<span>x -3y=6
3y = x - 6
y = x/3 - 2
answer
</span>slope-intercept form of the equation: y = x/3 - 2
2x+4-3x>-1
-x+4>-1
-x>-1-4
-x>-5
X<-5/-1
Hence x<5
Answer:
9% fund: $
210,000
13% fund: $70,000
Step-by-step explanation:
As she wants to have a $28,000 annual return for her $280,000 investment, she is expecting a return rate of 10%:

If we call x the proportion of the capital in the 9% fund, then (1-x) is the proportion of the capital in the 13% fund,and the return of the combination has to be the expected return of 10%:

Then, we know that 75% of the capital should be invested in the 9% fund and 25% in the 13% fund.
This correspond to a capital of:
9% fund: 0.75*$280,000 = $
210,000
13% fund: 0.25*$280,000 = $70,000
I think this is more of an opinion than an actual answer
Answer: A
Graph cut the horizontal and vertical axis at 2 points A(0;5) and B(1.66666;0)
you calc x=0 in the answer and have y
you can choose A or B. Next, you calc y=0 into A,B. If x=1.6666666, your answer is A
