Answer:

I hope it will be useful.

Answer:

Therefore, the rate of change of function 2 is 3 more than the rate of change of function 1.

Hence, option C is true.

Step-by-step explanation:

Function 1

A horizontal straight line is drawn joining the ordered pairs (0, 3) and (4, 3).

Given the points

It means

at x = 0, y = 3

at x = 4, y = 3

Since the y-values are same, it means the points lie on a horizontal.

The rate of change or slope of a horizontal line is zero because it does not rise vertically ( i.e. y₁ - y₂ = 0).

Therefore, the rate of change of function 1 = 0

Function 2

y = 3x+1

comparing with the slope-intercept form

y = mx+b      

here m is the rate of change or slope and b is the y-intercept

so the rate of change of the function 2 = m = 3

Conclusion:

Therefore, the rate of change of function 2 is 3 more than the rate of change of function 1.

Hence, option C is true.

Answer:

  3)  1,440

Step-by-step explanation:

The dimensions of the prism can be expressed in terms of the cube dimensions.

  1 2/6 inches = 8/6 inches = 8×(1/6 inch)

  5/6 inch = 5×(1/6 inch)

  6 inches = 36/6 inches = 36×(1/6 inch)

So, the volume of the prism in terms of small cubes is ...

  8×5×36 = 1,440 . . . small cubes

Answer:

Because if you add 18x to both sides of the equation, you get 0 = -18

Step-by-step explanation:

When you combine like terms in the equation, you get -18x = -18x - 18. After adding 18x to both sides, you have 0 = -18. This is not true, which means that there are no solutions to the equation.

Answer:

x=3

Step-by-step explanation:

log (x^2 - 1) - log (2x + 2) = 0

Add log (2x + 2) to each side

log (x^2 - 1) = log (2x + 2)

Since the logs with the same base are equal the x^2 -1 must equal 2x+2

x^2 -1 = 2x+2

Subtract 2x+2 from each side

x^2 -1 -2x-2 = 2x+2 -2x-2

x^2 -2x-3 = 0

Factor

What number multiplies to -3 and adds to -2

-3 *1 =-3

-3+1 =-2

(x-3) (x+1) =0

Using the zero product property

x-3 =0   x+1 =0

x=3  x=-1

Check to see if solutions are valid

x = -1

log ((-1)^2 - 1) - log (2*-1 + 2) = 0

log(0) - log 0 = 0

Log 0 is undefined  x =-1 not a valid solution

x = 3

log ((3)^2 - 1) - log (2*3 + 2) = 0

log(8) - log 8 = 0

valid

Answer:

given below

Step-by-step explanation:

These are fractions problems .

If you have 12 eggs and you need 1/6 then

12* 1/6= 12/6= 2 eggs

Similarly if you need 1/3,1/4, 1/2

12 * 1/3= 12/3= 4 eggs

12 * 1/4 = 12/4= 3 eggs

12 * 1/2 = 6 eggs

These can be drawn in sets of 12.

from the picture we see that dividing the 12 eggs in two parts and coloring one part gives 6 eggs.

Similarly dividng the 12 eggs in three parts and coloring one part gives 4 eggs.

The fractions 1/3,1/4,1/2 or 1/6 means dividing the 12 eggs into 3,4,2, or 6 parts and obtaining 1 part out of it.

------------------------

The y value in the table gets multiplied by 4 every time the x value goes up by 1. You can check your work using the values in the table given to you. 0.25 times four is 1. 1 times four is 4, and so on as the table goes.

The ratio would be written as 1:4

Answer:

3i[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex] and [tex]\sqrt{-1}[/tex] = i

Given

[tex]\sqrt{-27}[/tex]

Answer:

$100

Step-by-step explanation:

From the question, we are given the following

Rental price of the truck

percentage off coupon = 50%

Required

Sale tax of the truck rental

Sale tax of the truck rental = 50% of the truck price

Sale tax of the truck rental = 50% of $200

Sale tax of the truck rental = 50/100 * 200

Sale tax of the truck rental = 0.5 * 200

Sale tax of the truck rental = $100

Hence the sale tax of the truck rental is $100

Answer:

$100.7

Step-by-step explanation:

Total cost

= cost of item + amount of sales tax

= 95 + 6% of 95

= 95 + 0.06*95

= 95 + 5.7

= $100.7

Answer:

Since the sales tax is 6%, the object will cost 1.06 (100% + 6%) times the original value.

1.06 × $95.00 = $100.70

The object will cost $100.70.

Or the answer should simply be

3x + 4y = 10

Answer:

see explanation

Step-by-step explanation:

To solve, choose a value of x or y, substitute into the equation and evaluate for the other variable.

Choose x = 2, then

3(2) + 4y = 10

6 + 4y = 10 ( subtract 6 from both sides )

4y = 4 ( divide both sides by 4 )

y = 1

Thus (2, 1 ) is a solution to the equation

Answer:

Value of p = 30
