1) isolate y

4x + 5y = 60
-4x -4x
_____________
5y = -4x + 60

2) make y so that is is alone with no numbers beside it

5y = -4x + 60
__________
5

y = -4/5x + 60

3) the slope is ALWAYS the number to the left of x, even if it's a fraction. It's it a decimal, convert to a fraction. The last number (in this case is 60) is where the slope crosses the y-axis on the coordinate plane.

The slope is -4/5x + 60

HELP ASAP PLEASE!!

Answer:

Step-by-step explanation:

According to the table, function g(x) reaches the max height of 33, approx.

The equation of motion is f(x) = -16x^2 + 42x + 12.  We need to determine the maximum of this function.  To do this, find the x-coordinate of the vertex, which is x = -b/(2a), or x = -42/(2*-16), or 1.31 sec.

Evaluating f(x) = -16x^2 + 42x + 12 at x = 1.31 sec, we get f(1.31) = 39.6.

So it appears that f(x) has a higher max than does g(x); the difference is approx. 39.6 - 33, or 6.6

Alex purchased a new car for $28000. The car depreciates 7.25% each year. what will the price be in 5 years?
dalvyx [7]
Use the depreciation formula.

\sf p(1-r)^n

Where 'p' is the principal value, 'r' is the rate it depreciates, and 'n' is the time. Just plug in what we know:

\sf 28000(1-0.0725)^5

Simplify by subtracting:

\sf 28000(0.9275)^5

Simplify the exponent:

\sf 28000(0.6864)

Multiply:

\sf\approx\boxed{\sf\$ 19219.20}
