Can you translate so I can help you out
The unit rate meant the slope, which is represented by m in y=mx+b
First we must isolate the y by dividing both sides by -1 to get:
y=-x/7 or y=(-1/7)x, so the the unit rate is -1/7 or B
Hope this helps :)
Answer:
C
Step-by-step explanation:
≤= black line w/ shading below the line
>= dotted line w/ shading above the line
2x+1= cross y-axis at +1 with a slope of two (for each unit to the right, move two units up)
-2x-3= cross y-axis at -3 with a slope of negative two (for each unit right, move two units down)
C shows where the two inequalities overlap.
10-3(x-4)=5(12-2x)
10-3x+12=60-10x
7x+22=60
Answer is B
I am pretty sure that it is table one because each number from the original recipe to the teachers recipe is multiplied by three.
