The function shown in the graph is
pshichka [43]

Answer:

Linear function

y = 2x - 1

Step-by-step explanation:

This is a linear function because the line is straight, having no curved.

The equation for a linear graph is y=mx + b.

x and y represent points on he graph.

"m" represents the slope of the graph. Reading from left to right, if a positive slope, then the graph continues upward. If negative, then it's a graph down downwards.

"b" represents the y-intercept, when the graph hits the y-axis. It's also the initial value.

In the photo, we can see the y-intercept is (0, -1).

Slope is calculated by rise over run. Choose two random points on the graph. Count the "rise", or how many vertical units are between the points. If the point on the right is lower than the point on the left, the rise is negative. Count the "run", which is the number of horizontal units between the points.

For the point (0, -1) and (3, 5).

m = rise/run

m = 6/3

m = 2

Substitute m=2 and b= -1 into the equation of a line.

y = 2x - 1

Select the correct answer. What is the definition of csc θ ?
OleMash [197]

Answer:

A. csc θ=1/sinθ

Step-by-step explanation:

From SOHCAHTOA,

sine = opposite/ hypotenuse

Cos = adjacent / hypotenuse

Tan = opposite / adjacent

In a right angled triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the side opposite the angle. This is the inverse of sine , therefore:

Csc Ф = 1/ sinФ

Factorise fully -x - 8
natta225 [31]

Answer:

x = -8 please mark brainliest

Step-by-step explanation:

Pull out like factors :

  -x - 8  =   -1 • (x + 8)

Equation at the end of step  1  :

Step  2  :

Solving a Single Variable Equation :

2.1      Solve  :    -x-8 = 0

Add  8  to both sides of the equation :

                     -x = 8

Multiply both sides of the equation by (-1) :  x = -8
