The set of ordered pairs below is a relation. {(0.5,2), (1.5,5), (4.0,12), (6.5,15)} Which relation has the same domain as the given relation?

{(1,5),(2,2),(-3,15),(-8,12)}
{(0.5,1),(1.5,4),(4.0,11),(6.5,14)}
{(2,1,1),(5,2.2),(12,3.3),(15,4.4)}
{(-1,6.5),(-3,1.5),(-6,4.0),(-10,0.5)}​

Answers

Given:

The set of ordered pairs is

{(0.5,2), (1.5,5), (4.0,12), (6.5,15)}

To find:

Which relation has the same domain as the given relation?

Solution:

We know that, domain is the set of input values or x-values.

For the given set {(0.5,2), (1.5,5), (4.0,12), (6.5,15)}, the domain is

Domain={0.5, 1.5, 4.0, 6.5}

Similarly,

For {(1,5),(2,2),(-3,15),(-8,12)},

Domain = {1, 2, -3,-8}

For {(0.5,1),(1.5,4),(4.0,11),(6.5,14)},

Domain={0.5, 1.5, 4.0, 6.5}

For {(2,1,1),(5,2.2),(12,3.3),(15,4.4)},

Domain = {2, 5, 12, 15}

For {(-1,6.5),(-3,1.5),(-6,4.0),(-10,0.5)}​,

Domain = {-1, -3, -6, -10}

So, the relation {(0.5,1),(1.5,4),(4.0,11),(6.5,14)} has the same domain as the given relation.

Therefore, the correct option is B.

3(x-3) = -2x + 31 what is the value of x?

Answers

Answer:

x= 8

Step-by-step explanation:

1. Expand.

3x-9=-2x+31

2. Add 9 to both sides.

3x=-2x+31+9

3. Simplify  -2x+31+9  to -2x+40.

3x=-2x+40

4. Add 2x to both sides.

3x+2x=40

5. Simplify  3x+2x+5x.

5x=40

6. Divide both sides by 5.

x = 40/5

7. Simplify 40/5 to 8.

Mike compared the y-intercept of the graph of the function
f(x) = 5x + 12 to the y-intercept of the graph of the ilnear function that

intercept of f (x) is subtracted from the y-intercept of g (x)?
Х
1 3 5 6
g(x) 10 14 18 20

Answers

Answer:

-4

Step-by-step explanation:

Given function

f(x) = 5x + 12

From the table we get the function g(x), use pairs (1, 10) and (3, 14)

The slope:

m = (14 - 10)/(3 - 1) = 4/2 = 2

The y-intercept:

10 = 2(1) + bb = 10 - 2b = 8

The function g(x) is found as:

g(x) = 2x + 8

The y- intercept of f (x) is subtracted from the y-intercept of g (x):

8 - 12 = -4

Answer:

(the answer is • -4)

Answer:

Step-by-step explanation:

Since this is a test/homework I'll give a hint.

For a linear equation, you have no idea what x and y is, but thats ok! The test itself has already given you 4 options, so you can just input the x/y coordinates, and if they fit, good for you! If they don't, you may need to try again. There are other more complex and faster ways, but they are (a) more complex.

Hope this helps!

Over which interval on the x-axis is there a negative
rate of change in the function?
O-2 to -1
O -1.5 to 0.5
O 0 to 1
O 0.5 to 1.5

Answers

There is a negative rate of change in the function In the interval (-2,-1) on the x-axis.

What is the average rate of change between two coordinates?

The slope of the straight line connecting two points is the average rate of change between those two coordinates.

We can infer from the graph,

the slope of the straight line connecting these points is negative in the range of -2 to -1.

As a result, the function's rate of change over this interval is negative.

Hence, In the interval –2 to –1 there is a negative rate of change in the function.
