Answer:
11.2 in
Step-by-step explanation:
The product of distances to the near and far intersection points with the circle is the same for any secants intersecting at a given external point. A tangent is the degenerate case where the near and far points of intersection are the same. This means ...
(9)(9) = (5)(5 + y)
81/5 = 5 + y
16.2 -5 = y = 11.2 . . . . inches
Answer:
(2,7)
Step-by-step explanation:
y=6x-5
y=x+5
Since they are both equal to y, set them equal to each other
6x-5 = x+5
Subtract x from each side
6x-x-5 = x+5-x
5x-5 = 5
Add 5 to each side
5x-5 +5 = 5+5
5x=10
Divide by 5
5x/5 = 10/5
x=2
y = x+5
y = 2+5
y =7
It would be 60% of the original price, of discount amount in 40%
Then, 40*60 / 100 = 2400/100 = 24
So, he bought the item @ $24
Answer:
3
Step-by-step explanation:
A polynomial is sometimes easier to evaluate if it is first written in Horner form:
-2x^2 -4x +3 = (-2x -4)x +3
For x = -2, this is ...
(-2(-2) -4)(-2) +3 = 0(-2) +3 = 3
The value is 3 when x = -2.
Answer:
b
c
Step-by-step explanation:
First question: x - 6 means there is a shift to the right.
Second Question: substitute the given values into the original equation for appropriate transformations.
Answer: 3 |x-4| + 2, because vertical stretch multiplies x, horizontal shifts are subtracted or added to x, and vertical shifts are added or subtracted to the entire function.
