Answer:
x = -2
Step-by-step explanation:
7x -6y = -20
y=1
7x - 6 = -20
7x = -14
x = -2
The hypotenuse is the longest side of a right angle triangle. Also,
hypotenuse² = base² + height²
Checking if the equation, Pythagoras theorem, is satisfied:
27² = 10² + 24²
729 ≠ 676
Thus, this is not a right triangle.
Answer:
1: 8 2/5
Step-by-step explanation:
4x5=20+3=23
3x5=15+4=19

Hi there! The answer is $104
To find our solution we only have to multiply the original price by 1.6 ( 100 % for buying + 60 % markup = 160%, so multiply by 1.6).
We get the following answer:

Therefore, the selling price for one camera is $104.
~Hope this helps you~
The second one (the one that begins in StartSet) represents a function because in an algebraic function, the x value may not repeat more than once
