Translate each equation into slope-intercept form. Then, state the slope and y-intercept . 4y=2x+20
likoan [24]

Answer:

           The slope-intercept form of the equation:  y = 0.5x + 5

           The slope:    m = 0.5

           The y-intercept:     b = 5

Step-by-step explanation:

Slope-intercept form is  y = mx + b, where m is the slope and b is y-intecept

4y = 2x + 20           {divide both sides by 4}

y = 0.5x + 5   ⇒   m = 0.5  and  b = 5

Kruka [31]

Answer:

  (x, y) ⇒ (x -2, y +2)

Step-by-step explanation:

Reflection across the line y = x+2 has the effect of interchanging x and y and translating by (-2, 2).

Reflection across the line y = x+4 has the effect of interchanging x and y and translating by (-4, 4).

The composition of these transformations is then ...

  (x, y) ⇒ ((x +2) -4, (y -2) +4) = (x -2, y +2)

Find the area and perimeter of the shaded figure
puteri [66]

Answer:

Area - 6 unit^2   Perimeter - 10 units

Step-by-step explanation:

The shaded figure is 3 units long and 2 units high.

L = 3  W = 2

A = LW

A = 3 x 2 = 6 unit^2

Perimeter = 2L + 2W

P = 2(3) + 2(2)

P = 6 + 4 = 10 units
