true or false
the codomain of a linear transformation is a subset of the range.
if t is a linear transformation and v ∈ range(t), then there is at least one u in the domain such that t(u) = v
if t(x) is not a linear transformation, then t(rx) 6= rt(x) for all r and x.
if a linear transformation t : r3 → r3 is one-to-one, then it must be onto as well.
if t is a linear transformation, then t(0) = 0.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

if she was to only spend a dollar she can get 1lb
