Answer:

D

Step-by-step explanation:

A unit rate is basically which one increases more as time goes on. Now. to make it easier let me explain visual.

You have 50 apples at the start and every hour you get 200 more apples, sweet!

Now let's look at the chart.

The first one is 200x+100, this is wrong since this has a better start but you don't get as much apples.

Same goes for the B and C. The only one that would make sense is D since you're also adding 10 more apples for each one you increase.

because y² + 4y + 5 = (y+2)² + 1 > 0, ∀ y ∈ R

=> y² + 4y + 5 = 0 is unreasonable

=> no solutions

∵ (a×b)×c=a×(b×c) [by associative law of multiplication.]

Answer:

Yes

Step-by-step explanation:

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8. and that is something Very similar.

Given:

Height of box = (x-2)

Volume of box = [tex](x^3-8)[/tex]

To find:

The expression for the base area.

Solution:

We know that,

Volume of a box(V) = Base area(B) × Height(h)

[tex]V=Bh[/tex]

[tex]\dfrac{V}{h}=B[/tex]

On substituting the given values, we get

[tex]B=\dfrac{x^3-8}{x-2}[/tex]

[tex]B=\dfrac{x^3-2^3}{x-2}[/tex]

[tex]B=\dfrac{(x-2)(x^2+2x+2^2)}{x-2}[/tex]   [tex][\because a^3-b^3=(a-b)(a^2+ab+b^2)][/tex]

[tex]B=x^2+2x+4[/tex]

So, the base area is [tex]x^2+2x+4[/tex].

Therefore, the correct option is B.

Step-by-step explanation:

Answer:

slope is negative go down one right 2

Answer:

465 miles

Step-by-step explanation:

D = r * t

D = 62 * 7.5 = 465 miles

Answer:

465

Step-by-step explanation:

We know that the rate is 62 mph. The time is 7.5 h.

Plug it into the existing equation:

D = r × t becomes D = 62 × 7.5

Just stick that into a calculator to get 465.

Answer:

The easier way to solve this is to find the two points in the coordinate axis, and just draw a line that passes through the two points.

But let's be more complete:

Let's find the equations for each line:

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

1) Here the points are (2,2) and (4,5)

then the slope is:

a = (5 - 2)/(4 - 2) = 3/2

y = (3/2)*x + b

And to find the value of b, we just replace the values of one of the points in the equation, in this case i will use (2, 2)

2 = (3/2)*2 + b

2 = 3 + b

2 - 3 = b

-1 = b

y = (3/2)*x - 1

2) Here the points are (0,1/2) and (2,3/2)

then the slope is:

a = (3/2 - 1/2)/(2 - 0) = 1/2

y = (1/2)*x + b

And to find the value of b, we just replace the values of one of the points in the equation, in this case i will use (0, 1/2)

1/2 = (1/2)*0 + b

1/2 = b

y = (1/2)*x + 1/2

3) Here the points are (-1,2) and (5,0)

then the slope is:

a = (0 - 2)/(5 + 1) = -1/3

y = (-1/3)*x + b

And to find the value of b, we just replace the values of one of the points in the equation, in this case i will use (-1, 2)

2 = (-1/3)*-1 + b

2 = 1/3 + b

2 - 1/3 = b

5/3 = b

y = (-1/3)*x + 5/3

4) Here the points are (-5,-3) and (-3,5)

then the slope is:

a = (5 + 3)/(-3 + 5) = -4

y = -4*x + b

And to find the value of b, we just replace the values of one of the points in the equation, in this case i will use (-3, 5)

5 = -4*-3 + b

5 = 12 + b

5 - 12 = b

-7 = b

y = -4*x - 7

Now that we have all the equations, we can find the graphs.

(4) green

Answer:

a. 5

b. 1

c. 132

d. -2

Step-by-step explanation:

a. The square root of 4 is 2, the absolute value of -3 is 3. 2 + 3 = 5

b.  4 - (-3) / -7 = 7/ -7 = 1

c. 2 * 4^3 = 128 + (-3) - (-7) = 132

d. 2 (-7 + 3) = -8, square root to the third power of -8 is -2

An equation which models the relationship between X and Y is

y = 54.5x

The correct answer is option (D) y = 54.5x

What is equation?

"A mathematical statement which contains an equal symbol between two algebraic expressions that have the same value."

From given data we can observe that,

163.5/3 = 54.5                           ...................(1)

327/6 = 54.5                              ...................(2)

599.5/11 = 54.5                          ...................(3)

From (1), (2) and (3),

y/x = 54.5

⇒ y = (54.5)x

Therefore, an equation which models the relationship between X and Y is y = 54.5x

The correct answer is option (D).

Answer:

x = -3/11

Step-by-step explanation:

First, distribute the -3 and 12 within the parenthesis

12 - 9x + 15 = 24x + 12

Now, combine like terms

3 - 9x = 24x + 12

Subtract 24x from both sides of the equation

3 - 33x = 12

Subtract 3 from both sides of the equation

- 33x = 9

Divide both sides by -33

x = -9/33

-9/33 can be simplified to -3/11, so the answer is

x = -3/11
