Y^2 + y - 6 = 0

A way we could solve this equation is by factoring.

To factor, we have to find two factors of -6 that add up to 1, which is the coefficient for y.

-2 and 3 are two factors of -6 that add to 1.

Now, since we have 2 factors, let's factor

(y - 2) (y + 3) = 0

In order for this to be true, y-2 OR y+3 must equal 0.

y - 2 = 0

Add both sides by 2

y = 2

Now, let's solve for y+3 = 0

y + 3 = 0

Subtract both sides by 3

y = -3

The two solutions to this equation are y=2 and y= -3.

Have an awesome day! :)

5. The Jones family orders four pizzas to eat. Each pizza is sliced into four parts. How many pizza slices do they get in total?

morpeh [17]

Answer:

16 slices

Step-by-step explanation:

Given :

Number of pizzas ordered = 4

Number of slices per pizza = 4

If 4 pizzas are each sliced into 4 parts ; the we have :

Pizza 1 = 4 slices

Pizza 2 = 4 slices

Pizza 3 = 4 slices

Pizza 4 = 4 slices

Total slices = (4 +4 +4 +4) = 16 slices

Without graphing, determine the range of the runction f(x)=4|x+6|-5

Since is a positive a value (4) we know that the graph opens upward. -5 represents how far up or down the “vertex” is of the absolute value graph. This means that the range is -5
