Natalia solved the problem below incorrectly. Find Natalia's mistake, explain what she should have done and tell me what the correct answer is.
x÷5 + 2 = 7

x÷5 + 2 + -2= 7 + 2

x÷5 = 9

x÷5x5 = 9x5

x = 45

y=mx+b

step-by-step explanation:

m slope

b y-intercept

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
