Mathematics
1 answer:
Naddik [55]3 years ago

Answer:

C. y-1 = f(x)

Step-by-step explanation:

We can see the difference between the red and black graphs is that the red graph is one unit higher in the y direction. Since there are no other differences, it is not possible to change to the input of the equation and achieve the red graph. Therefore answers a and b are not possible. If D was the answer, the red graph would be mirrored across the x axis. Answer c can be rearranged to y=f(x)+1 which would increase f(x) by 1.

6 pounds of apples and 3 pounds of oranges cost 24 dollars.5 pounds of apples and 4 pounds of oranges cost 23 dollars. Set up a
vitfil [10]

Answer:cost of each pound of apple= $3

And cost of each pound of orange =$2

Step-by-step explanation:

Step 1

Let cost of apples = x

And cost of Oranges =y

Let 6 pounds of apples and 3 pounds of oranges cost 24 dollars be represented as

6 x + 3y= 24----- equation 1

Also, Let 5 pounds of apples and 4 pounds of oranges cost 23 dollars be represented as

5x+ 4y= 23----- equation 2

Step 2

6 x + 3y= 24----- equation 1

5x+ 4y= 23----- equation 2

Using substitution method to solve the equation

6 x + 3y= 24

24-6x=3y

y= 24-6x/3 = 8-2x

Y= 8-2x

Substituting the value of y= 8-2x  into equation 2

5x+ 4( 8-2x)= 23

5x+ 32 -8x= 23

32-23= 8x-5x

9=3x

x=9/3

x=3

Putting the value of x= 3 in equation 1 and solving to find y

6 x + 3y= 24

6(3) +3y= 24

18+3y=24

3y= 24-18

3y=6

y=6/3= 2

Therefore the cost of each pound of apple= $3

And cost of each pound of orange =$2

In a right triangle ABC angle B is the right angle and m angle C = 30 degrees if AC = 10 what is AB
Sindrei [870]

Answer:

  • AB = 5

Step-by-step explanation:

This is a 30°-60°-90° right triangle.

AC is hypotenuse, AB is opposite side to 30° angle.

We know that in such a triangle the side opposite to 30° angle is half the hypotenuse.

<u>So we have:</u>

  • AB = 1/2AC = 1/2(10) = 5
