Step-by-step explanation:
For f(2), the input of the function is 2.
Let x = 2.
Evaluate.
Answer:
C
Step-by-step explanation:
I. a // b because m∠2 is on a 180° line, which splits the line into two sections, both being 90°. If m∠1=m∠2, then m∠1 is also 90°. The lines a and b are parallel from each other.
II. since m∠1 is 90°, and for a line to be perpendicular to the other line, they would have to be at a 90°. So, a⊥c because they intersect each other at a 90° angle.
Answer:
4.0
Step-by-step explanation:
To solve for this, simply add the values of people who prefer walking shoes and running shoes, since they are NOT tennis shoes.
runningshoes+walkingshoes=
6+9=15
Answer=D
Step-by-step explanation:
so, all 3 pieces together are 20 inches.
therefore,
x + 4x + 5x = 20
10x = 20
x = 2
so, the first piece is 2 inches long.
the second piece is 4×2 = 8 inches long.
the third piece is 5×2 = 10 inches long.
