Answer:
The answer to your question is the letter B) y = 3x - 3
Step-by-step explanation:
Data
Point = (2, 3)
slope = m = 3
Process
To solve this problem just substitute the values given in the slope-point equation.
Formula
y - y1 = m(x - x1)
x1 = 2 y1 = 3
-Substitution
y - 3 = 3(x - 2)
-Expand
y - 3 = 3x - 6
-Solve for y
y = 3x - 6 + 3
-Result
y = 3x - 3
Answer:
60 feet
Step-by-step explanation:
The height, h (in meters), of the object launched from a platform is represented by the equation
where x is the time (in seconds) passed after the launch.
The time of launch is 
(0 seconds passed after the launch)
Substitute to find the height:
Answer:
Kenjii can use 13.19 kilowatt-hour.
Step-by-step explanation:
Giving the following information:
Kenji's electricity bill costs $21.56 per month plus $2.46 per kilowatt-hour.
<u>First, we will structure the total cost formula:</u>
Total cost= 21.56 + 2.46*x
x= kilowatt-hour
54= 21.56 + 2.46x
32.44= 2.46x
13.19= x
Kenjii can use 13.19 kilowatt-hour.
(r, theta)= (8, 3/2 pi)
r=(x^2 +y^2)^(1/2)
theta= 3/2 pi
x= r(costheta)
y=r(sintheta)
x=8(cos(3/2 pi))
y=8(sin(3/2 pi))
x=8(0)
y=8(-1)
x=0
y=-8
r=((-8)^2+(0)^2)^(1/2)
r=(64+0)^(1/2)
r=8
rectangular coordinates= (0,-8)
