Answer:
y= - 5/2x - 2
Step-by-step explanation:
Y=2/5x + 2
Making it perpendicular, the slope will change to it's reciprocal and swap operations (+ becomes -). 2/5 will be -5/2. We already know the y-intercept which is -2, so simply put, the equation in slope-intercept form is y = -5/2x - 2
Answer:
x=4
ME=9
AM=18
AE=27
Because m in the midpoint ME is double AM
2(4x-7)=5x-2 4(4)-7 5(4)-2 18+9
8x-14=5x-2 16-7 20-2 =27
<u>-5x -5x</u> =9 =18
3x-14=-2
<u> +14 +14</u>
<u>3x</u>=<u>12</u>

Consider the suggested option:
1) if in 20 gr. of 50% solution given, then pure salt in this mix is 0.5*20=10 gr., and pure water is 0.5*20=10 gr.
2) after Maya added 5 gr. pure salt is 10+5=15 gr. Total mass of mix is 15(pure salt)+10(pure water)=25 gr.
3) new solution is 15/25=0.6 or 60%.
Answer: 25 gr. of 60% salt solution.
Answer:
Each piece of ribbon lengths 2.55 feet.
Step-by-step explanation:
A 30-foot piece of ribbon that Elena has cut for a craft project. Then she cuts off 7 feet from this.
So, the remaining length of the ribbon for the craft project will be (30 - 7) = 23 feet.
Now, then she cuts the remaining piece into 9 equal lengths of feet each.
Hence, each piece of ribbon lengths 
feet. (Answer)
