Answer:
b. (-1, 5)
Step-by-step explanation:
Since the first equation is already solved for y, we can use substitution.
Substitute y in the second equation with 3x + 8.
5x + 2y = 5
5x + 2(3x + 8) = 5
5x + 6x + 16 = 5
11x = -11
x = -11/11
x = -1
Now substitute x in the first original equation by -1 and solve for y.
y = 3x + 8
y = 3(-1) + 8
y = -3 + 8
y = 5
Answer: (-1, 5)
Answer:
3
Step-by-step explanation:
5 is greater than 2 and two is negative so the answer is positive
12^2 + 6^2 = x^2
144 + 36 = x^2
180 = x^2
13.416407865 = x
rounded
x = 13.4
For every hour. It will leak a half of cup (1/2). If 30 mins= 1/4 of a cup. Times it but two. 60 or 1 hour = 2/4 or simplified 1/2
Answer: y =21; x = 7√3
have: cos 60° = x/(14√3) = 1/2 => x = 1/2. (14√3) = 7√3
sin 60° = y/(14√3) = (√3)/2 => y = (√3)/2 . 14√3 = 21
