A parabola is the locus of points equidistant from the focus and directrix. This means the distance from the green point is the same to the focus as it is to the directrix. The appropriate choice is ...
... B. 7
Answer:
Option B (1,10)
Step-by-step explanation:
we have

we know that
If a ordered pair is on the graph of f(x) then the ordered pair must satisfy the function f(x)
<u><em>Verify each case</em></u>
case A) (0,0)
For x=0

Compare the value of f(x) with the y-coordinate of the ordered pair

therefore
The ordered pair is not on the graph of f(x)
case B) (1,10)
For x=1
Compare the value of f(x) with the y-coordinate of the ordered pair

therefore
The ordered pair is on the graph of f(x)
case C) (0,10)
For x=0

Compare the value of f(x) with the y-coordinate of the ordered pair

therefore
The ordered pair is not on the graph of f(x)
case D) (10,1)
For x=10

Compare the value of f(x) with the y-coordinate of the ordered pair

therefore
The ordered pair is not on the graph of f(x)
Answer:
-3/5
Step-by-step explanation:
First represent this with numbers. Less means subtraction -, times means multiplication *, is means equals =.
And let's represent "a number" with x.
63 - 15x = 72
Solve for x. First subtract 63 from both sides.
-15x = 72-63
-15x = 9
x = -9/15 = <u>-3/5</u>
Answer:
-8 -6 -3 4
Step-by-step explanation:
In a number line, the numbers on the are lesser than the numbers on the right. In a number line with integers, numbers going to the right from the midline which is 0 is positive and increases as you move to the right. As you move to the left, the numbers are negative and decreases as you move further to the left.
Attached is a picture of how it would look on a number line.
Find 20% of 45.80
0.20 * 45.8 = 9.16
So they should leave $9.16 for the tip.
