Answer:
y = 2 ± 
Step-by-step explanation:
Solve using separable equations
First put x and dx on the same side and do the same for y
(y-2)dy = (x-2)dx
Now you can integrate
+ C1
Now we depending on how what ur instructor wants you may need to give exact solutions. We can do this by solving he quadratic equation for Y
Doing this you get:
y = 2 ±
<em>Note C's were simplified.</em>
Answer:
5/17
Step-by-step explanation:
This is a question to calculate probability from odds. The formula is given as:
A formula for calculating probability from odds is P = Odds / (Odds + 1)
From the question , we are told that the odds of receiving a gift is
= 5:12
The probability of Jessica receiving a gift =
Probability = Odds / (Odds + 1)
P = 5/12 / ( 5/12 + 1)
P = (5/12)/ (17/12)
P = 5/12 × 12/17
= 5/17
Therefore, the probability of Jessica. receiving a gift is 5/17.
Answer:
(4, -2)

Answer:
56
Step-by-step explanation:
Givens
Given Ratio = 2/5
Given mass on earth = 140
Ratio
2/5 = x/140 or
0.4 = x / 140
Solution
2/5 = x/140 Cross multiply
5x = 2*140 Combine
5x = 280 Divide by 5
x = 280/5
x = 56
You could also do this by combining the left side of the original proportion into 0.4
0.4 = x / 140 Multiply both sides by 140
0.4*140 = x Combine the left
56 = x
