When you raise a number to a negative exponent, change the exponent to a positive and make the complete number a fraction with 1 as the numerator.
5 ^-2 = 1/5^2
The answer is C.

Answer:
The response that are true are:
- linear function has a constant additive rate of change, while a nonlinear function does not.
Since in linear function the rate of change is always equal as for a linear function we get a equation of line such that the slope is same.
- On a graph, the function must be a straight line to be linear.
Liner means there is a straight line of the function.
( Also it need not be true that the independent variable increases by 1.
There may be change of some other quantity in independent variable )
Answer:
Step-by-step explanation:
4s + 2j = 68........2j = -4s + 68........j = -2s + 34
3s + 3j = 81
3s + 3(-2s + 34) = 81
3s - 6s + 102 = 81
3s - 6s = 81 - 102
-3s = - 21
s = -21/-3
s = 7 <==== shirts cost 7 bucks
j = -2s + 34
j = -2(7) + 34
j = -14 + 34
j = 20 <===== jeans cost 20 bucks
Cost of airplane toy = $4.84
let x be the cost of the toy car
cost of airplane toy is 4 times the cost of toy car; it means
4x = $4.84
x = 4.84 / 4
x = 1.21
Thus, the cost of toy car is $1.21.
