You simply plug in the value of x in each equation to find y.
1)
y = 7 - 3(2)
y = 7 - 6
y = 1
2)
y = 18/2
y = 9

Answer:
4800 yards wide
Step-by-step explanation:
120 x 40=4800
You just substitute the value of x in the given equation:
f(x) = 2x^2 - 5
f(-4) = 2 (-4)^2 -5 = 27
f(x) : a name given to the equation
f(-4): refer to the equation when the value of the independent variable x has the value between the brackets.
Lets solve the equalities first.

The answer is C.
If a laptop originally costs $800 at purchase, and is then discounted by
10%, the remainder would be $720, given that 10% of $800 is $80.
Therefore, once then applying the credit card to reduce it another $150,
the final price of the laptop would come out to $570 once the
deductions are considered.
