The solution for C in terms of D and W is:

$C = \frac{W+4D}{3}$

Step-by-step explanation:

Solving a formula for a given variable means to isolate the variable on one side of the equation

Given equation is:

$W = 3C-4D$

We have to solve for C in terms of W and D

Adding 4D on both sides

$W+4D = 3C-4D+4D\\W+4D=3C$

Dividing both sides by 3

$\frac{W+4D}{3}=\frac{3C}{3}\\C = \frac{W+4D}{3}$

So,

The solution for C in terms of D and W is:

$C = \frac{W+4D}{3}$

x 0 1 2 3 y 8 1 −6 −13 Is the relationship a linear function? How do you know? A. No; the change in x and the change in y is not

iogann1982 [59]

Answer:

The correct option is C) Yes; the change in x is constant and the change in y is constant.

Step-by-step explanation:

Consider the table shown.

x y

0 8

1 1

2 -6

3 -13

Now observe the changes in x and y coordinates, if changes are constant then the given function is linear.

Consider the change in x coordinate.

1-0=1, 2-1=1 and 3-2=1

Now consider the change in y coordinate.

1-8=-7, -6-1=-7 and -13-(-6)=-13+6=-7

Since the change in x and y is constant the given relationship is linear.

Therefore, the correct option is (C) Yes; the change in x is constant and the change in y is constant.

What are the zeros of the quadratic function f(x) = 2x2 + 16x – 9?

Aleksandr-060686 [28]

Answer:

The zeros of the function are -0.488 and -7.39

Step-by-step explanation:

Given the quadratic function

f(x) = 2x²+16x-9

The zeros of the function is gotten at when f(x) = 0

2x²+16x-9 = 0

Using the general equation

x = -b±√b²-4ac/2a

From the equation, a = 2, b = 16 and c= -9

x = -16±√16²-4(2)(-9)/2(2)

x = -16±√256-72/4

x = -16±√184/4

x = -16+13.56/4

x = -16+13.56/4 and -16.13.56/4

x = --2.44/5 and -29.56/4

x = -0.488 and -7.39

Which is an equation of a circle with center (-10, 6) and radius 8?

kupik [55]

An equation of a circle:

(x - a)² + (y - b)² = r²

(a; b) - a coordinates of a center
r - a radius

r = 8; (-10; 6) ⇒ a = -10 and b = 6

subtitute

(x - (-10))² + (y - 6)² = 8²

Answer: (x + 10)² + (y - 6)² = 64
