Answer:
Step-by-step explanation:
y=-1
because when y = - 1,
it is an equation of x axis.. hence it will parallel to x axis....
Since two people take both courses, we can subtract two from 7, 8, and 21, giving us 5, 6, and 19.
Add 5 and 6 together to get 11. Since eleven students are in those two groups, we can answer this. The answer will be 11/19.
<span>It mainly means 'simplifying an expression down to a single numerical value', I believe.</span>
-120 + 13m, at time m = 6, would be -120 + 78, or -42 feet.
REMEMBER: A rotation of 180 degrees means you flip both x and y numbers
E(-4,3)
F(7,-5)
G(-2,-8)
