Step-by-step explanation:

We can multiply both by 8

So, 8x and -24

So its correct

2We multiply 8 by both

So, we have 8x-192

So, no

FIrst, we can do 9 and apply it to both x and -3

So, 9x-27-x+3

So, 8x-24

SO, yes

4

5+3*x = 8x

So, 8x-24

So yes

On a large baking tray, 40 cookies can be baked together. To bake 40 cookies it takes 14 minutes, for baking 80 cookies it takes 28 minutes, for baking 100 cookies it takes 42 minutes. How much time will it take to bake 140 cookies?

A-49 B-56 C-57 D48

Answers

the answer is B (56) because it states that it takes 14 minutes to bake 40 cookies, and you already have 100 cookies so you would just add the time it took to bake 40 cookies which would be 42+14=56

Hey! can you guys please solve all correctly? i need them asap btw, thanks! (I will give brainliest and 15 points)

Answers

The answer should be D because whenever x is bigger than 5 then the left side would be bigger than 2.

Consider the following quadratic equation. f(x) = 9x^2
Part A: Write a function, g(x), the shifts f(x) down by 3 units.
Part B: Write a function, h(x), that vertically stretches f(x) by 6 units.
Part C: Write a function, m(x), that reflects f(x) about the x-axis.

Answers

Answer:

[tex]g(x) = 9x^{2} -3[/tex][tex]h(x) = 54x^{2}[/tex][tex]m(x) = -9x^{2}[/tex]

Explanation:

[tex]f(x) = a(x-h)^{2} + k[/tex]

a:

Determines direction.Negative x reflects over x-axis.a < 1 --> vertically shrunk.a > 1 --> vertically streched.

h:

Determines left and right.Sign of h flips...(x + h) goes left.(x - h) goes right.

k:

Determines up and down.

A basketball has a mass of 1 kg and is traveling 12 m/s.

What would happen to the velocity if the momentum of the basketball were cut in half?

Answers

Answer:

[tex]6\:\mathrm{m/s}[/tex] (The velocity would also be halved)

Step-by-step explanation:

The momentum of an object is given as [tex]p=mv[/tex] where [tex]m[/tex] is the mass of the object and [tex]v[/tex] is the velocity of the object.

Because mass is constant, if the momentum ([tex]p[/tex]) was cut in half, the velocity of the basketball would also be halved:

Let [tex]p_1[/tex] be the initial momentum and [tex]p_2[/tex] be the final momentum:

[tex]\frac{1}{2}p_1=p_2,\\\frac{1}{2}mv_1=mv_2, \\\fbox{$\frac{1}{2}v_1=v_2$}[/tex]

Therefore, the basketball's new velocity is [tex]\frac{1}{2}\cdot 12=\fbox{$6\:\mathrm{m/s}$}[/tex].

a basketball has a mass of 1kg and is traveling 12 m/s
6 m/s
