7x -7/2 y = -49
7/2 y = 7x + 49
y = 2x + 14
y - intercept = 14
x - intercept : 2x + 14 = 0 so x = -7
answer is C.
x - intercept : -7
y - intercept : 14
Answer:
The answer is 3.5 mph
Step-by-step explanation:
30 x 2 = 60 minutes = 1 hour
1.75 x 2 = 3.5 miles
So 3.5 miles in 1 hour
3.5 mph
You don't define the ratio, so there are two answers:
If 2/3 is boys to girls, then,
2/3 = 24/x
x = 36 girls
If 2/3 is girls to boys, then,
2/3 = x/24
x = 16 girls
The last option: In his recursive formula, he should have the term an−1 instead of −4 to get an=an−1−3.
