Answer:1) 2n - 1
2) 99
see in the picture, u can see that the number of shaded in figures 1 through n will form an evenly spaced sequence with:
u(1) = 1
u(2) = 3
u(3) = 5
u(4) = 7
u(5) = 9
......
=> The above sequence has: u1 = 1
d = 2
=> u(n) = 1 + 2(n - 1) = 2n - 1
=> the number of shaded squares in the n figure is 2n - 1
b) the number of shaded squares in the 50th figure is 2.50 - 1 = 99

Answer:
-7
Step-by-step explanation:
y-intercept
x=0
y-3= -2x-10
y=2(0)-10+3
y=0-7
y= -7
(0;-7)
Answer:
4x+3
How: -2x - (-6x) = 4
3 cannot be added there you go
