Yosef found this relationship between the quantities in the table.

Mkey [24]

Yosef should have multiplied the x-values by 80 to get the y-values.

<h3>Functions and tables</h3>

Tables are told used to arrange ungrouped data.

From the given table, we can find the equation by using the coordinate points (1, 80) and (1, 160)

<h3>Find the equation of the line</h3>

The standard equation of a line is y = mx + b

m is the slope

b is the y-intercept

Slop = 160-80/2-1

Slope = 80

For the y-intercept

160 = 80(2) + b

b = 0

The required equation is y = 80x

This means that Yosef should have multiplied the x-values by 80 to get the y-values.

The area of a circle is 286 cm2. Use the π button on your calculator for π in your calculations.

hram777 [196]

Answer:

9.54 cm

Explanation:

area = πr^2

286 cm^2= πr^2

=>πr^2= 286 cm^2

=>r^2= 286÷π

=>r= √286÷π

: 9.54. m

circumference=2πr

=> circumference=2×π×9.54

=60 cm

Which linear inequality could represent the given table of values?

liubo4ka [24]

Answer: The answer is (B) y ≤ –2x + 3 .

Step-by-step explanation: We are to select the correct linear inequality that could represent the table of values given in the question.

If (x, y) = (-4, -1), then

$y=-1,\\\\-2x+3=-2\times(-4)+3=8+3=11.$

So, y < -2x + 3.

If (x, y) = (-2, 4), then

$y=4,\\\\-2x+3=-2\times(-2)+3=4+3=7.$

So, y < -2x + 3.

If (x, y) = (3, -3), then

$y=-3,\\\\-2x+3=-2\times 3+3=-6+3=-3.$

So, y = -2x + 3.

If (x, y) = (3, -4), then

$y=-4,\\\\-2x+3=-2\times 3+3=-6+3=-3.$

So, y < -2x + 3.

Therefore, we have y is either less than or equal to (-2x + 3).

Thus, y ≤ –2x + 3 and (B) is the correct option.
