Answer:
5760
Step-by-step explanation:
(2 * 10)^6 * 0.00009
First solve inside the parentheses
20^6 * 0.00009
Then solve powers
64'000'000 * 0.00009
Solve multiplications
5760
This answer might not be the one that is asked for, as the writing is kind of vague, but if you turn this inn with explanation you will not get it wrong
Y=7 is just a straight horizonal line that is perpendicular to the y axis at 7
and y=1/2x+6, is in y=mx+b form where m=slope and b=yintercept so
to find the intersection, yo just find when both sentances are correct so
y=7
subsitute that into y=1/2x+6
7=1/2x+6
subtract 6 from both sides
1=1/2x
multiply both sides by 2
2=x
so the point (2,7) is the intersection
