Answer:

M = 20; R = 40

Step-by-step explanation:

R = 2M

L = R + 10

L = 50

50 = R + 10

(Take away 10 from both sides)

50 - 10 = 40

40 = R

Remember, R = 2M

40 = 2M

(Divide both sides by 2)

40 / 2 = 20

20 = M

Answer:

f(x) = 2(4^x)

Step-by-step explanation:

Look at x = 0 in the table. It corresponds to f(x) = 2.

Now look at your answer:

f(x) = 4^x

Use x = 0:

f(0) = 4^0 = 1, but the table has f(0) = 2, so your answer is not correct.

Notice the numbers in the f(x) column. They are 2, 8, 32, 128.

Notice that they are 2 times perfect squares.

2 = 2 * 1

8 = 2 * 4

32 = 2 * 16

128 = 2 * 64

Try

f(x) = 2(4^x)

Now you have

f(0) = 2(4^0) = 2 * 1 = 2

f(1) = 2(4^1) = 2 * 4 = 8

f(2) = 2(4^2) = 2 * 16 = 32

f(3) = 2(4^3) = 2 * 64 = 128

and all the given points work.

Answer: f(x) = 2(4^x)

Answer:

Step-by-step explanation:

The best interpretation of P(3) = 12 is that if the length of the sides of the square is 3 units, then the perimeter of the square is 12 units.

A square is a two-dimensional figure that has four sides and all four sides are equal.

The area of a square is side²

We have,

The best interpretation of P(3) = 12 is that if the length of the sides of the square is 3 units, then the perimeter of the square is 12 units.

i.e

Since the function P is defined as the perimeter of the square in terms of its side length S,

We can substitute S = 3 into the function and get P(3) = 12.

This means that the sum of the four sides of the square when its length is 3 units is equal to 12 units.

Thus,

The best interpretation of P(3) = 12 is that if the length of the sides of the square is 3 units, then the perimeter of the square is 12 units.

Answer:

Step-by-step explanation:

I hate these, LOL

We're going to draw a triangle on the graph paper to solve this. (in theory)

The top point is at 2 on the x axis, and the bottom is at 6. That's a difference of 4. Draw a line from the top dot over 4 spaces, so a line dropped from there could go straight to the bottom dot. We'll call this line/side of the triangle a, and a = 4.

Then we drop the line from there (6, 4) down to the second dot at (6, -5). That line is 9 places long. We'll call this line/side of the triangle b, and b = 9.

(This is so much easier to draw than type, I'll attach a picture).

Then we connect the two dots diagonally to form line/side c of our triangle. This is the length we don't know.

The pythagorean theorem says a^2 + b^2 = c^2

So a = 4, b = 9, c is unknown for our triangle

(4)(4) + (9)(9) = c^2

16 + 81 = 97

The square root of 97 = 9.8488, so if they have you round, I would say 9.85

Sorry if this just confused you more.

Answer:

10x + 15

Step-by-step explanation:

x - 1 = 1 (2).

x + 4 x 10x + 15 / 2.445

x + 4 (2) / 2.445 = x1 - 4

10x + 15

Answer:

The product of 6x5/3 will be greater than 6 because the fraction 5/3 is greater than 1.

Step-by-step explanation:

Note: If any fraction which the numerator and denominator have the same number , for example 6/6 it will equal to 1. If the numerator overpasses the denominator, it will be more than 1.

Answer:

The width of the frame must be 12 inches (15in by 12in)

Step-by-step explanation:

Given

See attachment for painting and frame

Required

Determine the dimension of the frame

To do this, we make use of the following scale ratio.

[tex]Scale = Length : Width[/tex]

For the painting,

[tex]Scale = 20: 16[/tex]

For the frame,

[tex]Scale = 15: w[/tex]

Since she wants to maintain the same ratio; both scale must be the same.

i.e.

[tex]15 : w = 20 : 16[/tex]

Express as fraction

[tex]\frac{w}{15} = \frac{16}{20}[/tex]

[tex]\frac{w}{15} = 0.8[/tex]

Make w the subject

[tex]w = 15 * 0.8[/tex]

[tex]w = 12[/tex]

The width of the frame must be 12 inches i.e. 15in by 12in frame

Answer:

D

Step-by-step explanation:

D) The price was increased by 140% and then decreased by 85%.

Answer:

B

Step-by-step explanation:

The price was only increased by 40% because for example, the starting price was 100, then if you increased it by 140% or $140, then the price would be 240.

next, the decreased by 15% and not 85% because 100% - 15% = 85%
