The graph showing a function increasing at a constant rate is graph B.

How to determine a increasing or decreasing function in an interval?

In order to check the rate of rise of a function in an interval find the value of its derivative at all the points of that interval. If the values of derivatives are increasing then the function is increasing else it is decreasing.

The graphs A and B are given in the problem can be analysed one by one as follows,

Graph A,

In the interval [-∞,0], the slope of the function is decreasing.

And, in the interval [0,∞], the slope is increasing.

Thus, it is not increasing at a constant rate.

Graph B,

The function has the same slope in both the intervals [-∞,0] and [0,∞], which is positive.

It implies that the function is increasing at a constant rate.

Hence, the function shown in graph B is is increasing at a constant rate.

Which equation represents the solution of the equation 6x – 18 = 30?

Answers

Answer:

x=8

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

6*x-18-(30)=0

STEP 1:

Pulling out like terms

Pull out like factors :

6x - 48 = 6 • (x - 8)

STEP 2:

Equations that are never true:

Solve: 6=0

This equation has no solution.

Solving a Single Variable Equation:

Solve : x-8 = 0

Add 8 to both sides of the equation :

x = 8

2.) x - y = 6
2x = 12 + 2y

3.)1/2 x - y = 4
2y = x + 6

Answers

Answer:

2.) Infinitely many solutions

3.) No solutions

Step-by-step explanation:

To solve systems of equations graphically, you need to find where they intersect

2.) First put each equation in the form y=mx+b

x-y=6 -> y= x-6

2x=12+2y -> y= x-6

Then, graph each line

Since we have the same equation, the lines are on top of each other so there are infinitely many solutions as they intersect everywhere.

To check, plug a point in from the graph into both equations and you should get 0=0

3.) First put each equation in the form y=mx+b

1/2x-y=4 -> y=1/2x-4

2y=x+6 -> y=1/2x+3

Then, graph each line

Since the lines have the same slope but a different y intercept, the lines are parallel. Therefore, there are no solutions as they do not intersect.

To check your answer, you would one equation as the y in the other equation.

2(1/2x-4)=x+6, then solve for x

Then plug that x into the original equations, and you'll see they are not equal. Hope that helps!

Answer:

x = 119°

Step-by-step explanation:

y = 180 - 125

y = 55°

Sum of all the angles of quadrilateral = 360

x + 55 + 72 +114 = 360

x + 241 = 360

x = 360 - 241
