Answer:

Left 4 units

Step-by-step explanation:

h(x) is a line with slope 2.  Let's say it has y-intercept b.  So:

h(x) = 2x + b

d(x) is h(x) shifted up 8 units.  So:

d(x) = h(x) + 8

d(x) = 2x + b + 8

We want to shift h(x) left or right to get d(x).  If we say that shift is a units to the right, then:

h(x−a) = d(x)

2(x−a) + b = 2x + b + 8

2x − 2a + b = 2x + b + 8

-2a = 8

a = -4

a is negative, so the shift is to the left.

h(x) should be shifted to the left 4 units.

angle A and angle B are complementary angles. If m angle A = (x-16)degrees and m angle B = (3x+28)degrees, then find the measure
Ahat [919]

Answer:

4x \times 448

Step-by-step explanation:

A=

a = (x - 16)

b = (3x + 28)

So you add :

x \: and3x

To get

4x

Then you do :

16 \times 28

To get :

448

Answer is :

4x \times 448
