f(t)=t²

f(x)=x²

g. is more complicated.

A store sells two different types of coffee beans; the more expensive one sells for $8 per pound, and the cheaper one sells for
Slav-nsk [51]
So,

Let the amount of the expensive coffee beans be x, and the amount of the less expensive coffee bean be y.

The number of pounds of coffee beans is 50.
x + y = 50

$8 times the amount of more expensive coffee beans plus $4 times the amount of less expensive coffee beans divided by 50 equals $6.50.
\frac{8x + 4y}{50} = 6.50

Now, all we have to do is use Elimination by Substitution.
x + y = 50

Subtract y from both sides.
x = 50 - y

Substitute 50 - y for x in the second equation.
\frac{8(50 - y) + 4y}{50} = 6.50

Distribute.
\frac{400 - 8y + 4y}{50} = 6.50

Collect Like Terms.
\frac{400 -4y}{50} = 6.50

Simplify.
\frac{4(100 -y)}{2*5^2} = 6.50
\frac{2(100 -y)}{5^2} = 6.50
\frac{200 - 2y}{25} = 6.50

Multiply both sides by 25.
200 - 2y = 162.5

Add 2y to both sides.
200 = 162.5 + 2y

Subtract 162.5 from both sides.
37.5 = 2y

Divide both sides by 2.
18.75 = y

Substitute in an earlier equation to solve for x.
x = 50 - y
x = 50 - 18.75
x = 31.25

Check.
31.25 + 18.75 = 50 lbs.

\frac{8x + 4y}{50} = 6.50
\frac{8(31.25) + 4(18.75)}{50} = 6.50
\frac{250 + 75}{50} = 6.50
\frac{325}{50} = 6.50
\frac{5^2*13}{2 * 5^2} = 6.50
\frac{13}{2} = 6.50
6.50 = 6.50 This also checks.

There were 31.75 pounds of the more expensive coffee bean and 18.75 pounds of the less expensive coffee bean.

What are the possible side lengths of a triangle
BartSMP [9]
Hey!
So to find this you have to add the 2 smaller lengths and see if they are larger than the largest length. 
3 + 5 is 8 and that is not greater than 9 so A is wrong
4 + 8 is 12 and it is larger than 10, so maybe...
6 + 9 is 15 and that is not larger than 17 so that is out
8+10 is 18 and that is equal to but not larger than 18 so that is out
Your answer is B!
Hope this helps!
