Answer:

  C.  graph Y

Step-by-step explanation:

Starting with f(r) = -3r +3, the inverse function can be found from ...

  r = f(y)

  r = -3y +3

  r -3 = -3y

  (r -3)/-3 = y

  y = -1/3r +1

The inverse function will have a slightly negative slope and a y-intercept of 1. This matches graph Y.

Answer:

Answer:

I got 4x=5y sorry if i'm wrong

Answer:

To find the inverse you switch x and y

Step-by-step explanation:

3y-4x=6

So 3y = 4x+6

and Y = 4/3x + 2

Answer:

y=(6-3x)/-4

Step-by-step explanation:

to get the inverse we make y the subject of the equation

3x-4y=6

-4y=6-3x

y=(6-3x)/-4

Step-by-step explanation:

There are 24 desks because 4 rows multiplied by 6 desks in each row = 24 desks.

Answer:

D. $120

Explanation:

P= principal amount, which is $2000 in this case

R= interest rate. In this case, it's 3% per year (or 0.03 in decimal form)

T= time, which in this case is 2.

To find the simple interest, we multiply 2000 × 0.03 × 2 to get 120.

I hope this helped! :)

Answer: 120 is the right answer i think im not sure

Step-by-step explanation:

Answer:

s = -1

Explanation:

s − (−20) = 19

[ Simplify both sides of the equation ]

s + 20 = 19

[ Subtract 20 from both sides ]

s + 20 − 20 = 19 − 20

s = −1

Step-by-step explanation:Im not tottally sure

Answer:

15) For a regular polygon of N sides, the measure of one interior angle is:

A = (N -  2)*180°/N

In this case, the figure has 11 sides, then we have N = 11, and the measure of each interior angle will be:

A = (11 - 2)*180°/11

A = 9*180°/11 = 147.27°

Rounding to the first decimal after the decimal point, we get:

A = 147.3°

Then the correct option is B.

16) We know that the length of all the sides of a square is the same.

In the image, we can see that the length of the right side is 4, and the length of the top side is 2x + 4

And those lengths must be the same, then we have the equation:

2x + 4 = 4

subtracting 4 in each side of the equation we get:

2x + 4 - 4 = 4 - 4

2x = 0

The only solution for this equation is x = 0.

Then the correct option is C

Answer:

x=0, y=0

Step-by-step explanation:

① Label the 2 given equations.

x -2y= 0 -----(1)

3x +y= 0 -----(2)

② Make x the subject of formula in equation (1).

From (1): x= 2y -----(3)

③ Substitute equation (3) into (2):

3(2y) +y= 0

Expand:

6y +y= 0

Simplify:

7y= 0

y= 0

④ Find x.

Subst. y=0 into (3):

x= 2(0)

x= 0

Answer:The advantage of the debt snowball is that it helps build motivation for debt repayment. The debt snowball method involves paying off the smallest debts first to get them out of the way before moving on to bigger ones. It's not easy to get excited about debt repayment.

Step-by-step explanation:

Answer:

18n+9 i think

Step-by-step explanation:

The number which is 4 x 10^3 times equal to the number 16 x 10^3 after is number 4.

Product is the resultant number which is obtained by multiplying a number with another. Let a number a is multiplied by number b. Then the Product of these two number will be,

[tex]P=a\times b[/tex]

Here, (a, b) are the real numbers.

The 4 x 10^3 times a number is equal to the number 16 x 10^3 Let suppose this number is n. Thus,

[tex]4\times10^{3}\times n=16\times10^{3}[/tex]

Divide both side of the equation with 4 x 10^3 as,

[tex]n=\dfrac{16\times10^{3}}{4\times10^{3}}\\n=\dfrac{16}{4}\\n=4[/tex]

Hence, the number which is 4 x 10^3 times equal to the number 16 x 10^3 after is number 4.
