you need to find to find the value of x and y.
2x>(-15-5y)
x>(-15-5y)/2
now put this in to other equation and solve for y and then put the y value in and find x.
Answer:
miles [or, 9.2 miles]
Step-by-step explanation:
<u>Complete Question:</u>
Christine runs 10 miles in 75 minutes. At the same rate, how many miles would she ru
n in 69 minutes?
<u>Solution:</u>
We need to find the unit rate first and then find our answer. To get unit rate, we need to know the number of miles she runs in "1 minute". So, we will divide number of miles by number of minutes, that is given. Hence:

That means in 1 minute, Christine runs 2/15th of a mile.
Now, we want to know how many miles she will run in 69 minutes. We simply multiply unit rate (2/15) by the number of minutes (which is 69). Thus we have:

In decimal, doing division, that is 9.2 miles
Lower case numbers for points
If they have a different slope they are intersecting lines. If they have the same slope and the same y-intercept they are coinciding lines...
y=4x, m=4, b=0
3x+2y=10
2y=-3x+10
y=-1.5x+5, m=-1.5, b=5
Since this has a different slope they are intersecting lines...
Answer:
D. 38.8 feet.
Step-by-step explanation:
Let the height of the apple be x + 5.5 feet.
Then tan 48 = x / 30
x = 30 tan 48
x = 33.3 feet.
So the height of the apple = 33.3 + 5.5
= 38.8 feet.
