Answer:One way of knowing the correct answers, we substitute the ordered pairs to the function and see whether it would make the function true.
3x – 4y = 21
A. (−3, 3)
3(-3) – 4(3) = 21
-21 = 21 ---------------> not equal
B. (−1, −6)
3(-1) – 4(-6) = 21
21 = 21 ---------------> equal
C. (7, 0)
3(7) – 4(0) = 21
21 = 21 ---------------> equal
D. (11, 3)
3(11) – 4(3) = 21
21 = 21 ---------------> equal
Answer:
5n
Step-by-step explanation:
The sequence is a list of multiples of 5, starting with 5×1. The n-th multiple is 5n.
Once you detect that there is a delay or disability, then you should continue to be the reliable partner in child care to the family so this is True.
<h3>What should be done when a delay in child development is seen?</h3>
The observation and screening process can lead to a child care partner discovering a delay or disability.
When this happens, you should report to your supervisor to check if the child is eligible for federal and state programs related to their condition. Whatever the case, you should remain accessible to the family as their partner in child care.

Answer:
Option A - Neither. Lines intersect but are not perpendicular. One Solution.
Option B - Lines are equivalent. Infinitely many solutions
Option C - Lines are perpendicular. Only one solution
Option D - Lines are parallel. No solution
Step-by-step explanation:
The slope equation is known as;
y = mx + c
Where m is slope and c is intercept.
Now, two lines are parallel if their slopes are equal.
Looking at the options;
Option D with y = 12x + 6 and y = 12x - 7 have the same slope of 12.
Thus,the lines are parrallel, no solution.
Two lines are perpendicular if the product of their slopes is -1. Option C is the one that falls into this category because -2/5 × 5/2 = - 1. Thus, lines here are perpendicular and have one solution.
Two lines are said to intersect but not perpendicular if they have different slopes but their products are not -1.
Option A falls into this category because - 9 ≠ 3/2 and their product is not -1.
Two lines are said to be equivalent with infinitely many solutions when their slopes and y-intercept are equal.
Option B falls into this category.
