Hundreds 100
tens 20
ones 18
so add 100+20+18 and get
138 is your answer
Hope this helped! :D
Answer:
#6
Domain = {6, 8, 9, 11}
This represents the ages of the students surveyed.
Range = {0, 1, 2, 3}
The range is the possible number of pets that the students may have.
This is not a function because in functions, each x-value can only have one y-value. The x-value, age 11, has two possible y-values, number of pets.
#7
Domain = {1, 2, 3, 4, 5}
This represents the time passed in hours that the distance was measured
Range = {50, 100, 150, 200}
This represents the possible distances in miles that were measured.
This is a function. Each x-value only have one y-value. Each hour only has one possible distance.
Explanation:
The domain is used to state all of the possible x-values in a set of data.
The range is used to state all of the possible y-values in a set of data.
The x-values may also be called independent variables, and the y-values may be called dependent variables. The y-values change depending on what "x" is.
A set of data is a function when each and every x-value only has one y-value.
It is still a function if y-values have more than one x-value. (On a graph, it look like a horizontal line, like in question 7).
Answer:
12 feet
Step-by-step explanation:
Use the Pythagorean Theorem to find how high up the tree the top of the ladder reaches.
13 feet - hypotenuse
5 feet - can be a or b
a² + b² = c²
5² + b² = 13²
25 + b² = 169
b² = 144
b = √144
b = 12
The top of the ladder reaches 12 feet up the tree.
Hope that helps.
We can use the FOIL method to solve.
(5x + 3)(7x - 7)
(5x * 7x) + (5x * -7) + (3 * 7x) + (3 * -7)
35x - 35x + 21x - 21
0 + 0
0
Best of Luck!
I would recommend MathPapa or Cymath for this, if you’d like to know the steps in solving this.
I believe the answer to this is no solution, though.
