This is most likely a rectangular prism, C.
(3,-5)(-8,4)
slope(m) = (4 - (-5) / (-8-3) = (4 + 5) / -11 = -9/11
point slope form : y - y1 = m(x - x1)
there will be 2 answers because there is 2 sets of points
using (3,-5)
y - (-5) = -9/11(x - 3) =
y + 5 = - 9/11(x - 3) <=== here is one
using (-8,4)
y - 4 = -9/11(x - (-8) =
y - 4 = -9/11(x + 8) <== here is the other one
Answer:
So, how do we check to see if two functions are inverses of each other? Well, we learned before that we can look at the graphs.
Step-by-step explanation:
Remember, if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions.
Car A Car B
d=rt d = rt
d = ra * 2.4 d = rb 4
ra = rb+22
distances are the same so set the equations equal
ra * 2.4 =rb *4
substitue in for ra
(rb+22) 2.4 =rb *4
distribute
2.4 rb +52.8 = 4 rb
subtract 2.4 rb from each side
52.8 = 1.6 rb
33 = rb
Car b travels at 33 miles per hour
Car a = 33+22
Car a = 55 miles per hour
Answer:
95.99
Step-by-step explanation:
8.97 / 44.86
.19995 --> 19.995 % discount
119.99 x .19995 = 23.9926 off of price
119.99 - 23.9926 = $95.99
