Identify the domain of the function shown in the graph.

Answers

Answer:

x is all real numbers

Step-by-step explanation:

Domain is the set of all values of x for which the function is defined.

Range is the set of all y values for which the function is defined

From the given graph , we have graph for all values for x.

The graph is continuous and smooth. there is no restriction for x.

So , the domain is all real numbers

x is all real numbers

C. x is all real numbers

Which ratio can be used to form a proportion with the given ratio? 7 to 12

A.
8 to 13

B.
10 to 15

C.
14 to 19

D.
21 to 36

Answers

7 / 12 = 0.583333333

Divide them all to see which one equals 0.583333333.

A.

8 / 13 = 0.615384615

B.

10 / 15 = 0.666666667

C.

14 / 19 = 0.736842105

D.

21 / 36 = 0.583333333

Therefore, your answer is D.
D.
If you multiply both numbers in the given proportion by 3, you get answer D:
7 x 3 = 21
12 x 3 = 36.
Because you can multiply both of the numbers in the given ratio by the same number (3) to get the ratio in answer D, they are a proportion.

What is the equation of the line that passes through (-6,-6) and (12,9)?

Answers

The correct answer for the question that is being presented above is this one: 

(1) Get the slope (m)
m = (y1 - y2) / (x1 - x2)
m = (-6 - 9) / (-6 - 12)
m = -15 / -18
m = 5/6

(2) Get the x-intercept (b)
y = mx + b
-6 = (5/6)(-6) + b
-6 = -5 + b
b = -1

(3) Form the equation
y = mx + b
y = (5/6)x -1

So the equation is y = (5/6) x - 1.
