Answer:
B
Step-by-step explanation:
a function is a relation from a set of inputs (X) to a set of possible outputs where each input is related to exactly one output (Y). Only option B satisfies this definition
Answer:
- A. f(x) = (x - √2)(x + √3)
Step-by-step explanation:
Leading coefficient is 1, multiplicity is 1, roots are √2 and -√3. It means the function is the product of two binomials.
<u>The function with the roots of a and b is:</u>
<u>Substitute and and b:</u>
- f(x) = (x - √2)(x - (-√3)) ⇒
- f(x) = (x - √2)(x + √3)
Correct choice is A
Lets write down what we know...
Laura walks 3/5 mile to school everyday
Laura=3/5mile
Isaiah's walk is 3 times as long as Lauras, so
Isaiah=Laura*3
We know how far Lauras walk is so we can solve for Isaiah's walk
Isaiah=3/5*3 (or Isaiah=3/5+3/5+3/5 if thats easier for you to solve for)
Isaiah=9/5 miles
Now we know the answer! Great, Isaiah walks 9/5 miles to school each day. But 9/5 is an improper fraction, so lets convert it to a mixed number.
9/5=
To solve for this, we have to find out how many times 5 can go into 9. 5 goes into 9 one time with a remainder of 4, so we can write the mixed number as.
9/5= 1 4/5
Isaiah walks 9/5miles or 1 4/5 miles. Both are correct.
Answer:
x = 11
The value "11" makes the equation true.
2 ( x - 5 ) = 12
2 ( 11 - 5 ) = 12
2 ( 6 ) = 12
12 = 12
