y = 2x

Step-by-step explanation:

The linear functions are given by:

y = mx+b

To find the slope, we have to find the change in x and y

The change in x is:

-14-(42) =-14+42 =28\\14+14= 28

The change in y is:

-28-(-84) = -28+84 = 56\\28-(-28) = 28+28 = 56

The slope is:

Slope = \frac{change\ in\ y}{Change\ in\ x}\\=\frac{56}{28}\\= 2

Putting slope in equation of linear function

y =2x+b

To find the value of b, we will put any pair of input and output in the slope-intercept form

So, putting (14,28)

28 = 2(14) + b\\28 = 28+b\\b = 28-28\\b = 0

Hence,

the linear equation for function is:

y = 2x

Find the length of side x in simplest radical form with a rational denominator.
devlian [24]

Answer:

x = 2√2

Step-by-step explanation:

This is a 45-45-90 triangle. This means that if the legs are x, then the hypotenuse is x√2.

In the case, the hypotenuse is already 4. So we have the equation:

x√2 = 4

Multiply both sides by √2

2x = 4√2

Divide both sides by 2

x = 2√2

If 2x and (4x+30) are complementary angles. find the angles. Please answer it it's urgent.
Alik [6]

Answer:

20 ,70

Step-by-step explanation:

Complementary angles sum up to 90

2x + 4x + 30 = 90

     6x  + 30 = 90

Subtract 30 from both sides

6x = 90 - 30

6x = 60

x = 60/6

x = 10

2x = 2*10 = 20

4x +30 = 4*10 +30 = 40 +30 = 70
