Randy is on a diet. if randy loses approximately 3 pounds a week, which of these choices is a reasonable estimate of the amount of time it will take her to lose 17 pounds

Answer : The amount of time it take her to lose 17 pounds will be, 6 weeks.

Step-by-step explanation :

As we are given that Randy loses approximately 3 pounds in a week.

Now we have to determine the amount of time it will take her to lose 17 pounds.

As, 3 pounds weight Randy loses in = 1 week

So, 17 pounds weight Randy loses in =

                                                              = 5.6667 weeks ≈ 6 weeks

Thus, the amount of time it take her to lose 17 pounds will be, 6 weeks.

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
