Answer:
y=4x-4
Step-by-step explanation:
You know that a line perpendicular to the equation (y= -1/4x-14) would have an opposite reciprocal slope.
The slope from the given equation is -1/4x. Take the opposite reciprocal and you get 4/1x or 4x as your slope.
Now use the point-slope formula to find your b value.
(y-y1)=m(x-x1)
m= 4
Plug in (3,8) for x and y, and solve.
(y-8)= 4(x-3)
y-8= 4x -12
y=4x-4

A rocket is fired upward from ground level with an initial velocity of 1600ft/sec . When will the rocket be above 1000ft? Show your work. Round your answer to the nearest tenths. Write the answer in set notation.
Answers
Answer:
{t: 0.6 < t < 99.4}.
Step-by-step explanation:
Use one of the equations of motion under gravity.
s = ut + 0.5gt^2 where s = distance, u = initial velocity, g = acceleration due to gravity and t = the time.
So we have:
1000 = 1600t + 0.5* -32*t^2 ( acc due to gravity is negative as we are acting against it).
16t^2 - 1600t + 1000 = 0
t = (1660 +/- sqrt(1600^2 - 4*16*1000) / 32
This gives t = 0.629 , 99.371 seconds.
So the time is above 0.6 seconds (to the nearest tenth) and before 99.4 seconds.

is −4[3(x−7)] and 6(14−2x) equiviant
Answers
Answer:
Yes.
Step-by-step explanation:
Set the equations equal to each other to determine their equality.
-4[3(x - 7)] = 6(14 - 2x)
Distribute the 3 and the 6 into their respective parenthesis.
-4[3x - 21] = 84 - 12x
Distribute the -4 into the brackets.
-12x + 84
Rearrange the equations.
84 - 12x = 84 - 12x
Since the equations come out to be the same thing on both sides so that any value satisfies it, the equations are equivalent.

Jada and her friends want to go indoor skating on Saturday night. Jacaranda Skating Zone charges $40 for entry and $12 per hour to skate, while Wiles Skating Zone charges $10 for entry and $22 per hour to skate. At how many hours would it be the same cost at either skating zones?
Answers
At 3 hours both Jacaranda and Wiles would have the same cost
Let y represent the total charges by Jacaranda and x represent the number of hours. Hence:
y = 12x + 40
Let z represent the total charges by wiles and x represent the number of hours. Hence:
z = 22x + 10
Since they are to have the same cost, hence:
y = z
12x + 40 = 22x + 10
10x = 30
x = 3 hours
Therefore at 3 hours both Jacaranda and Wiles would have the same cost.

Answer:

Step-by-step explanation:
no slope means no X or M in y=mx+b
leaves you with y=b which is whatever y is in the cordinate (x,y)
in this case, 6
Answer:
y=6
Step-by-step explanation:
We can use point slope form
y-y1 = m(x-x1)
where m is the slope and (x1,y1) is a point on the line
y-6 = 0(x-0)
y-6 = 0
Add 6 to each side
y-6+6 = 0+6
y=6
