Which of the following tables of value represent ordered pairs for the function f(x)=2x-1

1 answer:

6 0

Well without seeing the tables it is hard to answer. However, I will offer some help. f(x) is actually y. A function of x=y. So, now you have y=2x-1. Plug the x and y values in from the tables and make sure the equations are true with the given values (equal on both sides). For example, (2,3).. 3=2(2)-1...... 3=3. Hope this helps.

Answer:

y = 7x - 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (1, - 3)

m = $\frac{-3-4}{1-2}$ = $\frac{-7}{-1}$ = 7, thus

y = 7x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2, 4), then

4 = 14 + c ⇒ c = 4 - 14 = - 10

y = 7x - 10 ← equation of line

The area of the track will be 78501 m². The area of the track is equal to the area of the circle.

The space filled by a flat form or the surface of an item is known as the area.

The number of unit squares that cover the surface of a closed-form is the figure's area. Square meters and other similar units are used to measure area.

The area of the track is found as;

$\rm A=\frac{\pi}{4} d^2 \\\\ \rm A=\frac{3.14}{4} (100)^2 \\\\ A=7850 \ m^2$
