Answer:
(x, y) = (8, -3)
Step-by-step explanation:
You can substitute for x in the first equation:
3(-3y -1) +3y = 15
-6y = 18 . . . . . add 3 and simplify
y = -3 . . . . . . . divide by -6
x = -3(-3) -1 = 8 . . . . find x using the second equation
The solution to this system of equations is (x, y) = (8, -3).

Answer:
I think it's 7
Step-by-step explanation:
-6 < 2T (-5+5) < 3+5
-6 < 2T < 8
+6 < 2T < 8 + 6
0 < 2T < 14
0 < ÷ 2 < ÷ 2
0 < T < 7
-0 < T < -0
T = 7
Using the probability concept, it is found that the correct statements are given as follows:
- The number of possible outcomes is 8.
- P(vowel) + P(consonant) = 1.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are eight letters, two of which are vowels and six of which are consonants.
Hence:
- P(consonant) = 6/8 = 3/4.
- P(vowel) + P(consonant) = 1/4 + 3/4 = 1.
E is one out eight letters, hence the probability is drawing the tile with E written on it is 1/8.
