Answer:
A) 7x + 3y = -8
B) -4x - y = 6 Multiplying B) by 3
B) -12x -3y = 18 then we add A)
A) 7x + 3y = -8
-5x = 10
x = 2
y = -2
Answer is the first one (2, -2)
Step-by-step explanation:
Well, if
{bx - 6y = 18 and {2x - 3y = 9, you might want to try elimination
Multiply second equation by -2: bx - 6y = 18 and -2(2x - 3y = 9)
Simplified: bx - 6y = 18 and -4x + 6y = -18
Now if you add them you get: -4x + bx = 0
Then simplified: bx = 4x
divide by x: b = 4
Your final solution is b = 4.
Hope that helps!
The probability is 7/41.
We are looking for
P(multiple of 6 given 2 digit) = P(2 digit & multiple of 6)/P(2 digit)
There are 7 2-digit numbers that are multiples of 6 between 1 and 50, out of 50 numbers; P(2 digit & multiple of 6) = 7/50
There are 41 2-digit numbers out of 50; P(2 digit) = 41/50
This gives us 7/50 ÷ 41/50 = 7/50 × 50/41 = 7/41
I personally would say neither because they either aren't the same or there not equivalent.
Answer:
f(1/3) = 6
Step-by-step explanation:
f(x) =-3x+7
Let x = 1/3
f(1/3) =-3*1/3+7
= -1 +7
= 6
