Sarah had a balance of $155 in her bank account at the start of the week. she withdrew $65.50 on monday, $23.25 on wednesday, and $26.45 on thursday. on friday she deposits $ 165.30.
a) write an expression to represent sarah's spending.
b) simplify your expression using pemdas. how much is in sarah's account at the end of the week?
c) find the difference between sarah's bank account balance at the start of the week and her current balance.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

d

step-by-step explanation:

i used the pitagoras theoreme

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
