Answer:
(x, y) = (3, 7)
Step-by-step explanation:
If you divide the second equation by 2, it becomes ...
-x +2y = 11
Adding this to the first equation gives you the value of y:
(x -y) +(-x +2y) = (-4) +(11)
y = 7 . . . . . . . . simplify
The first equation can be rearranged to give an expression for x:
x = y -4
x = 7 -4 = 3
Then the solution is seen to be (x, y) = (3, 7).

Amelia was showing off her basketball skills. She scored a total of 14 shots for a total of 32 points. How many 2 point and 3 point shots did she make?
Answer:
Step-by-step explanation:
x+y=14
y=14-x
2x+3y=32, using y=14-x we have
2x+3(14-x)=32
2x+42-3x=32
-x+42=32
-x=-10
x=10, and since y=14-x
y=14-10=4
So Amelia made 10 two-pointers and 4 three-pointers.

What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
ΔABD is similar to ΔBCD.
This means,
The corresponding sides ratio is equal.
AB/BC = BD/CD = AD/BD
AB/m = BD/7 = 11/BD
Now,
BD/7 = 11/BD
BD² = 77
BD = √77
Now,
ΔBDC
BC² = CD² + BD²
m² = 7² + 77
m² = 49 + 77
m² = 126
m = √126
Thus,
The value of m in the figure is √126.
