12 + 3x = 30 // what is x?
3x = 18
x = 6
148.57-94 would equal 54.57
Answer:
17 square yards
Step-by-step explanation:
split it so you have a big rectangle and a small one. find the areas of both
the big one was 5(3)= 15, the second was 1(2)=2. add those together.
Answer:
answer B: (2,-2)
Step-by-step explanation:
First, write the equations on top of each other:

Then, multiply the the second equation by 2 so that we can use elimination of the y-variable:

Next, use elimination to find the value of "x":

So, your x-value is 2.
Now, substitute your x-value into one of your equations, let's take the second equation, 2x-y=6:

Your y-value is -2.
With all your information gathered, you find that the solution to this system of equation is (2,-2).
Answer:
-1
Step-by-step explanation:
You can do this two ways, the easiest way is to look at the graph.
What is g(4) means: When the x value equals 4, what does y equal?
Look for the coordinate with the x-value of 4 (it's asking for g(4). Now if you look at the y-value of the coordinate, it should tell you what g(4) is. So since the coordinate is (4,-1), g(4) is -1.
Another way to do it is to plug in 4 for x in the equation. So...
g(4) = -[f(4) - 3)]
g(4) = -[4 - 3]
g(4) = -[1]
g(4) = -1
