How do we find the x-intercept of 3x + 2y = 6? Set y = 0 and solve the resulting equation for x:
3x + 0 = 6, or x = 2. The x-intercept is then (0, 2).
y-intercept? Do the same thing, except set x = 0 and solve for y:
3(0) + 2y = 6, or y = 3. The y-int is then (0,3).
You will see problems of this type over and over in algebra, so it'd be best that you learn how to do them now.
Answer: The boy would be chosen
Step-by-step explanation:
the fraction for the probability for girls is 3/10
the fraction for the probability for boys is 7/10
Answer:
(5.33 + 2h) ≥ 7
h ≥ 0.835
Step-by-step explanation:
Let in the last two days Julian has to practice the drum for h hours each.
Then in two days, he has to practice 2h hours,
He has already practiced hours before those last two days.
Therefore, he has practiced this week by (5.33 + 2h) hours.
Now, given that Julian needs to spend at least 7 hours each week practicing the drums.
Hence, we can write the inequality
(5.33 + 2h) ≥ 7
⇒ 2h ≥ 1.67
⇒ h ≥ 0.835 hours
Therefore, Julian has to practice for 0.835 hours for the last two days of the week. (Answer)
