Write the equation for the following table: X. Y. 0 3 1 7 2 11 3 15

Vanyuwa [196]

Answer:

$y = 4x + 3$

Step-by-step explanation:

The equation of the table of values given can be written as $y = 4x + 3$ .

When x = 0,

$y = 4(0) + 3$

$y = 0 + 3 = 3$ this corresponds with what we have in the table above.

Let's try another.

When x = 2,

$y = 4(2) + 3$

$y = 8 + 3$

$y = 11$

This also corresponds with what we have in the table.

Therefore, the equation of the table given is $y = 4x + 3$ .

Someone help pleaseeee

qaws [65]

Answer:

Part A = D

Part B = 5 and 50

Step-by-step explanation:

Part A:

area = 5*4x = 20x

so, $100 \leq 20x \leq 1000$

Part B:

to leave it only by x, you divide both sides by 20

100/20 = 5, 1000/20 = 50

which $5\leq x\leq 50$
