Answer:  (2,<u>-5</u>)

Step-by-step explanation:

The slope of the line formed by this set of number is 2 (y increases by 2 for every 1 increase in x).  The line has the form y = 2x + b.  Enter one of the data points to find b.

y = 2x + b  for (2,3)

3 = 2*2 + b

b = -1

The equation is y = 2x - 1

The missing value:  y =2*(-2) - 1

                                 y = -5

(2,-5)

PLEASE HELP!!!!!! The length of a rectangle is three times its width. If the perimeter of the rectangle is 56 cm, find its area.
Alexus [3.1K]

Step-by-step explanation:

l = length

w = width

l = 3w

perimeter p = 2l + 2w = 56

using the identity of the first equation

p = 2(3w) + 2w = 56

6w + 2w = 56

8w = 56

w = 7 cm

l = 3w = 3×7 = 21 cm

so, the area is

l×w = 21×7 = 147 cm²

second statement is false as heads probability is close to 70%

last 2 statements are true:

</span><span>The theoretical probability of tails is most likely 30%.

It is likely that the coin is not fair.

What is (43/7÷ x+32/9) ÷25/6=4/3
Fittoniya [83]

The value of x in the equation (43/7 ÷ x + 32/9) ÷ 25/6 = 4/3 is 43/14

<h3>How to solve for x in the equation?</h3>

The equation is given as:

(43/7 ÷ x + 32/9) ÷ 25/6 = 4/3

Rewrite as a product

(43/7 ÷ x + 32/9) x 6/25 = 4/3

Multiply both sides of the equation by 25/6

(43/7 ÷ x + 32/9)= 4/3 x 25/6

Evaluate the product

(43/7 ÷ x + 32/9)= 50/9

Rewrite the equation as:

43/7x + 32/9= 50/9

Subtract 32/9 from both sides

43/7x = 2

Multiply both sides by 7x

14x = 43

Divide by 14

x =43/14

Hence, the value of x in the equation (43/7 ÷ x + 32/9) ÷ 25/6 = 4/3 is 43/14
