Answer:

probably b

Step-by-step explanation:

I think for the other 3 answers, you are trying to have the x's have exponents, making them non-linear. While since b increases by 5 when x increases by 1, it is a linear function

Answer: The Answer Is (D.

Step-by-step explanation:

f(x) =

− 10

A function is linear if it can be expressed in the form f(x)= mx + b or if its graph is a straight line.

f(x)= mx + b

f(x) =

− 10

f(x) =

x − 10

parallelogram PQRS has PQ=RS=8 cm and diagonal QS= 10 cm. point F is on RS exactly 5 cm from S. let T be the intersection of PF

Doss [256]

<u>Solution-</u>

Given that,

In the parallelogram PQRS has PQ=RS=8 cm and diagonal QS= 10 cm.

Then considering ΔPQT and ΔSTF,

1- ∠FTS ≅ ∠PTQ ( ∵ These two are vertical angles)

2- ∠TFS ≅ ∠TPQ ( ∵ These two are alternate interior angles)

3- ∠TSF ≅ ∠TQP ( ∵ These two are also alternate interior angles)

<em>If the corresponding angles of two triangles are congruent, then they are said to be similar and the corresponding sides are in proportion.</em>

∴ ΔFTS ∼ ΔPTQ, so corresponding side lengths are in proportion.

$\Rightarrow \frac{PQ}{FS} =\frac{TQ}{TS} =\frac{TP}{TF}$

As QS = TQ + TS = 10 (given)

If TS is x, then TQ will be 10-x. Then putting these values in the equation

$\Rightarrow \frac{PQ}{FS} =\frac{TQ}{TS}$

$\Rightarrow \frac{8}{5} =\frac{10-x}{x}$

$\Rightarrow x=3.85$

∴ So TS = 3.85 cm and TQ is 10-3.85 = 6.15 cm

So 4 eggs is 2/3of 6 eggs, so to get the amount of milk we multiply the 3 cups by 2/3 (or just divide by 3 and multiply by 2) and get 2 cups of milk.
Hope this helps!
