Answer: 36÷4=9
Step-by-step explanation:
Answer:
50 degrees
Step-by-step explanation:
Use the substitution method:
2x - 6y = -12
x - 2y = -8
Then x = 2y - 8
Substitute in the first equation:
2(2y - 8) - 6y = -12
4y - 16 - 6y = -12
-2y = 4
y = -2
Now substitute y in one of the two equations given you prefer:
For example x-2*(-2) = -8
x + 4 = -8
x = -12
The solutions are x = -12 and y = -2
Well we know that total percentages always equals 100 so x + 45 = 100. You should get x = 55%
your answer will be f(x)=113−kx,f(−3)=121
