Answer:
infinitely many solutions.
Step-by-step explanation:
y=4x
y-4=4 (x-1)
Lets substitute the first equation into the second equation.
4x -4 = 4(x-1)
Distribute
4x-4 = 4x-4
Subtract 4x from each side
4x-4x-4 =4x-4x-4
-4=-4
This is always true. X can be anything. We have infinite solutions
Answer:
1 + 5(77 - s) = 31
Step-by-step explanation:
Solve for s:

Put the value of <em>s</em> to the expression 1 + 5(77 -s):

Use PEMDAS:
P Parentheses first
E Exponents (ie Powers and Square Roots, etc.)
MD Multiplication and Division (left-to-right)
AS Addition and Subtraction (left-to-right)

The answer is c. A right triangle is one where a^2 + b^2 = c^2, where c is the longest side.
