A student showed the steps below while solving the equation 14 = logs (2x-3) by graphing. Step 1:
Step 2:
Write a system of equations: Y1 = 14 y2 = logs(2x-3)
Use the change of base formula to rewrite the equations:
log(2x-3)
Y1 = log 14, y2 =
log5
Step 3:
Graph the two equations:

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

about the problem:

srry i'm not done ! i'll

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
