Answer:
The first one
Step-by-step explanation:
Because it already give you the y-intercept and you can solve x by doing 4 to 7 have to add 3 and x only have to add 1. It will give you a slope 3/1, so it is 3.
y=3x+1
Answer:
4 seconds to reach 200 feet
Step-by-step explanation:
You can use Desmos (graphing calculator) then plug in the equation and you will find the x-values are 7.188 and 0- the origin.
Divide 7.188 by 2 (this is also solving for the midpoint/axis of symmetry) and you get 3.594
Round 3.594 to the nearest second which would be 4 seconds.
Hope that helps and have a great day!
The answer is A just trust me
11.25
Convert 15% to decimal of 0.15
Then multiply 0.15 by 75 to get 11.25
Answer:
a) Rumble: $1
Pedal: $0.6
b) more than 5 songs
c) No, should be integers only
d) No, has to be integers greater than or equal to 2
Step-by-step explanation:
Part a
Rate per song is the slope.
Rumble:
Slope is 0.6
Rate is $0.6 per song
Pedal:
Slope: (4-2)/(2-0) = 1
Rate is $1 per song
Part b
Pedal would be a better deal if it's cost is lower than Rumble's
Rumble's cost: C = 2 + S
Pedal's cost: C = 4 + 0.6S
4 + 0.6S < 2 + S
0.4S > 2
S > 5
c) No, because no. of songs has to be positive integers only.
For example graph shows S = 2.5, but we know that's not possible
d) No, since the cost is 2 + S,
cost can't be in decimals either.
Cost too should be only integers greater than equal to 2
