At most 4 times
hmm
where it touches is when y=0
so just have lots of zeroes
y=(x-r1) is a zero
so 4 zeroes is
y=(x-r1)(x-r2)(x-r3)(x-r4)
if we expand it it is degree 4
minimum degree is 4th
Tuff I don’t understand it but for question four the answer is
Answer:
(-7, -8)
Step-by-step explanation:
To start we have to isolate a variable to get an equation for it.
Let's get an equation for x from the first equation:
x - 2y = 9
x = 2y + 9
Now that we know what x is in terms of y, lets plug it into our second equation:
3(2y + 9) - 5y = 19
6y + 27 - 5y = 19
y + 27 = 19
y = -8
Now that we know what y equals, let's plug it into our first equation and solve for x:
x - 2(-8) = 9
x + 16 = 9
x = -7
Now that we have x and y, we make our ordered pair, in terms of (x, y):
(-7, -8)
Hope this helps!

Answer:
2
Step-by-step explanation:
3x+15=21 (the opposite side of parallelogram is equal)
3x=21-15
3x=6
x=6/3
so x=2
AD=2
