Step-by-step explanation:

a) Perimeter is equal to 2w + 2L

2(3x + 4) + 2(x + 3)

6x + 8 + 2x + 6

8x + 14

b) Put 5 in x's place

8×5 + 14

40 + 14

c) Area = (3x + 4) * (x + 3)

Put 4 in x's place

(3×4 + 4) * (4 + 3)

12 + 4 * 7

16 * 7

112

Find the rate of change for each set of ordered pairs. What is the average rate of change of all the sets?

valina [46]

Answer:

Rate of change for two ordered -pairs i,e $(x_1, y_1)$ and $(x_2, y_2)$ is given by;

$\text{Rate of change} = \frac{y_2-y_1}{x_2-x_1}$

(-1, 12) and (6, 26)

Then;

$\text{Rate of change} = \frac{26-12}{6-(-1)}$

$\text{Rate of change}(A) = \frac{14}{7} =2$

(-1, -9) and (3, 3)

Then;

$\text{Rate of change} = \frac{3-(-9)}{3-(-1)}$

$\text{Rate of change}(B) = \frac{12}{4} =3$

(12, 6) and (11, 13)

Then;

$\text{Rate of change} = \frac{13-6}{11-12}$

$\text{Rate of change}(C) = \frac{7}{-1} =-7$

Now, find the average rate of change of all the sets:

Average defined as the sum of all the observation to the number of observation.

$\text{Average rate of change of all sets} =\frac{A+B+C}{3} =\frac{2+3-7}{3} = -\frac{2}{3}$

Find the midpoint M of the line segment joining the points S = (-6, 4) and T = (0, -8).

AfilCa [17]

Step-by-step explanation:

the coordinates of the midpoint are the mean value between the coordinates.

M = ((-6 + 0)/2, (4 + -8)/2) = (-6/2, -4/2) = (-3, -2)
