Answer:
C - Has a positive rate of change
Step-by-step explanation:
Add the whole numbers 4 + 3 = 7
Add the fractions 1/2 + 1/4
Rewrite 1/2 to have a common denominator with 1/4
1/2 = 2/4
Now add 2/4 + 1/4 = 3/4
The answer would be 7 3/4
Answer:
A. every point on the line is a "point of intersection"
Step-by-step explanation:
Two lines are defined as collinear if they lie along the same straight line, which also means that the two lines completely overlap at any point. As a consequence, each point of one line touches a point of the other line, so every point on the line corresponds to a point of intersection between the two lines.

Answer:
16. D
17. 5^-1 · 5^-1 and 25^-1
8^0 · 8^3 and 8^3
Step-by-step explanation:
When you multiply two same numbers with exponents, just think of it as adding up exponents.
When you divide two same numbers with exponents, just think of it as subtracting exponents.
If a parenthesis has an exponent outside, then every exponent inside the parenthesis will be multiplied by that outside parenthesis.
(5^-1)^-2 · 5^3 ÷ 5^7
5^2 · 5^3 ÷ 5^7
5^5 ÷ 5^7
5^-2
When exponents are negative, you have to flip them or put them on the other side
5^-2 = 1/5^2 = 1/25
Let's try to find the equivalent pairs
6^7 ÷ 6^-2 = 6^5
6^9 = 6^5 Not equivalent
(6^3)^0 = 6
6^0 = 1 (Any number with a zero exponent is always 1)
1 = 6 Not equivalent
5^-1 · 5^-1 = 25^-1
5^-2 = 25^-1
Flip em
1/5^2 = 1/25
1/25 = 1/25 Equivalent
8^0 · 8^3 = 8^3
8^3 = 8^3 Equivalent
4^-3 ÷ 4^2 = 4^5
4^-5 = 4^5 Not equivalent
