If you plot the coordinates on a piece of graph paper your answer would come out too (1,-8)
Answer:
77
Step-by-step explanation:
Add all the numbers together (74+88+79+70+74) then divide by the amount of numbers there are (in this case 5) So (74+88+79+70+74=385) (385/5=77)
Combine the like terms
(4x^2 + 2x^2) +(7x - 5x) + (3 - 8)
6x^2 2x -5
6x^2 + 2x - 5
Answer is A
I believe this is Pythagorean theorem
The equation is
a^2+b^2+=c^2
In this case the equation would be
6^2+4^2=c^2
36+16=c^2
52=c^2
c=7.21110255093
