Remark
The ratios are certainly correct but that doesn't mean that they show similarity. SSA is a very dangerous proposition to use. Redraw triangle DEF of that DF is going to upwards to your right hand side. Make E as it was before. Why isn't this right?
It isn't right because E has gone from being an acute angle to an obtuse angle (an angle larger than 90 but less than 180).
The ratios are still true, but the angles do not match. So the whole answer is incorrect.
5x+10
just distribute each value and multiply 5 to each of the values in the parentheses.
Answer:
The range is the set of all valid y values. Use the graph to find the range.
Interval Notation:
(−∞,∞)
Set-Builder Notation:
{y|y∈R}
Step-by-step explanation:
These fractions both have the same denominators so we can add them without having the equate them first.
The only thing you have to do is add the numerators (7 and 5), and keep the denominators the same.
7 5 12
-- + --- = ------
12 12 12
When you simplify 12/12 it becomes 1.
