X-intercepts
f(x) = 0

4x² - 15x - 4 = 0

4x² - 16x + x - 4 = 0

4x(x - 4) + 1(x - 4) = 0

(x - 4)(4x + 1) = 0 ⇔ x - 4 = 0 or 4x + 1 = 0

x = 4 or 4x = - 1 ⇒ x = - 1/4

Answer: -1/4 and 4.

Jan has $130. If she saves $25 per week, in how many weeks will she have $600?

serious [3.7K]

Let's represent the number of weeks with the variable 'w':

130 + 25w = 600

We subtract both sides by 130:

25w = 470

w = 18.8

We round up:

It will take her 19 weeks.

Nicole deposited $2,000 at 6% simple interest. How long will it be before she has $2,600 in her account?

Kryger [21]

FV=PV(1+r)ⁿ

FV=Future Value, or the $2,600 that you want.
PV=Present Value, or the value that you are depositing.
APR: .06

2,600=2,000(1.06)ⁿ
2,600=2120ⁿ
It would take about a year for Nicole to get $2600.

~Hope I helped~
