Length = 34 cm

Width= 9 cm

Step-by-step explanation:

Let the width of the rectangle to be.........w

Length is 7 more than three times the width..........3w+7

Perimeter = 86 cm

Perimeter of a rectangle = 2(l+w)

Perimeter of the rectangle = 2 (w + 3w +7)

                                             = 2w +6w + 14

                                      86= 8w +14

                                       86-14 =8w

                                        72=8w

                                        72/8 =8/8w

                                          9=w

Width= 9 cm

Length = 3*9 + 7= 27+7 = 34 cm

You earn $9 per hour babysitting. This is $2 more than what you earned per hour last year. What did you earn last year?
slamgirl [31]
$7 is the correct answer for *per hour*, as 9-2=7. Notice how it says how much did you earn last year, implying total earned. How many hours did you work last year?

Answer:

  • minimum: -9
  • maximum: -6

Step-by-step explanation:

For a point to be a relative extreme, there must be points on both sides that are not as extreme. That is, the ends of the interval may be extreme values, but do not qualify as <em>relative</em> extrema, since there are not points on <em>both sides</em>.

In the interval [-3, 3], the relative extrema are the turning points.

The relative minimum is at y = -9 on the y-axis.

The relative maxima are at y = -6, between 1 and 2 on either side of the y-axis.
