Answer: 720 because 3*3=9 and 240*3=720
Step-by-step explanation:
What are all of the x-intercepts of the continuous function in the table? (0, 8) (–4, 0) (–4, 0), (4, 0) (–4, 0), (0, 8), (4, 0)
Shkiper50 [21]
In a polynomial function or data such as that which are given in the table in this item, the value of the x-intercepts are those which corresponds to the value of y being zero. From the data, the answer to this item would be,
(-4,0) and (4,0)
Answer: 3 hours
Step-by-step explanation: Subtract the flat fee first. 15-3=12. She earned $12 without the flat fee, so divide that by 4. $12/$4 per hour = 3 hours.
Answer:
This is a really simple example, but imagine you had two marbles in a bowl. One is blue and one is green. Without looking, you reach into the bowl and pick one marble. What is the probability that the marble is blue?
There are two total marbles and you pick one, with one being blue and one being green. The probability that you pick the blue marble instead of the green marble is 1/2. The 2 represents the total number of marbles and the 1 represents the favorable outcome of drawing a blue marble.
Hope this helps!
<em><u>Answer:</u></em>
(x − 4)² −4
<em><u>Step-by-step explanation:</u></em>
Use the form ax² + bx + c, to find the values of a, b, and c.
a = 1 , b = − 8 , c = 12
Consider the vertex form of a parabola.
a (x + d)² 2 + e
Find the value of d using the formula d = b/2a.
Reduce the expression by cancelling the common factors.
Factor 2 out of 8.
d = − 2⋅4/2⋅1
Cancel the common factors.
Factor 2 out of 2⋅1.
d = − 2⋅4/2(1)
Cancel the common factor.
Cancel '
d = − '2'⋅4/'2'⋅1
Rewrite the expression.
d = − 4/1
Divide 4 by 1.
d = − 1⋅4
Multiply −1 by 4.
d = −4
Find the value of e using the formula
e = c − b2²/4a.
Simplify each term.
Multiply 4 by 1.
e = 12 − (−8)²/4⋅1
Raise −8 to the power of 2.
e = 12 − 64/4⋅1
Multiply 4 by 1.
e = 12 − 64/4
Divide 64 by 4.
e = 12 − 1⋅16
Multiply −1 by 16.
e = 12 − 16
Subtract 16 from 12.
e = −4
Substitute the values of a, d, and e into the vertex form a(x + d)² + e.
(x − 4)² −4
