Hi! We’re going to use the pythagorean theorem to answer this.

3 + x^2 = 8
subtract 3 from 8
x^2=5
take the square root of both sides
x=sqrt5

Simplify ( 1/2A + 1/2B )^2
zysi [14]
Notice that both A and B are multiplied by (1/2).

Thus, the given expression can be re-written as [(1/2)(A+B)]^2.

Square the (1/2) and the (A+B) separately, and then multiply together the resulting squares:

(1/4)(A^2 + 2AB + B^2)

Can someone plz explain how to do this
swat32

Answer:

-2

Step-by-step explanation:

First, you need to find the equation.

f(x) = -3x + b

Now we need to find the y-intercept.

f(x) = -3x + b

f(-9) = -3(1) + b

-9 = -3 + b

-6 = b

f(x) = -3x - 6

The zero of f means that f(x) = 0

f(0) = -3x - 6

f(6) = -3x

x = -2
