Answer:
y+4=-2(x-4)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-4)=-2(x-4)
y+4=-2(x-4)
The answer is. A) y=-4/5x-7
Just compare, and they will equal each other.
Let x represent the number of pounds of $10.75/lb coffee used in the mix.
.. 10.75x +3.25(100 -x) = 5.65*100 . . . . . . total cost of coffee blend
.. x(10.75 -3.25) = 100*(5.65 -3.25) . . . . . .separate x-terms from non-x terms
.. x = 240/7.5 = 32
32 pounds of $10.75/lb coffee should be used
68 pounds of $3.25/lb coffee should be used
The equation 3x+1/2=4
meaning x would equal 7/6
