*please be serious*<br> 3y = -x - 12<br> *solve for y

Anna [14]

Answer: $y=-\frac{1}{3}x-4$

Step-by-step explanation:

To solve for y, we want to make sure y is isolated. SInce y is already isolated, all we need to do is divide both sides of the equation by 3.

$3y=-x-12$ [divide both sides by 3]

$y=-\frac{x}{3} -4$ or $y=-\frac{1}{3}x-4$

The cable is 25 feet long! draw a diagram use the pythagorean theorem (a^2+b^2=c^2) to find the length of the cable (or in other cases, the hypotenuse)

Find the exact volume of a cylinder with a radius of 4 inches and a height of 3 inches?

Rina8888 [55]

Volume formula for cylinder is pir^2h. So that will be 4 times 4 times 3 times. That will be 48 cubic inches. However you still have pi left but if we were to multiply 3.14 by 48 we’ll get around 150 but that isn’t answer choice so go with 48.

Question 7(Multiple Choice Worth 1 points)

lana66690 [7]

Answer:

Option A.

Step-by-step explanation:

The given function is

$f(x)=0.15x^2-6x+400$

Leading coefficient is positive, so it is an upward parabola. Vertex of an upward parabola is the point of minima.

Vertex of a parabola $f(x)=ax^2+bx+c$ is

$Vertex=\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)$

In the given function a=0.15, b=-6 and x=400.

$-\dfrac{b}{2a}=-\dfrac{-6}{2(0.15)}=20$

At x=20,

$f(20)=0.15(20)^2-6(20)+400=340$

So, minimum value of f(x) is 340 at x=20.

From the given table it is clear that the minimum value of g(x) is 55 at x=70.

Since 55 < 340, therefore, g(x) has a lower minimum values, i.e, (70,55).

Hence, option A is correct.
