Step-by-step explanation:
287 - 7x = 14
-7x = 14 - 287
x = -273 ÷ -7
× = 39 dollars
Complete parenthesis and exponents from left to right is NOT PEMDAS.
You can do 16×60, or 60×16 or 60(16)
3 x-intercepts:
1) x = -1
2) x = 3
3) x = 4
D no solution at least there shouldnt be because when 5 is square rooted times itself it would equal 5 and then adding a variable would make it higher, so d no solution
