Answer:
It would be 3.
Step-by-step explanation:
In order to get 3, notice how 4 became 2 for the small triangle. Well, in this case, 4/2=2. So, do 6/2=3.
It has infinitely solutions because x could be any number below or equal to -1
Answer:
s = 6
Step-by-step explanation:
1. Multiply the second line by 4: 4x+4y=16. They are the same line so there are infinitely many solutions.
2. Substitute for y.
x+(2x+10)=-2
3x+10=-2
3x=-12
x=-4
Plug x in
-4+y=-2
y=2
Final answer: (-4,2)
3. The answer is the first one because the solution is always where two lines intersect. The crossing of the x axis, y axis, and origin are irrelevant.
4. 2x+4=3x+1. This is because both equations define the value of y and therefore must be equivalent.
5. Infinitely many solutions. If you multiply the second equation by -3, you can tell it's coinciding or the same line.
1201.5 ft^2
the formula to find the area of a trapezoid is b1+b2/2xh
so plug in your numbers
16+11/2x89
therefore your answer is 1201.5 ft^2
