Answer:
(1,0)
Step-by-step explanation:
reflection is flipping
flipping over Y would make -, to + or + to -
in this case -1,0 becomes 1,0

Answer:
no solution
Step-by-step explanation:
Hi there!
We are given this system of equations:
y=-2x+5
y=-2x+20
and we want to find the solution (the point in which the lines intersect)
There are 3 ways to solve a system, but let's use substitution in this case
Both equations are set to y, so they should be equal to each other via a property known as transitivity (if a=b and b=c, then a=c)
-2x+5=-2x+20 (the same as y=y)
Now let's solve for x
add 2x to both sides
5=20
In this case, we got an untrue statement. If this happens, then the lines won't intersect.
If they won't intersect, there's <u>no solution </u>
Hope this helps!
If b>a, b-a=5 so b=5+a
ab=126, using b from above
a(5+a)=126
5a+a^2=126
a^2+5a-126=0
(a+14)(a-9)=0, since a<0 the numbers are
-14 and -9
