An alloy of metals is 50% iron. Another alloy is 40% iron. How much of each should be mixed to make 600 grams of an alloy that is 43% iron?

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
