The equation in y = mx+b form is y = -450x+2745
where,
x = number of hours that have passed by
y = distance to destination in miles
The y intercept is 2745 since this is the initial starting y value, aka the starting distance. Therefore b = 2745.
The slope is -450 or -450/1 since for each hour, the distance goes down by 450. You can think of it as
slope = (change in y)/(change in x)
slope = (change in distance)/(change in time)
slope = (-450 miles)/(1 hour)
slope = -450
Answer:
1/2
Step-by-step explanation:
AC=18 and A'C'=9
AB(x)=A'B'
18(x)=9
x=9/18
x=1/2
Answer:
y=4/9
Step-by-step explanation:
Substitute 2y into the x
2(2y)+5y=4
4y+5y=4
9y=4
y=4/9
There are a number of different problems that you could do that will give you an outcome of 9/10
For example, 1/2 and 2/5 add up to 9/10.
3/10 and 6/10 also add up to 9/10.
Find the sum of 7/10 and 1/5
Find the sum of 7/20 and 11/20
Find the sum of 1/2 and 3/10 and 1/10
Find the sum of 1/5 and 2/5 and 3/10
Hope this helps :)
Answer:
28
Step-by-step explanation:
P(red marbles) = 3/7
no. if red marbles = 12
12/x = 3/7
3x = 12 x 7
3x = 84
x = 28
the total number of marbles are 28.
hope it helps .
all the best
