Middle square area= 8x8=64
one triangle area = (8x8)/2
multiply the triangel area by four and add the square area-- (4x32)+64=192
The square root of 81 is 9
Answer:
The equation of the function: y = mx + b
- m = slope = (y₂ - y₁)/(x₂ - x₁) = [5 - (-3)]/(4 - 0) = (5 + 3)/4 = 8/4 = 2
- b = y-intercept = -3
Therefore, the equation is <u>f(x) = 2x - 3</u>
When x = 0, f(x) = 2(0) - 3 = <u>-3</u>
When x increases by 1, f(x) increases by <u>2</u> (slope = the rate of change)
Answer:
y= -1/2x + 1/2
Step-by-step explanation:
First, use the point-slope formula: y-y1 = m(x-x1)
y-2 = -1/2(x-(-3))
y-2= -1/2x + -1.5
(subtract 2 from both sides)
y = -1/2x + 1/2
