Answer:
1/4
Step-by-step explanation:
I'm not sure if he wants the Dilution factor or the scale but anyway
CBA = 4 C'B'A'
Scale 1/4
<span>( 5, 2) and ( 6, 4)
slope m = (4-2)/(6-5) = 2
y = mx + b
b = y - mx
b = 2 - 2(5)
b = 2 - 10
b = -8
so now you have slope m = 2 and y intercept b = -8
equation
y = 2x - 8
answer
</span><span>a. y = 2x - 8</span>
First replace y with 15.
1/5x-10=30
Then just solve from there.
x=200
374.072
Step-by-step explanation:
Use a calculator
Amount decrease = 380 - 225 = 155
percent = 115/380 * 100 = 40.8 %
