that is the answer
Answer:
-10 degrees
Step-by-step explanation:
Width -
x ft.
Length -
(x+6)ft.
x(x+6)=315
x²+6x-315=0
a=1, b=6, c=-315
D=b²-4ac=36+4*1*315=1296, √D=√1296=36
For the width we can use only positive number.
The width =
15 ft.
The length =15+6=
21 ft.
Check :
Area =15*21=315 ft²

Approximation:
Step-by-step explanation:
Using the quadratic formula:
Answer:
The relation y=2x+8 is a function because the two different output values of the function have the one unique input value.
Step-by-step explanation:
The given relation is y=2x+8.
It is required to determine the relation is a function.
This solution can be obtained by using the concept of function. First write the given relation y=2x+8 and determine whether the given relation is a function.
Step 1 of 1
The given relation is y=2x+8.
This relation shows that the two different output values of the function have one unique input value and this relation is a linear function.
Hence, the relation is a function.
