Answer:
b
Step-by-step explanation:
Step-by-step explanation:
N = 4
Putting value of n
-66 = - 9(4) + 16 +4
-66 = - 36 + 20
-66 = - 16
= - 16 + 66
= 50
N = 10
Putting value of n
-66 = - 9(10) + 16 +4
-66 = - 90 + 20
-66 = - 70
= - 66 + 70
= 4

we first add 7+8=15 then 15×2=30 30+6=36 36×2=108
-3x+5y=-4
5y=3x-4
Y=3/5x-4/5
When it parallel to the line y=3/5x-4/5
It can be y=-3/5x+b
-5=6/5+b
B=-5-6/5=-25/5-6/5=-31/5
Y=-3/5x-31/5
3/5x+y=-31/5
Multiply 5
3x+5y=-31
<span>4−(2x+4)=5
4 - 2x - 4 = 5
-2x = 5
x = -5/2
x = - 2.5</span>
