Answer:
Answer: Domain is the set of all possible input for which the relation is defined. In this relation x is the variable that defines all inputs of the relation and y is the variable that defines all outputs of the relation. In the ordered pairs, the set of x-coordinates is called domain of the relation.

Remember, these are quadrilaterals, so they must add up to 360°. Just add up the angles and then do 360 minus that number to solve for x.
Therefore:
1. 118 + 90 + 99 = 307
360 - 307 = 53
2. 110 + 96 + 78 = 284
360 - 284 = 76
3. 48 + 118 + 97 = 263
360 - 263 = 97
4. 105 + 99 + 64 = 268
360 - 268 = 92
5. 103 + 63 + 113 = 279
360 - 279 = 81
6. 95 + 80 + 88 = 263
360 - 263 = 97
Answer:
h= 0.25c +4
Step-by-step explanation:
➀ Define variables
Assuming that you are asking for the equation representing the height of the stack, let's start by letting the height of the stack be h inches and the number of cups be c.
➁ Find the increase in height with every additional cup
If an additional cup is stacked on the first cup, the height increment is 0.25 inches. When 2 cups are added, the height increment is 2(0.25)= 0.5 inches. Thus the expression for the increase in height is 0.25c, where c is the number of cups as we have already defined in step 1.
➂ Find the total height of the stack
Since the height of the first cup remains constant at 4 inches tall, the total height of the stack can be represented by the equation:
h= 0.25c +4
The second equation equals: 3X +18y=60 (Both sides times 3)
And then use this new equation minus the first equation, you will get:
Left side: (3X +18y) - (<span>3x+6y)
Right side: 60-30
So 12y=30
Then y=2.5
Take y value into one of the three equations, you will get x=5
or
in another easier way:
Directly minus the second equation from the first one:
</span>(3x+6y) -(<span>X+6y)=10
</span>2X = 10
X = 5
Get Y is easy, Y=2.5
