Y=mx+b
M is the slope
B is the y intercept
In this case 4 is the slope and -9 is the y intercept

What are the solutions to the equation x^2-8x=24

Oduvanchick [21]

$x^{2} - 8x = 24$

Transposing the equation to give zero on the RHS:
$x^{2} - 8x - 24 = 0$

Since we can't factorise it directly, we must complete the square to yield any solutions:
$x^{2} - 8x + ( \frac{8}{2})^2 - (\frac{8}{2})^2 - 24 = 0$
$(x^{2} - 8x + 16) - 16 - 24 = 0$
$(x-4)^2 - 40 = 0$
$(x-4)^2 = 40$
$x-4 = +/- \sqrt{40}$ ––> because square rooting yields a positive and negative solution.
x = 4 +/- $\sqrt{40}$
x = 4 +/- $2 \sqrt{10}$

Correct me if I'm wrong anyone.

3600 dollars is placed in an account with an annual interest rate of 5.5%. To the nearest year, how long will it take for the ac

Lynna [10]

Answer:

14.44

Step-by-step explanation:

The formula says

A=p(1+r)^t

A 7800

P 3600

R 0.055

T ?

7800=3600(1+0.055)^t

7800/3600=(1.055)^t

Log(7800/3600)= t × log(1.055)

T=log(7800/3600)/log(1.055)

T= 14.44 years
