Answer:

(0,4) vertex and (1,3) another pt

Step-by-step explanation:

The parabola has been shifted up 4 units from parent function (there is also a reflection)...but we only really care about the shift 4 units up from (0,0) for our vertex... Our vertex is (0,4)

Now just plug in another number to find another point...let's do x=1

Plug in you get -1^2+4=-1+4=3 so another point is (1,3)

If the function is y = 4.5x. Then the rate of change of the function expressed as a unit rate will be 4.5.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A bike rental company charges a fee per hour.

The charge, in dollars, is the same each hour.

The ordered pairs (3, 13.50) and (5, 22.50) represent the corresponding hours, x, and cost, y.

Then the linear equation is given as

$\begin{aligned} \rm y - 22.5 &= \rm \dfrac{22.5 - 13.5}{5 - 3} (x- 5)\\\\\rm y - 22.5 &= \rm 4.5x - 22.5\\\\\rm y &= \rm 4.5x \end$

Then the rate of change of the function expressed as a unit rate will be

$\rm \dfrac{dy}{dx} = \dfrac{d}{dx} (4.5x )\\\\\dfrac{dy}{dx} = 4.5$

Using a metric line as taught in your lesson, convert the following metric measurement. (Remember to use the same number of sign

weqwewe [10]

Answer:

Option B.

Step-by-step explanation:

We need to express 505 kL in L.

Here, kL means kiloliter and L means liter.

We know that

1 kL = 1000 L

Using this conversion we can easily convert 505 kL in L.

Multiply both sides by 505.

505 × 1 kL = 505 × 1000 L

505 kL = 505,000 L

The value of 505 kL can be expressed as 505,000 L.

Therefore, the correct option is B.

What are the next three terms of each sequence?5,7.5

leva [86]

Answer:

The next three terms are 10, 12.5 and 15

Step-by-step explanation:

I. As you can see 5 and 7.5 is came from 5, 5 + 2.5

So given y = 5 + 2.5( x - 1 ) when y is output, x is term

II. Perform x = 3, 4, 5

So y = 5 + 2.5( 3 - 1 )

= 5 + 5

3rd = 10

y = 5 + 2.5( 4 - 1 )

= 5 + 7.5

4th = 12.5

y = 5 + 2.5 (5 - 1)

= 5 + 10

5th = 15
