If the x value is reapeted in a set of x values, is it a function?when finding a function do you loko at x values or y values?

Answers

❅☃ If the x value is repeated it is considered a non-function.
So if we had x values of:
2
3
6
it is a function
but if we had 
3
6
6
it is a non function because the 6 was repeated
❅☃ Yes, you have to look at the x values, if you do not look at the x values, then you cant determine the functions.
yes it is still a function it just wont be linear

if 6 banannas are $1.50 and 5 oranges are $3.00 how much would it cost if i buy 2 banannas,and 2 oranges.

Answers

2 bananas are $0.50
2 oranges are $1.20
find cost of 1 of each
1.50/6=0.25 per banana
3.00/5=0.60 per orange

2*0.25+2*0.60=0.50+1.20=1.70

total cost is $1.70

Write a whole number and a fraction greater than q to name the part filled. think: 1 carton = 1

q=4 wholes because it would be 12/3 and u reduce it by 3/3 and you get 4/1 and that's a improper fraction so it will be 4 wholes

3. IF ON = 5x - 7, LM = 4x +4, NM = x - 7, and OL = 3y – 4, find the values of x and y for which LMNO mustbe a parallelogram. The diagram is not to scale.
N CH-7=5X

Answers

Answer:

x = 11 and y = (8)/(3)

Step-by-step explanation:

If LMNO is a parallelogram then it's opposite sides will be equal.

So, LM = ON

⇒ 4x + 4 = 5x - 7

⇒ x = 11

Now, MN = OL  

⇒ x - 7 = 3y - 4

⇒ 11 - 7 = 3y - 4 {Since we already have, x = 11}

⇒y = (8)/(3) (Answer)

A customer returned a light fixture to the store in exchange for a $52 light fixture and three gallons of paint at $29 each.He had to pay $112.How much had he paid for the first light fixture

Answers

The cost of the first light fixture is $27.

Given that, a customer returned a light fixture to the store in exchange for a $52 light fixture and three gallons of paint at $29 each.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the cost of first light fixture be x.

Now, x=52+3×29 - 112

=52+87 - 112

= 139 - 112

= 27

Therefore, the cost of the first light fixture is $27.

$29 times 3 is $87

$112-$87 = $25

52-25= 35

The customer paid $35 for the first light fixture. I think.
