Answer:

y=-x+5

Step-by-step explanation:

(4,1)

(8,-3)

1)a slope of a line is (y2-y1)/(x2-x1)

  so (-3-1)/(8-4)

  -4/4=>m=-1

2)to find y-int replace any points in the equation by x and y

so    1=-1(4)+b

        1=-4+b

        1+4=b

so b= 5

therefore the equation is  y=-x+5   so d

The value of t that makes the factor e^(.032t) have the value of 2 can be found using logarithms.
  2 = e^(0.032t)
  ln(2) = ln(e^(0.032t)) = 0.032t
  t = ln(2)/0.032 ≈ 21.66

It would take 21.66 years for the cost to double.

All sides are congruent in quadrilateral ABCD below.
emmainna [20.7K]

Answer:

rhombus; Measure of angle B = 70 degrees

Step-by-step explanation:

The shape is a rhombus. Angle B and angle A are supplementary, so they add up to 180 degrees.

110 + B = 180

B = 180 - 110

B = 70

It is a rhombus because all sides are equal.
