Answer:
C
Step-by-step explanation:
Because the line is straight and the line is supposed to be going straight up
L-5=w and (L)(W)=24
From there you can use elimination or substitution to solve... You should get
L=8
W=3
Answer:
80.0
Step-by-step explanation:
Answer:
<em>Equation:
</em>
<em>HCL + HCL = HCL
</em>
<em><u>0.30x + 0.45(50-x) = 0.35*50
</u></em>
<em><u>Multiply thru by 100 to get:
</u></em>
<em><u>30x + 45*50 - 45x = 35*50</u></em>
<em><u>-15x = -10*50
</u></em>
<em><u>x = (2/3)50
</u></em>
<em><u>x = 33 1/3 liters (amt. of 30% solution needed in the mixture)
</u></em>
<em><u>50-x = 16 2/3 liters (amt. of 45% solution needed in the mixture)
</u></em>

Answer:
y = 2x
Step-by-step explanation:
Parallel line share the same slope, therefore we can put any parallel line of y = 2 (x + 1) in equation as: y = 2x + k
As the parallel has to intercept with point (2/3, 1/3), simply put the coordinate into the equation to get value of k
2/3 = 2(1/3) + k
k = 0
Therefore the equation of this parallel line is y = 2x
