Mark recorded the growth of a plant over 8 weeks. The equation y=0.2x+2 represents the height y, in inches, after x weeks.
bezimeni [28]

The statements could be true are:

The height of the plant after week 3 was about 2.6 inches. ⇒ A

The height of the plant after week 9 was about 3.8 inches. ⇒ C

Step-by-step explanation:

Mark recorded the growth of a plant over 8 weeks

The equation y = 0.2x + 2, represents the height y, in inches, after x weeks

From the equation

  • 0.2 represents the rate of increasing of the height of the plant per week
  • 2 represents the initial height of the plant

∵ y represents the height of the plant after x week

∴ x is the number of the weeks

∵ y = 0.2x + 2

∵ x = 3

- Substitute x in the equation by 3

∴ y = 0.2(3) + 2

∴ y = 0.6 + 2

∴ y = 2.6

∴ The height of the plant after 3 weeks is 2.6 inches

∵ x = 9

- substitute x by 9 in the equation

∴ y = 0.2(9) + 2

∴ y = 1.8 + 2

∴ y = 3.8

∴ The height of the plant after 9 weeks is 3.8 inches

The statements could be true are:

The height of the plant after week 3 was about 2.6 inches.

The height of the plant after week 9 was about 3.8 inches.

In the diagram below of a parallelogram STUV, SV=x+3, VU 2x-1, and TU=4x-3. What is the length of SV?
Katena32 [7]

Answer:

SV=5\ units

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In a parallelogram opposites sides are parallel and congruent

so

In this problem

SV=TU ---> by opposite sides

substitute the given values

x+3=4x-3

solve for x

4x-x=3+3\\3x=6\\x=2

Find the length of SV

SV=x+3

substitute the value of x

SV=2+3=5\ units

The price of an item has dropped to $39 today. Yesterday it was
Kobotan [32]

Answer:

40% decrease

Step-by-step explanation:

First, let's find the value decrease of the item from yesterday to today

$65 - $39 = $26

That means that $65 was 100% of the price and decreasing it by 26 gets us to 39

We need to find the percentage of 39 in 65

39/65 = 0.6 or 60%

If 39 is 60% of 65, then there was a 40% decrease form 100%

To check we can calculate the percentage of 26 in 65:

26/65 = 40%

There was a 40% decrease
