Answer:

D x2 + y2 = 4

Step-by-step explanation:

The following are the functions

y = 4

y = x - 4

y = x^2 - 4

but

x^2 + y^2 = 4 is not a function as there should be minimum one x value with two or more y values

But the above equation does not meet the criteria so this represent non-function

Evaluate 7(-4) - |-6| + |4|

Zanzabum

$\red { \green {\boxed {\boxed{Answer}}}}$

$= 7( - 4) - | - 6| + |4|$

$= - 28 - | - 6 | + |4|$

$= - 28 - 6 + |4|$

$= - 34 + |4|$

$= - 34 + 4$

$= - 30$

The absolute value of a real number a is a when a≥0, or -a when a<0. The absolute value of -6 is 6. The absolute value of 4 is 4.

notka56 [123]

Answer:

3 gulps

Step-by-step explanation:

In this problem, f(x) = 3. Plug this into the equation:

3 = -3x + 12

Solve for x:

3 - 12 = -3x + 12 - 12

-9 = -3x

-9 / -3 = -3x / -3

3 = x

CosA.cos2A.cos4A=sin8A/8sinA

alexgriva [62]

I assume you're supposed to establish the identity,

cos(A) cos(2A) cos(4A) = 1/8 sin(8A) / sin(A)

Recall the double angle identity for sine:

sin(2x) = 2 sin(x) cos(x)

Then you have

sin(8A) = 2 sin(4A) cos(4A)

sin(8A) = 4 sin(2A) cos(2A) cos(4A)

sin(8A) = 8 sin(A) cos(A) cos(2A) cos(4A)

==> sin(8A)/(8 sin(A)) = cos(A) cos(2A) cos(4A)

as required.
