The equations that can be used to represent this situation are y = 13x and

y = 11x + 20.

Step-by-step explanation:

Given that,

Jenna travels at a speed = 13 miles per hour.
Alex travels 20 miles from her home at a speed = 11 miles per hour.

To find the total distance traveled by Jenna :

where,

y represents the total distance.
x represents the number of hours.
Speed of Jenna is 13 miles per hour.

Distance = Speed $\times$ Time

y = 13x

To find the total distance traveled by Alex :

where,

y represents the total distance.
x represents the number of hours.
Speed of Alex is 11 miles per hour.
Alex travels an additional 20 miles from her home to reach Jenna.

Distance = Speed $\times$ Time

y = 11x + 20

Suppose g(x)=f(x-3)-4. which statement best compares the graph of g(x) with the graph of f(x)

saw5 [17]

Answer:

D.) The graph of g(x) is shifted 3 units right and 4 units down

Step-by-step explanation:

When a number is added directly to an "x" variable, the graph of the function shifts to the left. When this number is negative, the graph shifts to the right. Therefore, if a -3 is directly modifying the "x" variable, the graph shifts 3 units to the right.

When a number is added to the overall function, the graph of the function shifts up. When this number is negative, the graph shifts down. Therefore, if a -4 is being added to the overall function, the graph shifts down 4 units.

Suppose that a person with a push mower can mow a large lawn in 5 hours, whereas the lawn can be mowed with a riding lawn mower

Reil [10]

------------------------------------------------------------------
Push Mower
------------------------------------------------------------------
It takes 5 hours to complete the job
1 hour = 1/5 of the job

------------------------------------------------------------------
Riding Lawn Mower
------------------------------------------------------------------
It takes 3 hours to complete the job
1 hour = 1/3 of the job

------------------------------------------------------------------
Push Mower + Riding Lawn Mower
------------------------------------------------------------------
1 hour = 1/5 + 1/3
1 hour = 3/15 + 5/15
1 hour = 8/15 of the job.

------------------------------------------------------------------
Calculate time needed to complete
------------------------------------------------------------------
8/15 of the job takes 1 hour
8/15 of the job = 1 hour

------------------------------------------------------------------
Divide by 8/15 on both side
------------------------------------------------------------------
8/15 ÷ 8/15 of the job = 1 ÷ 8/15 hour
Whole of the job = 1 x 15/8 hours
Whole of the job = 15/8 hours
Whole of the job = 1 7/8 hours

------------------------------------------------------------------
Answer: 1 7/8 hours

(k+1)(k-5)=0 find for 0

Tems11 [23]

K=-1 or k=5

either quantity could equal zero, so put each quantity equal to zero and solve for k.

hope this helps :)
