The domain is the first number of any ordered pair--the x-coordinate.
For example, in the ordered pair (3,4), the domain is 3.
Answer:
either you have 62.6 + 62.5 + 55
or you have 55 + 55 + 70
Step-by-step explanation:
There are only two possible answers.
Either 55 degrees is by itself and the two equal angles are something other than 55 in which case you would write it as
x + x + 55 = 180 Subtract 55 from both sides
2x + 55 - 55 = 180 - 55
2x = 125 Divide by 2
x = 125/2
x = 62.5
OR
There are 2 angles that are both 55
x + 55 + 55 = 180
x + 110 = 180
x = 70
Answer:
=SUM(C2:C4, C7)
Step-by-step explanation:
In excel 'C' represent the cell ( intersection of row and column ),
Also, '=sum( )' represents the function of addition in the excel,
Also, when we operate all consecutive cells from
to ![Cm](https://tex.z-dn.net/?f=Cm)
Then under the function formula we write ![Cn:Cm](https://tex.z-dn.net/?f=Cn%3ACm)
And, when we operate a cell
with non consecutive cell ![Cl](https://tex.z-dn.net/?f=Cl)
Then under the function formula we write ![Cn, Cl](https://tex.z-dn.net/?f=Cn%2C%20Cl)
Hence, C2+C3+C4+C7 can be written as,
=SUM(C2:C4, C7)
Answer:
Option D. 1.29x + 1.35y ≤ 12
Step-by-step explanation:
Nick is making a fruit salad.
He buys apples per pound for = $1.29
He buys oranges per pound for = $1.35
He spend no more than $12.00 or we can say less than equal to $12
Let x represent the number of pounds of apples that Nick buys and y represent the number of pounds of oranges.
Cost of x pounds of apples = $1.29x
Cost of y pounds of oranges = $1.35y
Total cost = 1.29x + 1.35y
Total cost should be less than equal to $12.00
Therefore, inequality will be 1.29x + 1.35y ≤ 12
Option D. is the answer.
Answer:
x = 70
Step-by-step explanation:
Since the two sides are congruent, then the base angles are congruent.
2x + 40 = 180
subtract 40 from both sides
2x = 140
divide by 2 on both sides
x = 70
