Need help asap!! (summer packet)
DiKsa [7]

Part A:

Function A:

Slope = (7-3)/(5-3) = 4/2 = 2

Equation:

y - 3 = 2(x - 3)

y - 3 = 2x - 6

y = 2x - 3

Funcion B:

(0, 3 ) and (-5, 0)

Slope = (3 - 0)/(0 + 5) = 3/5

y-intercept (0,3) so b = 3

Equation:

y = 3/5 x + 3

Function C:

y = 3x + 1

Part B:

Rate of change is the change in y over the change in x (rise/run). It's also the slope

Function A:     rate of change = 2

Function B:     rate of change = 3/5 (smallest)

Function C:     rate of change = 3   (largest)

Order linear functions based on rate of change from least to greatest.

Function B:             y = 3/5 x + 3

Function A:             y = 2x - 3

Function C:             y = 3x + 1

Find the area of the following figure.
Rus_ich [418]

Answer:

A. 312 cm²

Step-by-step explanation:

The figure compromises of a rectangle and 2 equal triangles.

Area of the figure = area of the rectangle + area of the two triangles

Area = L*W + 2(½*b*h)

Where,

L = 16 cm

W = 12 cm

b = 12 cm

h = 10 cm

Plug in the values

Area = 16*12 + 2(½*12*10)

= 192 + 120

= 312 cm²
