Answer:

The answer is f(x)=2

Step-by-step explanation:

When the input is given it means that the x is substituted by that number.

so 3x3-7.

3x3-7

9-7=2.

The f of x is equivalent to 2.

I hope this helps :D

i think i hope its right

Step-by-step explanation:

The total of windows they have cleaned = 12

They have cleaned 12 windows = they earn £ 36.

If they have cleaned 1 window = they earn 36/12 = £3.

So Tom have cleaned 7 windows = Tom earn = 3 * 7 = £21.

The graph will look like this

9 children and 0 adults, 6 children and 2 adults, 3 children and 4 adults, or 6 adults and 0 children went to the park.

Given that a group wants to visit a water park over the summer, and tickets cost $ 10 for each child and $ 15 for each adult, and the group has a total of $ 90 to spend on tickets to the water park, to determine how many people from each group went to the park, the following calculation should be made:

10X + 15Y = 90

Thus, there are different correct options:

9 children and 0 adults, 6 children and 2 adults, 3 children and 4 adults, or 6 adults and 0 children went to the park.

Answer:

The slope (m) = 2/3

Step-by-step explanation:

Taking any two points on the line:

(0,-2) & (3,0)

Using the slope formula to calculate the slope (m):

m = [tex]\frac{y2-y1}{x2-x1}[/tex]

= (0-(-2))/(3-0)

= (0+2)/3

= 2/3

Hence, the slope (m) is 2/3.

Hope this helps and be sure to have a wonderful time ahead at Brainly! :D

Answer:

I am pretty sure thats acute triangle but not 100%

Step 1: Find the slope

Slope Formula = (y2 - y1) / (x2 - x1)

Point 1 = (-2, 4)

Point 2 = (-3, 5)

slope = (5 - 4) / (-3 - - 2) = (5 - 4) / (-3 + 2) = (1) / (-1) = -1

Step 2: Find the y-intercept

To find the y-intercept, we will take one of the given points as well as the slope and plug them into slope-intercept form. Then, we will solve for b.

Slope-Intercept Form: y = mx + b

Point = (-2, 4)

Slope = -1

4 = -1(2) + b

4 = -2 + b

b = 6

Step 3: Put it all together

Now that we have the slope and the y-intercept, all that's left to do is plug it into slope-intercept form.

Slope-Intercept Form: y = mx + b

Slope = -1

Y-Intercept = 6

y = -x + 6

Hope this helps!! :)

The "million" part is already taken care of by your teacher.  

====================================================

Explanation:

x = profit last year (millions of dollars)

x+2.54 = profit this year, which is 2.54 million more than last year

x+2.54 = 1.38

x = 1.38-2.54

x = -1.16

The profit last year was -1.16 million dollars

This is the same as writing -1,160,000 dollars of profit.

A negative profit indicates that the company lost money. This is when the company is spending more than what they earn (i.e. they are in some kind of debt).

Answer:

31.75$

Step-by-step explanation:

To add sales tax, you multiply the amount you start with by 1 + what the tax is.

In this case, you multiply 29,95 by 1.06%.

29.95 × 1.06% = 31.747 or 31.75$

Answer:

30.01

Step-by-step explanation:

29.95+6%= 30.01

=3√(4)(4)(4)

=4

Answer:

No Solution

Step-by-step explanation:

2 (n - 8) < 16 + 2n

Step 1.) Multiply 2 by n and -8

2n - 16 < 16 + 2n

Step 2.) Add the 16 on the left to the 16 on the right

2n < 32 +2n

Step 3.) Subtract 2n on the right from the 2n on the left

0 < 32

If the answers on both sides had both been 0 then it would have been Infinite Solutions but because there is only one 0, the answer is No Solution

Answer:

The Greatest Common Factor of  

15

and

25

is  

5

.

The factors of  

15

are  

3

and

5

(the number itself and 1 do not count).

The factor(s) of  

25

is  

5

. After all, it is a square number.

The only factor that is in common is  

5

(again remember that 1 does not count here -although  

1

is common,  

5

is higher)

Hope I helped!

Step-by-step explanation:

Point-slope form is: y - y1 = m ( x - x1 )

You plug in your slope for m and the x and y values from that point for x1 and y1.

    y - (-8) = -3/4 ( x - (-3) )

Be sure to clean up the "minus a negative" to get

    y + 8 = -3/4 ( x + 3 )

For part A, x equals 0.

Therefore (7²)⁰=7⁰=1

For part B, x could be any number because 0 multiplied by any number equals 0. eg. (7⁰)⁹=7⁰=1

Hope this helps!

Answer:

x = 11°

Step-by-step explanation:

3x + 19 + 2x + 8 = 7x + 5

5x + 27 = 7x + 5

27-5 = 2x

22/2 = x

11 = x

Answer: if you meant: 125, 729, 225, 512.

The answer is 225

Step-by-step explanation:

[tex]\sqrt[3]{125}[/tex] = 5

[tex]\sqrt[3]{729}[/tex] = 9

[tex]\sqrt[3]{512}[/tex] = 8

[tex]\sqrt[3]{225}[/tex] = 6.08220199557

Answer:

Line 1 and 2 are neither

Line 1 and 3 are parallel

Line 2 and 3 are neither

Step-by-step explanation:

y = ⅗x -6

10x-6y=6

5y=3x+6

-6y= -10x + 6

y= -10/-6x +6

y= 5/3x+6

5y= 3x+6

y=⅗x+6
