It helps you determine the characteristics of the plot/graph. I am not sure so it is your choose.
Answer:
Step-by-step explanation:
Alberto is correct in reasoning that all lines and rays are congruent to each other but incorrect in his reasoning about the line segments.
Line segments are equal in measure only when they are equal in length. They can have any orientation on a plane.
Since, AB = 3 units
CD = 4 units
Therefore, AB ≠ CD
Error in AB ≅ CD
Answer:
$492 per year
Step-by-step explanation:
The first step we take towards solving this question is to add all the numbers we were given as money spent(excluding that of the month)
$20 + $10 + $18 + $3 = $41 per month
This means that a total of $41 was spent per month.
Going further, since we're told it's 12 months, we then multiply it by 12, and thus, we have
$41 * 12 = $492 per year
Therefore, the total money spent is $492 per 12 months, or per year
Answer:
add 21 to both sides to get everything on one side
x^2 - 10x + 21 = 0
do factorization, guess and check
(x - 7) (x -3) = 0
x =7, and x =3
