Use the foil method to multiply out the expressions. Then solve for x by first combining like terms and then using inverse properties
Answer: 7 7/8 hours long
Step-by-step explanation:
April worked 1 1/2 times as long as Carl did. 1 1/2 can be rewritten as 3/2. Number of Hours April worked on math project 3/2 times the Number of Hours Carl worked on Math project. Which Carl worked 5 1/4 hours long, which can be rewritten as 21/4
Answer: Choice C
The vertical asymptote at x = -4 tells us that -4 is not part of the domain. This only applies to 1/(x+4). If we plug in x = -4, we get...
f(x) = 1/(x+4)
f(-4) = 1/(-4+4)
f(-4) = 1/0
f(-4) = undefined; because of the division by zero error
The value x = -4 is allowed in the other answer choices.
4 1/2 + 3 3/4 = 4 2/4 + 3 3/4 = 7 5/4 = 8 1/4...what he needs for A and B
He used 12 inches of cable...
12 - 8 1/4 = 11 4/4 - 8 1/4 = 3 3/4....length left after A and B are made
he doesn't have enough to make the last one...
5 1/8 - 3 3/4 = 41/8 - 15/4 = 41/8 - 30/8 = 11/8 = 1 3/8....he is short by 1 3/8 inches
Answer:
Step-by-step explanation:
What are the center and radius of the circle described by the equation x2 + y2 + 6x + 10y + 18 = 0?
Center (3.5); Radius 4
Center (-3,-5); Radius 4
O Center (3,5); Radius 16
O Center (3.5); Radius 10
x² + y²+ 6x + 10y + 18 = 0
x² + 6x + y² + 10y = -18
x² + 6x + 9 + y² + 10y + 25 = -18 + 6 + 9
x² + 3x + 3x + 9 + y² + 5y + 5y + 25 = -3
