First, simplify this system:
<span>2x = -10y + 6 and x + 5y = 3
by dividing the first equation by 2. Result: </span><span>x = -5y + 3
Subbing this into the 2nd equation, -5y + 3 + 5y = 3
This equation is always true, so this system has infinitely many sol'ns.</span>
Answer:
y=4/3+19/3
Step-by-step explanation:
When it asks for perpendicular it means your focusing on the slope.
Perpendicular means opposite of the current slope, so flip it and change the sign (-3/4 changes to 4/3). Next you will use the equation (y-y1)=m(x-x1)
y1=the y value given
x1=the x value given
m=your slope
(y-1)=4/3(x+4) Since the x point is minus a negative we get to change the sign to a positive. Next distribute the 4/3 to each term in the parenthesis.
y-1=4/3(x)+4/3(4)
y-1=4/3x+16/3 Now we add the one to both sides.
+1 +1 The one isn't in teh correct format to just add so first imagine it as 1/1. Now to get the bottom to have a 3 like in 16/3 we just multiply the top and bottom by 3.
Now we can add this to the 16/3
We can now put this back into our equation.
y=4/3+19/3
A reasonable estimate would be an estimate of 2.5 feet.
Answer:
9 3/8 tons
Step-by-step explanation:
The product is ...
(4 3/8 containers)(2 1/7 tons/container) = (35/8)(15/7) tons = 75/8 tons
= 9 3/8 tons . . . of sugar in the shipment
