Answer:

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.

Answer:

18.67 m/s²

Step-by-step explanation:

a = ∆v/ t

a= v - u/t

a = 2.8 - 0 / 0.15

a = 2.8 / 0.15

a = 18.67 m/s²

Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth.

sasho [114]

Answer:

The final answers are x = 5 OR x = -1.

Step-by-step explanation:

Given the equation is x^2 -5 = 4x

Rewriting it in quadratic form as:- x^2 -4x -5 = 0.

a = 1, b = -4, c = -5.

Using Quadratic formula as follows:- x = ( -b ± √(b² -4ac) ) / (2a)

x = ( 4 ± √(16 -4*1*-5) ) / (2*1)

x = ( 4 ± √(16 +20) ) / (2)

x = ( 4 ± √(36) ) / (2)

x = ( 4 ± 6 ) / (2)

x = (4+6) / (2) OR x = (4-6) / (2)

x = 10/2 OR x = -2/2

x = 5 OR x = -1

Hence, final answers are x = 5 OR x = -1.

Graph the linear equation with 3 points

barxatty [35]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$x-y=1$

To graph the line find the intercepts

step 1

Find the y-intercept (value of y when the value of x is equal to zero)

For x=0

substitute in the linear equation

$0-y=1\\y=-1$

The y-intercept is the point (0,-1)

step 2

Find the x-intercept (value of x when the value of y is equal to zero)

For y=0

substitute in the linear equation

$x-0=1\\x=1$

The x-intercept is the point (1,0)

step 3

Find a third point

Note: It is important to specify that two points are sufficient to draw a line

assume the value of x=5

substitute in the linear equation and solve by y

$5-y=1\\y=5-1\\y=4$

The third point is (5,4)

step 4

Plot the points and connect them to graph the line

see the attached figure
