Answer:
perpendicular
Step-by-step explanation:
The slope of y = 3x - 7 is 3.
3x + 9y = 9 → 9y = -3x + 9 → y = -1/3 x + 1 so its slope is -1/3.
This means that they are perpendicular because the product of their slopes is -1.
Answer:
D..... 3 lines of Symmetry
y = sin(360) = sin(0) = 0
answer: y=0
You can use the graph by drawing a unit circle centered about the origin. Then find the point and the corresponding y value.
Answer:
$1.21
Step-by-step explanation:
Start by finding the total amount spent on shirts. Do this by multiplying $3.65 and 4 together. You will get 14.6. So, he spent $14.60 on 4 shirts. Take this amount and subtract it from the total amount paid for shirts and socks. $23.07 minus $14.60. This will give you $8.47 left to spent on socks. $8.47 divided by 7 is $1.21. Therfore, James paid $1.21 per pair of socks.
