Answer:
Step-by-step explanation:
An index number is a number which is raised to a power. The power, also known as the index, tells you how many times you have to multiply the number by itself. For example, 2^5 means that you have to multiply 2 by itself five times = 2×2×2×2×2 = 32. There are a number of important rules of index numbers: y^a × y^b = y.
Answer:
the Answer is C
Step-by-step explanation:
where x is a pen and y is a pencil. Because a pen is .40 more than a pencil we can write this in terms of pencils and extra .40:

Therefore, a pencil costs 0.35 and a pen costs 0.75. Combined, one of each costs 1.10 dollars.
Answer:
g(-4) = 8
Step-by-step explanation:
If x = -4, we would use the expression of the limit "if x is less than or equal to -1" since x is just that.
We would then plug in our x value into the expression and solve for g(x)
g(x) = -x + 4 --> -(-4) + 4 = 4 + 4 = 8
The answer 5 (1/4) because if you add 1 and a quarter to it then that would make it 6 and a half
