What is the negative x-intercept of the quadratic function represented by
y = (2x + 8) (3.2 – 1)?

Answer:

n ≥ 12.5 weeks

Step-by-step explanation:

Weekly savings = at least $16

n = number of weeks

At least in inequality means ≥

16n ≥ 200

n ≥ 200/16

n ≥ 12.5 weeks

12.5 weeks until she has saved $200

Answer:

The gaming system was on sale for 20% off

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%

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

Answer:

The number of weeks and total number of books increase together at a constant rate.

As the number of weeks increases by 1, the total number of books increases by 1.

The common difference between the number of weeks and total number of books is 6.

Doubling the number of weeks also doubles the total number of books.

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:

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:

4(x + 8) is equivalent to 4x + 32, 4x + 8(4),

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

We can sue the pythagorean theorem to verify. 15^2+36^2 should equal the longest side squared or 39^2. If we plug in the numbers, it checks out!

Answer:

true

Step-by-step explanation:

we can use the Pythagorean theorem to verify if the sum of the squares built on the legs is equal to the square built on the hypotenuse

36^2 + 15^2 = 39^2

1296 + 225 = 1521

1521 = 1521
