<span>Just graph the function up to and/or including the points indicated.
- if you have a piecewise function defined as y=x when x < 0
y=-x when x >=1
You would graph y=x from the negative direction up to 0 (but leaving an open circle on 0 because the function is not defined there
Then start at point 1 (this time with a closed circle because y=-x is defined at 1, and graph y=-x.</span>
Answer:
False.
Step-by-step explanation:
A complementary angle is an angle where two seperate angles add together for a 90 degree angle. They usually share a side, but not always.
To solve this problem we can use system of equations.
First equation can be
321=x+y
where x - ppl between 4-17 and y - adult
second equation can be as follows
1590=6*y+4*x
So we have

From first equation we get value of x in times of y
x=321-y
Now we can substitute it into second eq.
1590=6y+4(321-y)
now simply if
1590=6y+1284-4y /-1284 both sides
306=2y /:2 divide both sides by 2
y=153
Now we can back substitude
x=321-153
x=168
So we get result
Answer: Correct answer is 1st option , 12.3
Step-by-step explanation:
We can find the value of x by calculating the tangent of the angle 39.
We know, that tangent of an angle in a triangle = Perpendicular/Base, corresponding to that angle.
So, tan 39 = 10/x
Again, we know that tan 39 = .81
So, .81 = 10/ x
or, x = 10/.81
or, x = 12.34
So value of x to the nearest tenth = 12.3
Hope thsi helps
