Inequalities are just like regular equations with only one exception. Which is when yo multiply or divide by a negative number to both sides of the inequality sign you must flip it. But, for this inequality that rule will no apply. So, what I do to make it easier because I know we all see a different sign in an equation and we start to freak out. So, change the inequality sign to an equals sign to get a hang of working with them.
Example of changing an inequality sign to an equals sign:

Addition property of equality

or
Example of keeping the inequality sign

Addition property of equality

Answer:
A.
Step-by-step explanation:
81 - 16 = 65
81 - 16 = 65
formula c^2 = a^2 - b^2
c^2 = 81 - 16
√c^2 = √ 65
c = √ 65
Answer:
A, C, and F
Step-by-step explanation:
Answer:
It got cut off, but the approximate y intercept is 3 and slope intercept form is
y = x + 3 and I used the points 0,3 and 3,6 to calculate the slope using the slope equation y1 - y2/x1 - x2
Hope this helped and brainliest please!
