Sara has $150 in her savings account. The amount in her account increases by %6 every year. If she does not put more money into

strojnjashka [21]

Answer:

$159

Step-by-step explanation:

we know that

The equation of a exponential growth function is equal to

$y=a(1+r)^x$

where

y is the balance in the saving account

x is the number of years

a is the initial amount

r is the percent rate of change

we have

$a=\$150\\r=6\%=6/100=0.06$

substitute

$y=150(1+0.06)^x$

$y=150(1.06)^x$

For x= 1 year

substitute

$y=150(1.06)^1=\$159$

What is the slope-intercept form of 6x −2y−4 = 0?<br> Can you please explain with some details?

Morgarella [4.7K]

$6x -2y-4 = 0 \\ \\the \ slope \ intercept \ form \ is : \\ \\ y= mx +b \\ \\6x -2y-4 = 0 \\ \\-2y =-6x+4\ \ /:(-2)\\ \\y=\frac{-6}{-2}x+\frac{4}{(-2)}\\ \\y=3x-2 \\ \\ the \ slope \ (the multiplier \ of \ x \ represented \ by \ m ) \ is \3\\ \\ and \ the \ y-intercept \ (the constantrepresented \ by \ b \ ) \ is \ -2$
