Expressing y in terms of x is as follows:
y = 25x
They wanted to cut exactly 160 meters of wire from a huge spool. They mistakenly measured mass instead of the length.
x = length of wire in meters
y = weight of wire in grams
Therefore, using proportion
<h3>Proportional relationship:</h3>
Proportional relationship express values in ratios .Therefore,
3 meters wire = 75 grams of wire
x meters = y grams
cross multiply
75x = 3y
let's express y in terms of x as required
Therefore,
divide both sides by 3
y = 75x / 3
y = 25x

Answer:
6.5%
Step-by-step explanation:
Is means equals and of means multiply
Let P be the percent
P * 120 = 7.8
Divide each side by 120
P* 120/120 = 7.8/120
P = .065
Change to percent form
6.5%

Answer: No, the given transformation T is NOT a linear transformation.
Step-by-step explanation: We are given to determine whether the following transformation T : R² --> R² is a linear transformation or not :
We know that
a transformation T from a vector space U to vector space V is a linear transformation if for ∈U and a, b ∈ R
So, for (x, y), (x', y') ∈ R², and a, b ∈ R, we have
and
Therefore, we get
Thus, the given transformation T is NOT a linear transformation.
