Answer:

<em>The domain of R is {-3,-2,1,-3,0}</em>

<em>The range of R is: {2,1,3}</em>

<em>The relation R is not a function</em>

Step-by-step explanation:

Relations and Functions

We are given the ordered pairs of a relation, let's call it R:

R={(-3, 2), (-2, 2), (1, 2), (-3, 1), (0, 3)}

The domain of R is the set of values that relate to 1 or more elements from the range.

The domain of R is {-3,-2,1,-3,0}

The range of R is: {2,1,3}

Note the value 2 is repeated in the second set, but it's reported only once as part of the Range.

A relation is a function if each element of the domain appears in only one ordered pair, or relates to a single element in the Range.

The relation R is not a function, because the ordered pairs (-3, 2) and (-3, 1)

map the element -3 twice.

what is the equation, in slope-intercept from, of the line that is perpendicular to the line y - 4 = -2/3 (x -6 ) and passes thr
Ne4ueva [31]

Turn y - 4 = -2/3(x - 6) into a linear equation.

y - 4 = -2/3(x - 6)

y - 4 = -2/3x + 4

 +4                +4

y = -2/3x + 8

The equation that is perpendicular to y = -2/3x + 8 is y = 3x + 4 as shown in the image below using a graph.

How many social security numbers are available if the only restriction is that the number 000-00-0000 cannot be assigned?
harkovskaia [24]
Each digit can be 0-9 ( 10 numbers)
 there are 9 numbers in a social security number

multiply 10 nine times:
10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 =  1,000,000,000 ( 1 billion) possibilities.
 
 the restriction is it can't be all zeros so subtract 1 from the total
 1,000,000,000 - 1 = 999,999,999 combinations

I take 8th grade honors math but i straight up cant figure this out
Rufina [12.5K]

The price of the fries would be $2.50, the price of the drink would be $2.50, and the price of the cheeseburger wold be $7.50.

We can write a set of equations to represent the prices, if 'f' is fries, 'd' is drink, and 'c' is cheeseburger:

c = 3f

f = d

Using these equations, we can then write out the sum of the items also, as it would be c + f + d = 12.50, but as we know that c = 3f and d = f, we can write it as 3f + f + f = 12.50, and then solve:

3f + f + f = 12.50

5f = 12.50

÷ 5

f = $2.50

Now that we know the price of the fries, we know that the price of the drink is the same, so the drink is also $2.50. Then, we can multiply 2.50 by 3 as we know that the cheeseburger is 3 times the cost of the fries, and 2.50 × 3 = 7.50.

I hope this helps!

Slope = 4<br> Y-intercept = -1
umka2103 [35]

Answer:

y = 4x -1

Step-by-step explanation:

You use the equation y = mx + b

m is the slope, so you just substitute 4 for m, and b is the y-intercept, so you substitute -1 for b
