Step-by-step explanation:

y — yı = m(x – xı) equation of a line

Points A(1,3) and B(2,1)

Slope (m) = (y2 – y1) / (x2 – x1)

(1 –3) / (2 – 1)

–2/1

–2

Thus, y –3 = –2 (x – 1)

y – 3 = –2x + 2

y –3 + 3 = –2x + 2 + 3

y = –2x + 5

Answer:

Five bags of dog food costs $21.25.

Step-by-step explanation:

We can solve using proportions.

$\frac{6 \: bags}{25.50 \: dollars} = \frac{5 \: bags}{x} \\ \\ \frac{127.5}{6} = \frac{6x}{6} \\ \\ 21.25 = x \\ 21.25 \: dollars = x$

I really need someone to help me out

All it takes for a relation to be a function is for each possible first number of a pair there's only one possible second number.

So if any of the sets has two pairs with the same first number, that one's not a function.

The last one has (3,2) and (3,5) so isn't a function.

Question 3 options:

melomori [17]

The height of an object can be represented as a function of time.

It takes the rocket 25 seconds to hit the ground

The height function is given as:

$\mathbf{h(t) = 400t - 16t^2}$

When the rocket hits the ground, we have:

h(t) = 0

So, the height function becomes

$\mathbf{ 400t - 16t^2 = 0}$

Rewrite as:

$\mathbf{ 16t^2 = 400t}$

Divide both sides by 16t

$\mathbf{ t = 25}$

Hence, it takes the rocket 25 seconds to hit the ground
