Answer:
(11b^2 + 7) (11b^2 - 7)
Explanation:
Since both terms are perfect squares, factor using the difference of squares formula, a^2 - b^2 = (a + b) (a - b) where a = 121b^4 and b = 49
The equation
has it's solutions given by
. This is the quadratic formula.
Looking at your equation we see a=1; b=-3 and c=-6 so by the quadratic formula,
I'm sure you can work out what 9+24 is and so find the correct option :)
This problem mentions 'CHOICE,' which means you need to share the several possible answers that came with this problem.
There is an upfront charge of $12 per car. Next, each person in the car is charged $1. Supposing that x people are in the car, then the total cost, C(x), is
C(x) = $12 + ($1)x. This is a linear function whose domain could be, for example, [0,6], assuming that 6 people could fit into the car.
Answer:
Eric will catch up with Jan at 3 o-clock.
Idk I really tried sorry if its wrong lol
Y - y1 = m(x - x1)
slope(m) = -4/3
(0,-12)....x1 = 0 and y1 = -12
sub
y - (-12) = -4/3(x - 0) =
y + 12 = -4/3(x - 0) <=== point slope form
y + 12 = -4/3x
y = -4/3x - 12 <=== slope intercept form
y = -4/3x - 12
4/3x + y = -12
4x + 3y = -36 <=== standard form
