Answer:
see below
Step-by-step explanation:
Since your proof wants to show the slopes of AC and DF are equal using substitution, you want to show the ratios that define those slopes are equal. Those ratios are BC/AB and EF/DE. So, the missing step is the one saying those ratios are equal:
BC/AB = EF/DE
Answer:
a) (2, 8)
Step-by-step explanation:
The easiest way is to insert the coordinates into the inequality.
a) (2, 8)
b) (0, 1)
c) (3, 7)
d) (5, 8)
You could also plot the inequality and test the points. You would get a graph like the one below. Point (2, 8) is the only one that satisfies the inequality. Points (0, 1) and (3, 7) do not satisfy the inequality because they are on a dashed line.
<h3>Answer: Choice A</h3>
Why? Because the denominators are both the same at 2x+8. We can only add or subtract fractions when the denominators are the same. The general rule for adding fractions is
We have numerators A and B added together over a common denominator C. If we didn't have a common denominator, then we'd have to do a bit of algebraic manipulation to get both fractions to a common denominator. It doesn't have to be the lowest common denominator (LCD), though it's often more efficient that way.
