Answer: 1
Step-by-step explanation:
Y2 - Y1 / X2 - X1
-2 - 1 = -3
-1 - -4 = 3
-3/3 = 1
Answer:
School X has 8 points and School Y has 2 points
Step-by-step explanation:
From first sentence
X - 6 = Y
From second sentence
X = 4Y
Hence substitute equation 1 into equation 2
4Y - 6 = Y
Y = 2
X = 4 x 2 = 8
19.83 x 1.07 = <span>21.218
$21.22</span>
Numerical expressions contain numbers, while algebraic expressions contain variables and numbers.
<u>Numerical Expression</u>
"Difference" indicates that we'll be subtracting 13 from 48.
48 - 13 = 35
<u>Algebraic Expression</u>
Variables represent the unknown number, in this case the difference between 48 and 13. Let d represent the difference between the two.
48 - 13 = d
35 = d
Additive inverses combine to get 0. So, k is -1.4. The sum is 0. Hopefully that will help.
