We have (−1, 0) and (0,2) .....the slope is [ 2 − 0 ] / [ 0 − (−1) ] = 2 / 1 = 2
And the y intercept = 2
So......y = 2x + 2 is correct

Permute any 5 letters chosen from 7 = P (7,5) = 2520
lim sin(5x) / x multiply top/bottom by 5
x → 0
lim (5) sin(5x) / (5x) abd we can write
5 * lim sin(5x) / (5x)
5 * [ 1 ] =
5

I assume we have
The number of adult tickets sold (A) was 5 less than twice the number of children tickets (C).... they sold 95 adult tickets how many children tickets sold
A + 5 = 2C
95 + 5 = 2C
100 = 2C divide both sides by 2
50 = C = children's tickets sold
x = [ −b ± √ (b^2 − 4ac )] 2a a = 3 b = −7 c =−10
x = [ 7 ± √ (( −7)^2 − 4(3)(−10) ) ] / [ 2*3]
x = [ 7 ± √ [49 + 120] ] / 6
x = [ 7 ± √ 169 ] / 6
x = [7 ±13 ] / 6
x = 20/6 = 10/3 and x = −6/6 = −1
Note something else on 9(d), Max.....multipling top/ bottom by x, we have
[x^2 − 2x + 1 ] / [ x^2 − 1] =
[ ( x − 1 ) (x − 1) ] / [ (x + 1) ( x − 1) ] =
[x − 1 ] / [ x + 1]
