Answer:
2x - 6y
Step-by-step explanation:
(5x – 2y) – (3x + 4y)
5x - 2y - (3x + 4y)
Distribute the - sign
5x - 2y - 3x - 4y
Group like terms
(5x - 3x) + (-2y - 4y)
Combine like term
2x - 6y
8.3%= 0.083
567.31 * .083 = 47.086 = 47.09
567.31+47.09= $614.40
Total cost is $614.40
You divided in the wrong order. The resulting image always goes first then the preimage is afterward.
scale factor = (new)/(old) = 10/8 = 1.25
<h3>Answer is choice B</h3>
The scale factor is larger than 1, so this means we have an enlargement going on.
Use the half angle identity, tan157.5=(1-cos315)/sin315
cos315=cos(-45)=√2/2, sin315=-√2/2
tan157.5=(1-√2/2)/(-√2/2)=(2-√2)/(-√2)=(2√2-2)/(-2)=1-√2
