It is 7 opposite is different and absolute value would be 7 also it is always positive
Answer:
<h2>
y = 16/25x³</h2>
Step-by-step explanation:
If y is inversely proportional to a^3, this is expressed as;
y∝1/a³
y = k/a³ where k is the proportionality constant
Given a=2, y=10, then 10 = k/2³
k = 10*2³
k = 80
Substituting k = 80 back into the formula;
y = 80/a³ ............. 1
Similarly, if a is directly proportional to x, then a ∝ x i.e a = kx
If x=4, a=20 then;
20 = 4k
k = 20/4
k = 5
Substituting k = 5 back into the formula;
a = 5x ....... 2
Substitute equation 2 into 1;
y = 80/a³
y = 80/(5x)³
y = 80/125x³
y = 16/25x³
<em>Hence the formula for y in terms of x is y = 16/25x³</em>

X=490..not sure.. sorry its wrong
IDK what i'm supposed to be looking at???
Answer:
0.9545
Step-by-step explanation:
Let an integer be x.
If x is increased by 15%, then the value of the number would be
115/100x=1.15x
If 1.15x is decreased by 17%, then the value of the number would be:
(100-17)/100×1.15x
83/100×1.15x=0.9545x
