The temperature that 12%C is hotter than 16%C is 4%C
Answer:
U cannot use factorisation method to solve this, we are to use formula method
Step-by-step explanation:
6x²+7x=1
98.75
Just do 0.25 (25%) times 395
its the same as doing 395 divided by 25
ANSWER
(-1,2)
EXPLANATION
The given quadratic expression is:

The coefficient of the quadratic term is already 1.
So we add and subtract the square of half the coefficient of x.

We factor the first three terms to obtain

This is now in the form:

where (h,k) which is equal to (-1,2) is the vertex.
Time = Distance/Speed
Let d represent the distance from home to the resort in miles.
Time To Resort = d/48
Time To Home = d/40
Total Time = Time To Resort + Time To Home
11 = d/48 +d/40 . . . . . . . . . . substitute known values & expressions
.. = d*(40 +48)/(40*48) . . . . add fractions
.. = d*11/240 . . . . . . . . . . . . . simplify
11*(240/11) = d . . . . . . . . . . . multiply by the inverse of the coefficient of d
240 = d
The Gomez family traveled 240 miles from their house to the resort.
