y = - 4x +3 when slope is -4
NOTE: Parallel lines have same slope.
For the line passing through point (-5, -6) the slope (m) = -4
Equation of that line:
(y - y1) = m (x -x1)
(y --6) = -4(x --5)
(y + 6) = -4(x + 5)
y + 6 = -4x -20
y = -4x -20 -6
y = -4x - 26
Answer:
B or C or maybe A
Step-by-step explanation:
The 2 horsepower is equal to 1492 watts.
Given that horsepower and watts are units of measure of power and they are directly proportional such that 5 horsepower is equal to 3730 watts.
Horsepower is a unit of measurement of power, or speed at which work is done, usually related to the power of an engine or motor. power is calculated by multiplying force (in pounds) by speed (in feet per second).
Let H= horsepower, W=watt
As we are given horsepower is directly proportional.
So, the relation is W=kH where k is constant.
Here, H=5 and W=3730.
By substituting the value of W and H we will find the value of k, we get
3730=k×5
3730/5=k
746=k
Now, substituting the value of k in relation and we get
W=746H
We have to find the power of 2 horsepower.
So, we will substitute H=2 in above relation, we get
W=746×2
W=1492 watts.
Hence, the 2 horsepower is equal to 1492 watts when 5 horsepower is equal to 3730 watts.

Answer: The system will succeed when the first alarm rings or when the first one fails, but the second one rings. The probability of this is 0.98
The probability of system failure is 1-(probability of success)= 1-0.98= 0.02
