Given: ABCD is a parallelogram.
Prove: ZA and 2D are supplementary
By the definition of a parallelogram, AB // DC. AD is a
transversal between these sides, so ZA and 2D are
angles. Because AB and DC are
the same-side interior angles must be
by the same-side interior angles
theorem. Therefore, LA and 2D are supplementary

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
