The correct answer is C) y + 5 = 2(x + 3)
In order to find this, simply take the point and the slope and plug into the base form of point-slope form.
y - y1 = m(x - x1)
Use the slope for m and the point for (x1, y1)
y + 5 = 2(x + 3)
Answer:
0.01167
Step-by-step explanation:
180 - 0.669 = 89.331
complementary angle = 89.331
cos(89.331) = 0.01167
Speed of truck= x
speed of train=x-30
A loaded moving truck is traveling 30 mph faster than a freight train. in the time it takes the train to travel 135 miles, the truck travels 225 miles. find the speed of the truck.
A loaded moving truck is traveling 30 mph faster than a freight train...
(x-30)=speed of train
the time it takes the train to travel 135 miles, the truck travels 225 miles...
135/(x-30)=225/x
the you multiply on both sides the x values and get...
135x=225x-6750
then you subtract 225x on both sides...
-90x=-6750
then you divide -90 on both sides...
x=75
the speed of the truck is 75mph

Answer:
It will take 5 months and that height will be 20cm.
Step-by-step explanation:
Let the height of the tree be h cm and the number of months be m.
<u>Maple</u><u> </u><u>tree</u>
Initial height= 10cm
Total height= 10cm +2(number of months)
h= 2m +10 -----(1)
<u>Oak</u><u> </u><u>tree</u>
Initial height= 15cm
Total height= 15cm +1(number of months)
h= m +15 -----(2)
When the height of the two trees are the same,
2m +10= m +15
Solve for m:
2m -m= 15 -10
m= 5
Substitute m=5 into either equation 1 or 2 to obtain the height.
When m=5,
h= 5 +15
h= 20
You take the amount of days and multiply by 50! so if the days are d, and cost is c then c=50d
hope this helps, can i have brainliest!
