For lines to be parallel they must have the same slope. Since our reference line is y=5x-7 the parallel line must have the same slope, in this case 5.
So our parallel line thus far has the form:
y=5x+b, using point (-1,-3) we can find the y-intercept or "b"
-3=5(-1)+b
-3=-5+b
b=2 so the parallel line is:
y=5x+2
Answer:
Alex can buy "3" socks
Step-by-step explanation:
75- 25 =50
50- 29.99 = 20.01
20.01/ 6.26= 3.02
Since you can't get a portion of a sock you just take the first number (which is 3). Therefore, Alex can only buy three socks.
Answer: 3 3/7 hours
Step-by-step explanation:
you need to find out how much work they can do in an hour.
let x represent the total collaborative work
1/8 + 1/6 = 1/x
3/24 + 4/24 = 1/x
7x = 24
x = 24/7 or 3 3/7 hours (in decimal form this is 3.4286)
I cannot guarantee this is correct but hope it helped
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
Method 1: Calculate 40% discount on original price, then subtract discount from original price.
Amount of discount = 40% of $30
= 0.40 × $30
= $12
New price = $30 - $12 = $18
Method 2:
New price = (100% - discount percentage) of original price
= 60% of original price
= 0.60 × $30
= $18
