Answer:
B.
Step-by-step explanation:
If you calculate the sum of both you get:
5x + 2x + 4y - 7y = 24 + 26
7x - 3y = 50, which is B

Answer:
isosceles obtuse triangle
Step-by-step explanation:
The attached graph shows a plot of the three lines.
The triangle is an isosceles obtuse triangle in the 2nd quadrant.
_____
It is convenient to let a graphing calculator plot these lines. If you're going to plot them by hand, it usually works best to choose values of the variables for the variable that has the largest coefficient (3 in two of the equations). That way, you're not trying to plot coordinates that contain fractions.
15 over 7 × 11 over 3
165 over 21
7 and 6 over 7
Now your answer would be 7 over 6 over 7
How we got "15 over 7 " and "11 over 3"
1. 2(7) = 14 + 1 = 15 (which is equal to 15 over 7)
2. 3(3)= 9 + 2 = 11 (which equals 11 over 3)
