Answer:
∞
Step-by-step explanation:
In many instances, the term "amplitude" is used to refer to half the range. The range of any tangent function is (-∞, ∞), so its amplitude is ∞ regardless of any multiplier or offset.

Perhaps you're expected to say the absolute value of the coefficient of the trig function. In that case, the "amplitude" is 4/5.
Answer:
Step-by-step explanation:
1st on is one solution
2nd one is no solution (the lines have the same slope but different y- intercepts
3rd is infinitely many solutions (the equations are the same)
Answer: there are eight bicycles and 7 tricycles.
Step-by-step explanation:
Let x represent the number of bicycles that are there.
Let y represent the number of tricycles that are there.
There are a total of 15 bicycles and tricycles. This means that
x + y = 15
A bicycle has 2 wheels and a tricycle has 3 wheels. There are 37 wheels all together if we count them up. This means that
2x + 3y = 37- - - - - - - - - - - - - 1
Substituting x = 15 - y into equation 1, it becomes
2(15 - y) + 3y = 37
30 - 2y + 3y = 37
- 2y + 3y = 37 - 30
y = 7
x = 15 - y = 15 - 7
x = 8
Answer:
Start from coordinate 0, the exact center where the lines meet, then count down four, leave your point at -4 on the middle line.
