Answer:
a.
Step-by-step explanation:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).
Answer:
4b
Step-by-step explanation:
The GCF is the largest number that will multiply into each term. It can be both numbers and letters.
12b = 2*2*3*b and 40b^4 = 2*2*2*5*b*b*b*b has GCF 2*2*b = 4b
Get rid of negative exponents by remembering that x^-a= 1/x^a.
6^-3= 1/6^3
Evaluate the exponent
6^3= 216
Final answer: 1/216
Answer:
A = 4 units ^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the length of the base and h is the height
A = 1/2 ( 4) (2)
A = 4 units ^2
In this problem you use cosine because you know the hypotenuse and you want to know the adjacent side of the triangle. So in your calculator you would input cos(52). Then you would multiply that answer with the hypotenuse side. So your equation would be this: cos(52) x 13
