What is the value of 12x^-3 y-1 for x=-1 and y=5<br> A.-12/5<br> B.-180<br> C.-60<br> D.-5/12

Mkey [24]

Expressions are mathematical statements represented with the variables

The value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5

<h3>How to determine the value of the variable</h3>

The expression is given as:

$12x^{-3} y^{-1}$

When x = -1, the expression becomes

$12 * -1^{-3} y^{-1}$

Evaluate the exponent

$- 12 y^{-1}$

When y = 5, the expression becomes

$- 12 * 5^{-1}$

Evaluate the exponent

- 12/5

Hence, the value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5

last month, a bookstore ran the following at and sold 85 calculators, generating $4,083 in sales. How many of each type of calcu

Scilla [17]

Answer:

31 scientific calculators

54 graphing calculators

Step-by-step explanation:

X = number of $15 calculators

Y = number of $67 calculators

X+Y = 85 then X = 85-Y

15X+67Y = 4083

substitute for X

15(85-Y)+67Y = 4083

1275 - 15Y + 67Y = 4083

reduce

52Y = 2808

Y = 54

X = 31

(f(1) = -16<br> | f(n) = f(n-1).<br> f(3) =

Sauron [17]

Answer:

f(3) = -16

Step-by-step explanation:

f(1) = -16

f(n) = f(n-1)

f(2) = f(2-1) = f(1) = -16

f(3) = f(3-1) = f(2) = -16
