Answer:
x = -34, y = -17
Step-by-step explanation:
7x+4=88
7x=84
x=12
7x-12=7*(12)-2=82
angle 1=180-82=98
Answer:
The answer is B.
Step-by-step explanation:
The tank initially had 1,200 gallons of water, which is leaking at the rate of 2.5 gallons per hour.
To get the speed of growth of plant we proceed as follows;
rate=(distance)/(time taken)
distance( length) of growth of the plant in 14 days is 3.6 m.
1 day=86400 sec
14 days=86400x14=1,209,600 sec
1 m=1000000 micrometer
3.6 m=3600000 micrometer
thus the rate of growth will be:
3600000/1209600
=2.9762 micrometers per second
The right answer is the 2nd one.
It's using the quadratic equation
