What is -4+(-2)=

I have no clue what i’m doing

Final answer:

The two numbers that multiply to 24 and add to 2 are -4 and -6. You can find these through the process of elimination with the equations x*y=24 and x+y=2.

Explanation:

The two numbers that multiply to 24 and add to 2 are -4 and -6. Let's find out how:

1. First, you should write down the equation based on the question, x*y=24 (x and y are the two numbers).
2. Then, form another equation according to the question, x+y=2.
3. Now, solve these two equations. With some trial and error, you will find the two numbers are -4 and -6, because (-4)*(-6)=24 and -4+-6=2.

Note that the two numbers are negative which is why they add to a positive number when multiplied.

The graph that represents the following piecewise defined function is of f(x) = x; x <-2 , -2; -2 < or = to x < or = to 1, x-3; x> or = to 1 is the first graph (Image attached)

What is a piecewise function?

A piecewise function is known to be a function that has been formed from pieces of a lot of functions over a lot of intervals.

An example, we can say a piecewise function f(x) where f(x) = -7 when -7 < x ≤ -4, f(x) = 4 when -4 < x ≤ -1, and f(x) = -5 when -1 <x ≤ 7.

The option that best explain the piecewise defined function is the image attached.

Step-by-step explanation:

Just took the test and got a 100

Answer:

it is (12,60)

Step-by-step explanation:

12x2.50= 30.00

60x1.50= 90.00

30+90= 120
