Hello,
if the aim is to factorise:
81x²-4y²=(9x)²-(2y)²=(9x-2y)(9x+2y)
But the sides may also be and an other expression....
Answer:
-b+√b^2-4ac÷2a
Step-by-step explanation:
-2+√(1)^2-4(2)(-2)÷4
so it a long process but here Is the answer
x=1÷4+1÷4√17
x=1÷4+-1÷4√17
Answer:
An equation in point-slope form that represents Byron’s distance from home, y, after x hours is y=4x+2
Step-by-step explanation:
Speed of Byron = 4 miles / hour
Distance traveled in x hours = 
Distance traveled in x hours = 4x
We are given that After half an hour of running, he is 2 miles from home
So, Total distance = 4x+2
So, y = 4x+2
Hence an equation in point-slope form that represents Byron’s distance from home, y, after x hours is y=4x+2
