Answer: r=6

Step-by-step explanation:

Because if 42 equals 7 times r you just have to divide 42 by 7.

Answer:

6

Step-by-step explanation:

42=7r

Switch sides

7r=42

Divide both sides by 7

\frac{7r}{7} =\frac{42}{7}

Simplify

r=6

Question is attached
rodikova [14]

Answer:

  x = 12

  perimeter = 124

Step-by-step explanation:

The midline RS is half the length of MN, so we have ...

  2×RS = MN

  2(x +3) = 5x -30

  2x +6 = 5x -30

  36 = 3x . . . . . . . . . add 30-2x

  12 = x . . . . . . . . . . divide by 3

__

The length RS is then ...

  RS = x +3 = 15

and the perimeter of QRS is ...

  P(QRS) = QR +RS +SQ = 25 +15 +22 = 62

The perimeter of QRS is half the perimeter of MNP, so ...

  P(MNP) = 2×P(QRS) = 2×62 = 124

The perimeter of ΔMNP = 124.

The function f(x) is shown in the graph.
anzhelika [568]

The function that describes the graph is an exponential function

<h3>How to determine the function type?</h3>

From the graph, we have the following highlights:

  • Initially, when x increases; y seem not to increase
  • Then, x and y increase at the same time
  • Finally, y increase and x seem not to increase

The above is the description of an exponential function

Hence, the function that describes the graph is an exponential function
