Elizabeth and daniel are starting competing coffee roasting businesses. they each first buy a large coffee roasting machine and then spend money to buy coffee beans as they need them.

for daniel, these costs can be described by the equation y = 7x + 55 where y is total cost in thousands of dollars and x is the number of tons of coffee beans roasted.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

homozygous. one is homozygous, while two is heterozygous.

the answer is 1/4

step-by-step explanation:

the answer is 8/21
