Figure abcd is a parallelogram.
which sequence could be used to prove that ad = bc?
o first prove aabc is congruent to acda, and then
state ad and bc are corresponding sides of the
triangles
o first prove a abc is similar to acda, and then state
ad and bc are opposite sides of the parallelograms
o first prove abcd is congruent to cdab, and then
state ad and bc are corresponding sides of two
parallelograms.
o first prove abcd is similar to cdab, and then
state ad and bc are opposite sides of the
parallelograms

the probability that a bird is green (.30) is true

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
