Answer:

(d) see attached

Step-by-step explanation:

All of the answer choices show shading above a dashed line, so we need to look a little closer at the equation of the boundary line. Written as an equation, it is ...

3x +y = 9

When you set each variable to zero and solve for the other, you find the intercepts to be ...

y = 0, x-intercept: 3x = 9 ⇒ x = 3

x = 0, y-intercept: y = 9

The only graph that has x- and y-intercepts matching these values is the one attached.

It should be 95,040. On the first day, you have 12 choices. On the second, eleven, and so on, until day 5. 12x11x10x9x8.

does the following system of equations have a solution if so find it. 2x+y+z= 4 x-y+3z= -2 -x+y+z= -2

I'd suggest using "elimination by addition and subtraction" here, altho' there are other approaches (such as matrices, substitution, etc.).

Note that if you add the 3rd equation to the second, the x terms cancel out, and you are left with the system

- y + 3z = -2
y + z = -2
-----------------
4z = -4, so z = -1.

Next, multiply the 3rd equation by 2: You'll get -2x + 2y + 2z = -2.

Add this result to the first equation. The 2x terms will cancel, leaving you with the system

2y + 2z = -2
y + z = 4

This would be a good time to subst. -1 for z. We then get:

-2y - 2 = -2. Then y must be 0. y = 0.

Now subst. -1 for z and 0 for y in any of the original equations.

For example, x - (-1) + 3(0) = -2, so x + 1 = -2, or x = -3.

Then a tentative solution is (-3, -1, 0).

It's very important that you ensure that this satisfies all 3 of the originale quations.
