The second option.
range is the set of y values.
if you put 0 and 8 in place of x, the options in 2 match up
wish I could help but don't now whatn you are saying
Solve the literal equation 2xy - xz = 4 for x
x = 4/(2y-z)
y =/ z/2
Answer:
1/2
Step-by-step explanation:
Cos 60 =
1/2 =
Multiplying both sides by 4
=> XZ = 2
Sin Y =
Sin Y =
Sin Y = 1/2
Lets say that the two unknown integers are
and
.
We know the following things about
and
:
And, we want to find
.
To solve this, we'll use the expansion of the squared of the sum of any two inegers; this is expressed as:
So, given what we know about the unknown integers, the previous can be written as:
We can easily solve for
:
The answer is 168.
Another approach to solve the problem is, from the two starting equations, compute the values of
and
, which are 12 and 14, and directly compute their product; however, the approach described is more elegant.
