Answer:

Step-by-step explanation:

1. s<span>olve the proportion k/5=5/125.
First reduce 5/125.
5/125 = 1/25
Now you can cross multiply.
25k = 5
k = 5/25
k = 1/5
</span><span>d) 1/5
2. </span><span>round the answer of 0.4x-0.2=2.5 to two decimal places.
</span>0.4x=2.7
x = 6.75
<span>b) -6.75
3. </span><span>what is the y-intercept of 4x-3y=-12?
The y-intercept is when x = 0.
4(0) - 3y = -12
-3y = -12
y = 4
</span>d) 4
