Answer:
Q1) y=-6/2+4. - Q2) y=2/4x-1
Step-by-step explanation:
In the first question y intercept was +4 in the graph
after rise/run we will go down 6 and 2 to the right so it will be -6/2 so its y=-6/2+4
In the second question y intercept was -1 then we go down 2 steps and we go to the left 4 times so it will be -2/-4 =2/4 so the answer y=2/4x-1
Answer:
Therefore, the probability is P=0.000064.
Step-by-step explanation:
We know that a pressure control apparatus contains 3 electronic tubes. The apparatus will not work unless all tubes are operative. If the probability of failure of each tube during some interval of time is 0.04.
We calculate the probability of failure of the apparatus.
We get:

Therefore, the probability is P=0.000064.
This question is asking us the unit rate, so we need to make a proportion.

When we solve it, we end up with:
4.5 = 2/3x
And now you substitute:

And you end up with your answer:
Blake burns 3/4 calories per minute.
Answer:
The answer is B and D
Step-by-step explanation:
First you need to find the common denominator. Think of a number that both 2 and 5 can go in to evenly. 10 is the best number, so, make both denominators 10. What you do to the bottom, you must do to the top.
Now your equation is 5/10-2/10
Your answer is 3/10
