Please help please help please ​
yKpoI14uk [10]

Answer:

As per Given Information

→ ∠AOB = 7x-99°

→ ∠COD = 2x + 1°

we have to find the value of x .

∠AOB = ∠COD ( Vertically Opposite Angle)

On putting the value we obtain

➺ 7x-99° = 2x + 1°

➺ 7x -2x = 1° + 99°

➺ 5x = 100°

➺ x = 100°/5

➺ x = 20°

So, the value of x is 20° .

PLEASE HELP! The table represents a function.
Svetradugi [14.3K]

Answer:

The correct option is A. The rate of change in the function y=2x+5 is greater than the rate of change of the function represented in the table.

Step-by-step explanation:

The slope intercept form of a line is

y=mx+b

Where, m is slope and b is y-intercept.

The given equation is

y=2x+5

Therefore the slope of the equation is 2.

The formula to find the slope

m=\frac{y_2-y_1}{x_2-x_1}

The two points from the table are (-1,0) and (2,3).

Slope of the function that is represented in the table is

m=\frac{3-0}{2-(-1)} =\frac{3}{3}=1

Therefore, the slope of the function that is represented in the table is 1.

Since 2>1, therefore the rate of change in the function y=2x+5 is greater than the rate of change of the function represented in the table. Option A is correct.
