Week 9- Math10

This week in math ten we started our new unit on relations. I will be demonstrating how to find the x-intercept

for example

3^x+5^y=20

when finding the x intercept y will always equal 0

so you would multiply the 5 by 0 which would give you

3^x=20

from there you would isolate the x,

to isolate the x divide x by 3 and the 20 by which would give you

\frac{3^x} {3} =\frac {20}{3} 

which would give you

(6.667,0) rounded
