A.All squares of 4 right angles
B.All parallelograms have 4 right angles
Y = -2x - 7
slope = -2 (parallel shares the same slope, -2)
Option A:
y = -2x + 7
slope = -2
At (3, 1)
y = -2(3) + 7 = 1
Answer: Option A
What is the question? no question has been asked. need more info to solve.
--Percent means out of 100, so 20% = 20/100
The prob in other words is asking
-- $60 is 20% of what number?
'$60' -- ---> 60
'is' -- ---> =
20% -- ---> 20/100
'of' -- ---> * (multiply)
'what number' ---> x (variable)
If they are looking to have them all simplified, this is how they should look.
4y - 4
4y + 4
4y + 1
