Answer:
y = ⅘x - 41/5
Step-by-step explanation:
slope of the line from the origin = -5/4
slope of any perpendicular to the line = ⅘
equation of the line from the origin:
y = -(5/4)x
perpendicular to the line that passes through (4,-5):
y+5 = ⅘(x-4)
y = ⅘x - 41/5
Answer:
1 2/3
Step-by-step explanation:
First make all of them the same unit
1/12 and 9/12
Then sum all four sides together
20/12 = 10/6 = 5/3 = 1 2/3
Since you have the square root of x, you would need to square it to reverse the square root, and just have x. Then, you would have to square the 4 on the otherside, to get x=16
Answer:
$200.00
Step-by-step explanation:
12 widgets cost $30.00, meaning 1 widget costs ¢2.5. So then multiply 80 and 2.5, getting a total of $200.00.
