From the table, y varies directly as x. Therefore,  the constant of variation is k = 2 and y = 2x.

<h3>How to find a direct variation?</h3>

For direct variation,

y ∝ x

Therefore,

y = kx

where

  • k = constant of proportionality

Hence,

(-2, -4)

-4 = -2k

k = -4 / -2

k = 2

(-4, -8)

y = -4(2) = -8

Therefore,

k = 2 and y = 2x

What is a fraction for 0.8
Leni [432]

Answer: 4/5

Step-by-step explanation: Using the place value chart, we can see that 0.8 means eight-tenths which can be written as the fraction 8/10. Since 8/10 is not in lowest terms, we need to divide both the numerator and denominator by the greatest common factor of 8 and 10 which is 2 to get 4/5.

Therefore, 0.8 can be written as the fraction 4/5.

Angle DCA is 120°. What percent of the circle's area does this section represent?
dolphi86 [110]
A circle is 360

so we're going to set up a proportion

120        x
------ = ------
360       100

then cross multiply and divide

120 times 100=12000/360=33.3333333

so the answer is C. 33

Tamara is planting bushes around her house. So far today she has planted 5 bushes and she wants to plant at least 12 bushes toda
bixtya [17]

Answer:

b+5\geq 12

Step-by-step explanation:

Given:

Number of bushes planted = 5

Minimum number of bushes to be planted = 12

Let the number of bushes planted after planting 5 bushes be b.

Since, Tamara has already planted 5 bushes, total number of bushes planted is given as:

b+5

Now, as per question, total number of bushes should be 12 or greater than 12.

Therefore, b+5\geq 12.
