Explain how the values of h and k in y=|x-h|+k affect the graph of y=|x|

Answer:

Horizontal shift:

For the parent function f(x) and a constant h, the function given by   g(x) = f(x-h)  can be sketched by shifting f(x) h units horizontally.

The values of h determines the direction of shifts:

If :

  • h>0, the parent graph shifts h units to the right
  • h < 0, the parent graph shifts h units to the left.

Vertical shifts:

For the parent function f(x) and  a constant k, the function given by  g(x) =f(x) +k  can be sketched by shifting f(x) k units vertically.

The value of k determines the direction of shifts;

if:

  • k > 0, the parent graph shifts k units upward, and
  • k < 0, the parent graph shifts k units downward.

Therefore, the values of  h and k in y=|x-h|+k affect the graph of y=|x| tells us how far the graph shifts horizontally and vertically.

Only two problems I don’t understand. Don’t just give me answer, explain too please.
marta [7]

Answer:

12. Option b: 20 is the correct answer.

13. Option a: A rose costs $1 more than a daisy is the correct answer.

Step-by-step explanation:

12. Given that:

15x+10y=700       Eqn 1

x+y=60      Eqn 2

To find x, we will eliminate y be multiplying Eqn 2 by 10

10(x+y=60)

10x+10y=600      Eqn 3

Subtracting Eqn 3 from Eqn 2

(15x+10y)-(10x+10y)=700-600

15x+10y-10x-10y=100

5x=100

Dividing both sides by 5

\frac{5x}{5}=\frac{100}{5}\\x=20

Hence,

Option b: 20 is the correct answer.

13. Given that:

5x+4y=32     Eqn 1

x+6y=22       Eqn 2

Multiplying Eqn 2 by 5

5(x+6y=22)

5x+30y=110     Eqn 3

Subtracting Eqn 1 from Eqn 3

(5x+30y)-(5x+4y)=110-32

5x+30y-5x+4y=78

26y=78

Dividing both sides by 26

\frac{26y}{26}=\frac{78}{26}\\y=3

Putting y=3 in Eqn 2

x+6(3)=22

x+18=22

x=22-18

x=4

Hence,

Option a: A rose costs $1 more than a daisy is the correct answer.

If 10 of the 50 apples are green than what percent of the apples are green
Andrew [12]
So the question here is just simply what percentage is 10 out of 50 correct? You would basically just do 10/50 times 100 which will give you 20 percent as your answer.

The dimensions of a rectangular piece of construction paper are 11.5 inches and 18 inches. Maggie folded the piece of paper alon
lozanna [386]
C

Use the formula of the Pythagorean theorem. a^2 + b^2 = c^2

a = 11.5
b = 18

11.5^2 + 18^2 = 456.25^2
Sqrt(456.25) to find c

c=21.36 in.
