Answer:
y=1/3x-3
Step-by-step explanation:
use the eqation y-y1 = m(x-x1)
plug in slop as m and points as x and y
so now you have --> y-(-4)=1/3(x-(-3))
two negatives = a positive --> y+4=1/3(x+3)
distribute the 1/3 --> y+4= 1/3x + 1
subtract 4 from both sides --> y= 1/3x - 3
100 and 101
the two integers are n and n+1. this means that 2n+1=201. n=100 and n+1=101
Answer:
4. C
5. 7
6. 3
Step-by-step explanation:
Four:
You have to multiply both of them. Just easy math!
Five:
This one is more complicated. You can see that it is asking you to plug in for a,
F(3):
F(1.25):
So now just subtract the answers. 7-0 equals 7.
Six:
Just look at the graph and see what number corresponds with y(6), or the 6 on the y axis. It appears to be three.
Have a nice day! Hope this helps. Don't forget to mark brainliest!
Answer:
speed of motorcycle = 40 mph
speed of car = 50 mph
Step-by-step explanation:
Here is the complete question
A car and a motorcycle leave at noon from the same location, heading in the same direction. The average speed of the car is 30 mph slower than twice the speed of the motorcycle. In two hours, the car is 20 miles ahead of the motorcycle. Find the speed of both the car and the motorcycle, in miles per hour.
Speed = distance / time
This question would be solved using simultaneous equation
let m = average speed of the motorcycle
c = average speed of the car
c = 2m - 30 equation 1
20 =(c - m) x 2 equation 2
insert equation 1 into equation 2 and divide through by 2
10 = (2m - 30) - m
solve for m
m = 40 mph
substitute for m in equation 1
2(40) - 20 = 50 mph
