a function is when each x has a y
a relation is when 1 x has more than 1 y which makes it invalid therefore not a function
Answer:
The Answer is = -1/36
Step-by-step explanation:
First of all we will evaluate the signs
-5/18 -(-1/4)
-5/18+ 1/4 (As negative into negative gives = positive)
then we will take LCM
LCM OF 18 AND 4 WILL BE = 36
-10+ 9/ 36
-1/36
The answer is B: moderate
3x - y = -4
3x - (-10) = -4 Substitute
3x + 10 = -4 Simplify
3x = -14 Separate numbers and variables
x = -14/3 Divide
2x - y = - 10
2x - (-10) = -10 Substitute
2x + 10 = -10 Simplify
2x = -20 Separate numbers and variables
x = -10 Divide
Answer:
divide 88 by the number of x
88/8= 11
X = 11
