Answer:
(A) In step 1, the slope of the line should be One-half
Step-by-step explanation:
Terri calculated the slope as (x1 -x2)/(y1 -y2). Her first error was using this formula, when she should have used ...
m = (y1 -y2)/(x1 -x2)
= (6 -3)/(4 -(-2)) = 3/6 = 1/2
The best of the offered descriptions is ...
<em> In step 1, the slope of the line should be One-half</em>
Answer:
a.323.03hrs,
b.No. Time not enough
Step-by-step explanation:
One team takes 
of the job per hour,
Team two takes 
of the job together.
#to get what times it takes the two to clean together, we find the LCM of their work rates:
#It takes the two13/4200 of the job per hour.
Combined work rate is thus 
Hence it takes the two teams 323.03hrs to clean the streets working together.
b.The crew team is set to begin in 1 week(7days). We therefore convert our time into days/weeks to verify viability;
Since one day equals 24hrs, the team will take
13.46days>7days
#NO, The time is not enough since 13.46days is higher than the 1week(7day) timeline.
It will take him 8 minutes to read 13 pages.
Answer:
The expression equivalent to 8 - (6r + 2) is -6r + 6 ⇒ A
Step-by-step explanation:
Let us solve the question
∵ The expression is 8 - (6r + 2)
→ Multiply the bracket by (-)
∵ (-) × (+) = (-)
∴ 8 - (6r + 2) = 8 - 6r - 2
→ Add the like terms
∵ 8 - (6r + 2) = (8 - 2) - 6r
∴ 8 - (6r + 2) = 6 - 6r
→ Switch the terms
∴ 8 - (6r + 2) = -6r + 6
∴ The expression equivalent to 8 - (6r + 2) is -6r + 6
