Let x be taco salads, and y be drinks.
The equations are as follows:
1) 2x+2y=11
2) x+y=6.50
Use 2) to isolate for a variable, for example:
3) y=6.50-x
Using 3), substitute it back into 1) to solve for x.
2x+2(6.50-x)=11
2x-2x+13=11
The x's cancel out, leaving you with:
13=11
This is not true, and therefore you cannot determine the prices of the taco salads or iced tea.
Answer:
The range is {1,3,4,7}
Step-by-step explanation:
The range is the output
f = {(2,3), (5, 7), (3, 3), (5, 4), (9, 1))
The range is {3,7,3,4,1}
We normally list the numbers in order from smallest to largest and do not list duplicates
The range is {1,3,4,7}
Triangle, not a triangle, not a triangle, triangle
Determining if three side lengths can make a triangle is easier than it looks. All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.[
Since the lines are parallel and you know the slope of
is -2, you know the slope of line
will also be -2. You can see on the coordinate grid that line
crosses the y-axis at -1. When you piece all of these facts together into slope-intercept form you get
= -2x - 1.
