Answer:
2/3
Step-by-step explanation:
Gradient of line
= (y1-y2) /(x1-x2)
= (3-(-1))/(4-(-2))
= (3+1)/(4+2)
= 4/6
= 2/3
<span>(x ^1/8) (x^3/8) = x^4/8=x^1/2 = 12, x = 12^2 = 144
x=144
</span>
0.1458333333333333... you get the idea :)
For 15 you divide 6 by 12 which is two so she takes 2 quizzezs a week so 2 x 3 is 6 so the other three weeks she took 6 quizzes add 12 and 6 and you get 18 :)
