Complementary angles add up to 90 (there should be a right angle in the diagram)

x+20+x+10 needs to equal 90 where x=30

Left angle is measured 30+20=50 degrees

Angle on the right is measured 30+10=40 degrees

Functions f(x) and g(x) are shown below. f(x) = x2. . g(x) = x2 - 8x + 16. In which direction and by how many units should f(x)

Aliun [14]

The original function is given by:
$f (x) = x ^ 2
$
We apply the following transformation:
Horizontal displacements:
Suppose k> 0
To move the graph k units to the right, we must graph f (x-k)
Applying the transformation for k = 4 we have:
$g (x) = f (x-4)

g (x) = (x-4) ^ 2

g (x) = x ^ 2 - 8x + 16$
Answer:
B. Right by 4 units

-3(k+7)-5k+4=23 what is the value of K?

skad [1K]

-3(k+7)-5k+4=23
-3k-21-5k+4=23
Get rid of the numbers that aren't being multiplied by k:
-3k-5k=23+21-4
Add like things:
-8k=40
Divide by -8 on both sides to get k by itself and to make the equation even:
k=-5
