Whats is good estimate for the solution to the equation x³=95? how did you come up with ur estimate
dybincka [34]
Let x =4, so when you plug it in, you get: 4^3 = 64
and
Let x =5, so when you plug it in, you get 5^3=125

95 is in between 64 and 125, so an estimate of what x could be if x^3=95 would be around 4.5.
Hope this helped!(:

Which ordered pair is a solution for 2x+5y=-11<br> 10x+3y=11
svetlana [45]

Answer:

X = 2 and Y = -3

Step-by-step explanation:

2x+5y=-11    - equation 1

10x+3y=11    - equation 2

from equation 1, 2X = -11 - 5y

                           X = -11/2 - 5Y/2

                           X = -5.5 - 2.5Y

insert X = -5.5 - 2.5Y into equation 2

     therefore, 10x+3y=11

                       10(-5.5 - 2.5Y) + 3y = 11

                       -55 -25Y +3Y = 11

                        -22Y = 11+55

                      Y = -66/22

                      Y = -3

insert Y = -3 into equation 1

      thus 2x + 5(-3) = -11

              2x - 15 = -11

              2x = -11 + 15

              2x = 4

              x = 4/2

              x = 2

ordered pair: X = 2 and Y = -3

The stem-and-leaf plot represents the distances, in miles, people in an office drive to work each morning.
Oxana [17]
The answer should be 7. 7 People drive 20 miles of fewer to work. 
You can tell, by looking at the number of numbers across from the "1" in the "Stem" section.
Hope this helps!:)
