Answer:
3n - 5
Step-by-step explanation:
f(n) = 3n - 5. Works for all of them
#1
y= 5x-7
y= -2/3x+3
#2
y=4/5x (+0)
y= -5/4x(+0)
Answer:
15. d(1,3) e(4,4) g(1,-1) f(4,-2)
16. e(2,-1) f(4,-1) g(2,-3) h(4,-5)
Step-by-step explanation:
These are the coordinates to each point (x,y)
I hope this helps!!
-2x + 7y = 10 ⇒ -2x + 7y = 10
x - 3y = -3 ⇒ <u>-2x + 6y = 6 </u>
y = 4
-2x + 7(4) = 10
-2x + 28 = 10
<u> -28 -28</u>
<u>-2x</u> = <u>-18</u>
-2 -2
x = 9
(x, y) = (9, 4)
