Answer:

The y intercept is 5

Step-by-step explanation:

The slope intercept form of an equation is

y = mx+b where m is the slope and b is the y intercept

y = -3/2x+b

Substitute the point into the equation and solve for b

8 = -3/2(-2)+b

8 = 3+b

8-3 =b

5=b

The y intercept is 5

What's the property to (x/y)^3=x^3/y^3

Sphinxa [80]

Answer:

Power of a quotient property

Step-by-step explanation:

It is power of a quotient property, when you have different bases, whose quotient(division) is raised to the same power, it is equal to dividing, each base raised to same power.

Here, x and y are different bases and 3 is the common power to both of them.

In general for any power, say m :

$(\frac{x}{y} )^{m} = \frac{x^{m} }{y^{m}}$

Because, $(\frac{x}{y} )^{m} = \frac{x}{y} \times \frac{x}{y} \times\frac{x}{y}.... m times$

And, $(\frac{x}{y} )^{3} = \frac{x}{y} \times \frac{x}{y} \times\frac{x}{y}$

i.e $(\frac{x}{y} )^{3} = \frac{x^{3} }{y^{3}}$

Perform indicated operations for function: f(x)=x^2+1 use in f(x+h)-f(x)/h

8090 [49]

For $f(x+h) - \dfrac{f(x)}{h}$ reading the fraction like f(x)/h only (f(x+h) start fraction f(x) / h end fraction), the answer is $-x^2/y + x^2 + 2x + y + y^2 - 1/y + 1$
