Answer:

[tex]\frac{13}{32}[/tex]

Step-by-step explanation:

The multiplier that would be used to calculate the depreciation of the car is 0.83^y.

Depreciation is when the value of an asset declines due to wear and tear.

The equation that can be used to represent depreciation is:

Value of the asset x (1 - rate of depreciation)^years

$31,000 x 0.83^y.

Answer:

x = 11/7 y = -1/7

Step-by-step explanation:

2x + y = 3

2x + y - 2y = 3 - 2y

y = 3 - 2x

x - 3(3 - 2x) = 2

x - 9 + 6x = 2

x - 9 + 6x + 9 = 2 + 9

x + 6x = 11

7x = 11

7x / 7 = 11/7

x = 11/7

2(11/7) + y = 3

22/7 + y = 3

22/7 + y - 22/7 = 3 - 22/7

y = -1/7

Answer:

(¹¹⁄₇, -⅐)

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}2x+y=3&\\x-3y=2\end{cases}[/tex]

What is the elimination method?

The elimination method is when you rewrite the two equations so that when added together, one of the two variables (x or y) is eliminated.

Step 1: Multiply the first equation by [tex]3[/tex].

[tex]\implies (3)2x+(3)y=(3)3[/tex]

[tex]\implies 6x+3y=9[/tex]

Step 2: Add the above equation to the second equation to eliminate 3y.

[tex]\begin{array}{r l}6x+3y & = 9\\+\ x-3y&=2\\\cline{1-2}7x&=11 \end{array}[/tex]

Step 3: Solve for x (by dividing both sides by 7).

[tex]\implies \dfrac{7x}{7}=\dfrac{11}{7}[/tex]

[tex]\implies \boxed{x=\dfrac{11}{7}}[/tex]

Step 4: Substitute ¹¹⁄₇ as the value of [tex]x[/tex] in any of the given equations and solve for [tex]y[/tex].

[tex]\implies 2\left(\dfrac{11}{7}\right)+y=3[/tex]

[tex]\implies \dfrac{22}{7}+y=3[/tex]

Step 5: Convert [tex]3[/tex] into a fraction and subtract ²²⁄₇ from both sides of the equation.

[tex]\implies \dfrac{22}{7}-\dfrac{22}{7}+y=\dfrac{21}{7}-\dfrac{22}{7}[/tex]

[tex]\implies \boxed{y=-\dfrac{1}{7}}[/tex]

The solution to the given system of equations is (¹¹⁄₇, -⅐).

Step-by-step explanation:

9.

the first we see when going from left to right : the line goes down, so it has a negative slope (factor of x).

then we look at the y-intercept (the point where the line crosses the y-axis) : negative y and around -5.

with all that we have eliminated B and D.

and not only does the line go down, it goes sharply down. so, the absolute value of the slope must be bigger.

therefore, C is the right answer.

and a quick check confirms, as the slope -10/3 means that for a change of x by +3 units causes y to change by -10, and that is what we are seeing on the chart.

at x = -3 it looks like y is about +5.

and at x = 0 (change by +3) it looks like y is about -5 (change by -10).

10.

the y-intercept does not give us a clue here, it is 1 for all 4 options, and the graph confirms it.

but this line goes up, so the slope is positive.

it is rather "flat" and by far not even diagonally, so the absolute value of the slope must be a small value (much smaller than 1, as a slope of 1 means "diagonally").

therefore, D is the right answer.

a quick check confirms, as the slope 1/5 means that for a change in x by +5 would lead to a change in y by +1.

and that is what we are seeking on the chart.

at x = -5 it looks like y is about 0.

at x = 0 (change by +5) it looks like y is about +1 (change by +1) - the y-intercept.

Answer:

$9 per hour

Step-by-step explanation:

   Total number of hours = hours each night x number of nights

⇒ Total number of hours = 2 x 10 = 20 hours

   Hourly rate = total earned ÷ total number of hours

⇒ Hourly rate= 180 ÷ 20 = 9

Therefore, hourly rate = $9 per hour

Answer:

9 dollars per hour

Step-by-step explanation:

First determine the total number of hours

2 hours * 10 nights = 20 total hours

Divide the total amount paid by the total hours to get the rate

180 /20 = 9

She is paid 9 dollars per hour

Step-by-step explanation:

Answer:

302.333... Its a repeating number.

Step-by-step explanation:

Answer:

The first part is correct! → There are 4 distinct instruments to distribute to 4 distinct people. And there are 4!=24 distinct ways of doing this.

For the second part. → Jay and Jack can only play 2 instruments, therefore we have 2 instruments for 2 people, and the distribution for these guys can be made in 2!=2 distinct ways.

Then, note that all that is left are 2 distinct instruments for 2 people. So there is an additional 2 distinct ways of doing this distribution for these other guys.

By the product rule, in total, we can do 4 distinct distribution in this condition.

Answer:

1. f(x) - 7

2. The lines do not have same x-intercept

3. a(x) = f(x+7)

4. b(x) = f(x-3)

5.  c(x) = f(x) + 5 and c(x) = f(x+5) are two functions that can represent c(x)

6. a. g(x) = f(x-8)

   b. Slope of g(x) = 1                                        

   c. y-intercept = (0, -8)

7. a. p(x)=f(x+6) is vertical transformation of f(x) = x. f(x) is the parent function.

   b.(please check explanation section.)

For the second page, here are the answers

5.

a. False

The slope of f(x) will be steeper than m(x)

b. False

The y-intercept doesn't change due to multiplication of 3/5

6. C. h(x) = 3f(x-5)

7. d(x) = 1/4 f(x) + 9

8. Erika: c(x) = 4f(x) + 4 is the first graph

Landry: c(x) = -4f(x) + 3 is the second graph

Step-by-step explanation:

1. f(x) - 7 = x - 7 ( y intercept is translated down when g(x) = x - k )

2. The lines do not have same x-intercept. ( x-intercept of f(x)=x is (0,0) and that of f(x-10) is (0,10)

3. a(x) = f(x) + 7 = x + 7 = f(x+7)

4. b(x) = f(x) - 3 = x - 3 = f(x-3)

5. c(x) = f(x) + 5 = x + 5 = f( x+5)

   c(x) = f(x) + 5 and c(x) = f(x+5) are two functions that can represent c(x)

6. a. g(x) = f(x) - 8 = x -8 = f(x-8)

    b. Slope of g(x) = Slope of f(x)      

         Slope of f(x) =  d(f(x)/dx = dx/dx = 1

          Therefore Slope of g(x) = Slope of f(x) = 1      

c. y-intercept = (0, -8)       (In this case The y-intercept of g (x)=f(x-8) is translated down as -8<0 by 8 units.)

7.  b. Look at the graph for part b

Now for the second page, here are the steps

look at the pictures, they show the steps and solution

Answer:

Clear the fraction first which means multiply both side by the reciprocal (2)

2a = bh

Divide both sides by b since you are solving for h

Your answer is 2a/b = h
