I'm struggling fr now, pls can you help me answer these questions using the y= mx+ c method thanks!

Phoenix [80]

Answer:

Examination of the equation shows (graph):

x = 0, y = .5

Then .5 = c gives us the value of c giving

y = m x + .5 is our equation

Using y = 0, x = -1 gives

o = -1 * m + .5

m = .5

y = .5 x + .5 for the final equation

Check:

At x = 5, y = 3

3 = .5 (5) + .5 = 3

gavin deposited $1500 into his savings account that is compounded quarterly at an interest rate of 1.5%. How munch money will ga

creativ13 [48]

<u>Answer:</u>

The money will gavin have after 5 years is 1616.59$

<u>Explanation:</u>

We know that compound interest is given by

$A=P\left(1+\frac{r}{n}\right)^{n t}$

Where A = final amount

P = Principal amount = $1500 (given)

r = interest rate = 1.5% = 0.015

n = no. of times interest applied per time period = given quarterly = 4

t = time period = 5 years

So,

$A=1500\left(1+\frac{0.015}{4}\right)^{4 \times 5}$

$1500\left(1+\frac{0.015}{4}\right)^{20}$

= 1616.59$ which is the money will gavin have after 5 years
