Answer:
<h2>-25b + 101</h2>
Step-by-step explanation:

Answer:
Step-by-step explanation:
y*1/x
y=k/x where k is the constant of variation
when y=7, x=-4
7=k/-4
k=-28
when x=5
y=-28/5
note: * is used as symbol of variation
<h3>The length in standard notation is 0.05 meter</h3>
<em><u>Solution:</u></em>
Given that,
Jeremy measured the length of an ant as 
We have to write the length in standard notation
From given,

Thus the length in standard notation is 0.05 meter
<em><u>Method 2:</u></em>

Use the exponent of 10 to determine how many places to move the decimal point
Since exponent is -2, is negative
Thus, we have to move the decimal point to right 2 places

Thus the length in standard notation is 0.05 meter
