Which expression is equivalent to 17x − 8x + 2 and why?

A. 2 − 9x, because (17x − 8x) + 2 = −9x + 2 = 2 − 9x
B. 2 + 9x, because (17x − 8x) + 2 = 9x + 2 = 2 + 9x
C. 11x, because 17x − 8x + 2 = 9x + 2 = 11x
D. 7x, because 17x − 8x + 2 = 17x − 10x = 7x

Answer:

The percentage decrease = 25%

Step-by-step explanation:

Given

To determine

Using the percentage decrease formula

% decrease = [Starting Value - Final Value] / [Starting Value] × 100

                    = [800 - 600] / [800] × 100

                    = [200] /  [800] × 100

                    = 0.25 × 100

                    = 25%

Therefore, the percentage decrease = 25%

Answer:

x= -1.8

Step-by-step explanation:

4x-22=9x+2(1-4x)

2(1 - 4x)

so you have to distribute

new equation

4x-22=9x+2-8x

you combine like terms on the right

9x + 2 -8

+8. +8

17x+2

new equation

4x-22=17x+2

-4x. -4x

-22=13x + 2

-2. -2

-24=13x

-24÷13= - 1.8

X= -1.8

Answer:

[tex]4x - 22 = 9x + 2 - 4x \\ - x = 24 \\ x = - 24[/tex]

Answer:  y = (6/5)x-8

Slope = 6/5 = 1.2

Y intercept = -8

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

Work Shown:

m = 6/5 = 1.2 is the given slope

(x,y) = (5,-2) is the point the line goes through

y = mx+b .... slope intercept form

y = 1.2x + b .... plug in the given slope

-2 = 1.2*5 + b ... plug in the coordinates of the given point

-2 = 6 + b

-2-6 = 6+b-6 .... subtracting 6 from both sides

-8 = b

b = -8

The equation y = mx+b turns into y = 1.2x-8

This is equivalent to y = (6/5)x-8

Answer:

domain: (-∞,∞)

range: (-∞,∞)

Step-by-step explanation:

You need to convert this into a linear equation (y=mx+b)

So we add 2y and divide by 2 to get y by itself

that gives us 5x-2=y

If you pictures this graph in your head you'll see that the domain and range are all real numbers

Answer:

42.11

Step-by-step explanation:

Add all of the numbers, and then divide the total of the numbers by 9. With 9 being how many numbers are added.

The mean of the given data set is approximately 42.11.

To find the mean of a set of data, you need to sum up all the values and then divide the sum by the total number of values.

Given the data: 63, 40, 51, 70, 36, 21, 51, 28, 19

Here, there are 9 values.

Add up all the values:

63 + 40 + 51 + 70 + 36 + 21 + 51 + 28 + 19 = 379

Divide the sum by the total number of values:

379 / 9 = 42.11

Therefore, the mean of the given data set is approximately 42.11.

Step-by-step explanation:

Answer:

6 work out sessions

Step-by-step explanation:

From the above question, we know that:

Jasmine has a goal to workout a total of at least 6 hours this week.

Her workout sessions are always 3/4 an hour long.

Hence: Her total workout sessions

3/4 hour = 1 workout session

6 hours = x

Cross Multiply

3/4 × x = 6 × 1

x = 6/3/4

x = 6 ÷ 3/4

x = 6 × 4/3

x = 8 work out sessions

We are told that:

She already worked out for 1 1/2 hours.

Hence: if :

3/4 hour = 1 workout session

1 1/2 hours = x

Cross Multiply

3/4 × x = 1 1/2

x = 1 1/2 ÷ 3/4

x = 3/2 ÷ 3/4

x = 3/2 × 4/3

x = 2 work out sessions

Therefore:

the minimum number of workout sessions she would need to complete in order to achieve her weekly goal is calculated as:

8 work out sessions - 2 work out sessions

= 6 work out sessions

Converting this to workout sessions

Answer:

75 minutes or 1 hour and 15 minutes.

Step-by-step explanation:

First, we need to figure out what 1/4 of an hour is. If an hour is 60 minutes, 60/4 is 15. So we know it will take 15 minutes to complete 1/5 of the worksheet. All we have to do now is multiply 15 by 5 and get 75 OR 1 hour and 15 minutes.

Answer: 14k-8

Step-by-step explanation:

I've attached an image showing the intersection and the angle.

Answer:

C: They are complementary

Step-by-step explanation:

We can see from the image that angle 1, angle 2 and 90° are on a straight line. We know that sum of angles on a straight line is 180°. Thus;

∠1 + ∠2 + 90° = 180°

Rearranging, we have;

∠1 + ∠2 = 180° - 90°

Thus;

∠1 + ∠2 = 90°

Now, from angle proofs in trigonometry, it states that If the non-common sides of two adjacent angles add up to 90°, then it means that the angles are complementary.

In our problem here, sum of ∠1 and ∠2 equals 90°. Also, they are the non-common sides of 2 adjacent angles. Thus, we can say that they are complementary.

Answer:

3 1/6 cups of flour.

Step-by-step explanation

Answer: 3 1/6 cups

Step-by-step explanation:

The question is asking to find the sum of both types of flour. 1 1/2 cups of the first flour was used and 1 2/3 cups of the second was used. In order to combine these fractions, they must first have a common denominator. the fractions can be made into 1 3/6 and 1 4/6 in order to do this. Next, add the fractions to get 2 7/6 cups of flour. Finally, simplify the previous fraction to get the final answer of 3 1/6 cups.

Answer:

Step-by-step explanation:

The parent function of g(x) = 2*3^x-4 would be 3^x

The transformation would include: shifting parent function 4 units down (-4) and compressing the function (2)

The movement (shifting) of the graph is caused by the y-intercept. If the y-intercept is positive, the graph moves up and vice versa.

The coefficient which is multiplied determines whether the function is compressed (squeezed) or stretched. If the coefficient is less than 1, then the function is stretched. If the coefficient is greater than 1, then the function is compressed.

Answer:

60

Step-by-step explanation:

The two angles that are shown are corresponding meaning that they are the same angles so to solve for x you would set up an equation and because they are the same the equation would be

10x-20=7x+4

step 1 add 20 to each side

10x=7x+24

step 2 subtract 7 from each side

3x=24

step 3 divide  by 3 to each side

Answer:

a₇₆ = - 134

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 16 and d = a₂ - a₁ = 14 - 16 = - 2, then

a₇₆ = 16 + (75 × - 2) = 16 - 150 = - 134
