F(x) = x-5
X=8
Then plug in x as 8
8-5=3
Answer:
5/52
Step-by-step explanation:
There are 52 cards in a deck, with 26 red and 26 black cards. There are 2 red ones, 2 black threes, and 1 six of hearts. The # of favorable outcomes is 2 + 2 + 1 = 5, so the answer is 5/52.
Y = x + 8....the slope here is 1. A parallel line will have the same slope.
y = mx + b
slope(m) = 1
(2,16)....x = 2 and y = 16
now we sub into the formula and find b, the y int
16 = 1(2) + b
16 = 2 + b
16 - 2 = b
14 = b
so ur equation is : y = x + 14 <==
Answer:
x-intercept (s):
For this case h (x) = 0
x2 - 2x - 8 = 0
(x-4) * (x + 2) = 0
x1 = 4
x2 = -2
y-intercept:
For this case x = 0
h (0) = (0)2 - 2 (0) - 8
h (0) = - 8
vertex:
We derive the equation:
h '(x) = x2 - 2x - 8
h (x) = 2x - 2
We match zero:
2x-2 = 0
x = 2/2
x = 1
We evaluate the function for x = 1
h (1) = (1)2 - 2 (1) - 8
h (1) = 1 - 2 - 8
h (1) = -9
The vertex is:
(1, -9)
axis of symmetry of the function:
x = 1
