Coefficients are the numbers in from with the variable, the constant is just a number and the degree is the exponent.
Answer:
y = 4/3x + 1
Step-by-step explanation:
slope = rise over run
slope = 4 rise 3 run
slope = 4/3
Answer:
$9 in change
Step-by-step explanation:
Find the total cost of his purchases:
28 + 28 + 85
= 141
Find how much change he received by subtracting this from 150:
150 - 141
= 9
So, he should have received $9 in change
For the proof here kindly check the attachment.
We are given that
. Also, the transversal is shown. Let us take the first case, that of 
and 
. Please note that all other proofs will follow in a similar manner.
Let us begin, please have a nice look at the diagram. We will see that and 
are vertically opposite angles. We know that vertically opposite angles are congruent. Thus, and are congruent angles.
=
Now, we know that and are alternate interior angles. We also, know that alternate interior angles are equal too. Thus, we have:
=
From the above arguments it is clear that:
= = .
Thus, =
We have proven the first instance. Please note that all other instances can be proved in a similar fashion.
For example, for 
and 
we can take and 
as vertically opposite angles thus making = . Now, and are alternate interior angles and thus and are equal. Thus, we have and .
