads us to the answer:

"Where c is the cost to set up an account"

We also know that we are finding for the 24 months thus 24c.

That leads us to

24c + 39.99 = 351.75 and 39.99/24c = 351.75

Hence, the answers are:

39.99/24c = 351.75

24c + 39.99 = 351.75

Where c is the cost to set up an account
