Pythagoras' Theorem
a^2+b^2=c^2
c is the longest side of the triangle
a and b are the other two sides
In a right angled triangle:
the square of the hypotenuse is equal to
the sum of the squares of the other two sides.
Answer:
Step-by-step explanation:
Given that 3 apples and 4 pears cost $1.95, 4 pears and 1 orange cost $1.60, and 1 orange and 3 apples cost $1.15, what is the cost of 1 apple?
Let us represent
Number of apples = x
Number of pears = y
Number of oranges = z
Given that
3 apples and 4 pears cost $1.95
3x + 4y = 1.95
4 pears and 1 orange cost $1.60
4y + z = 1.60
z = 1.60 - 4y
1 orange and 3 apples cost $1.15
z + 3x = 1.15
z = 1.15 - 3x
what is the cost of 1 apple?

Answer: The answer is the first choice, <L = <P
Step-by-step explanation:
There are two triangles.
Triangle LMN
and
Triangle PQR
If both of these triangles are congruent then that must mean that:
<L = <P
<M = <Q
<N - <R
Hope this helps!!
Answer:
(-1, 0)
Step-by-step explanation:
y = 2x + 2
y = x + 1
Substitute one of the equations for the value of y.
x + 1 = 2x + 2
-x + 1 = 2
-x = 1
x = -1
Now, substitute this value for x in one of the equations.
y = 2(-1) + 2
y = -2 + 2
y = 0
So, the solution is (-1, 0)
