Which graph represents a function

The relationship between the cost of cookies and the number of cookies is

a proportional relationship.

Correct response:

The function of the given graph for the cost of cookies at store A is found as follows;

The graph is a straight line passing through the origin, therefore, the equation is of the form;

y = m·x

The cost of 2 cookies = $0.5

Therefore;

The cost of 1 cookie at store A = $0.5 ÷ 2 = $0.25

Therefore, the cost of y cookies = 0.25·x

Where;

x = The number of cookies

The equation representing the cost y for x cookies in store B in dollars is given as follows;

y = 0.30·x

Therefore, the cost of 1 cookie at store B = $0.30 × 1 = $0.30

Therefore;

Answer:

8.5

Step-by-step explanation:

15x+10+6x+2=180 (add up to we 180 because they are alternate eachother

21x+12=180 combine like terms

21x=178 subtract 12 from both sides

x~~8.5 divide both sides by 21

Answer:

A customer would have to own a cell phone for 5 months in order for the two companies to be equal.

Step-by-step explanation:

Given that:

Cost of cell phone at Verizon = $300

Monthly fee = $40

Let,

x be the number of months

V(x) = 40x + 300

Cost of cell phone at T-mobile = $200

Monthly fee = $60

T(x) = 60x + 200

For equal amount of money,

V(x) = T(x)

40x+300=60x+200

300-200=60x-40x

100=20x

20x=100

Dividing both sides by 20

[tex]\frac{20x}{20}=\frac{100}{20}\\x=5[/tex]

Hence,

A customer would have to own a cell phone for 5 months in order for the two companies to be equal.

9.)  Dilation with the center at the origin and a scale factor of 2.

10.) Dilation with the center at the origin and a scale factor of 1/3.

Step-by-step explanation:

PAGE 1

3.)  d

b/c the rule for x-axis is (x,y) --> (x, -y)

One of the points is (1, 1) ==> (1, -1)

4.) The rule for y-axis is (x, y) --> (-x, y)

A(-5, 3) --> A'(5, 3)

B(2, 6) --> B'(-2, 6)

C(-1, -7) --> C'(1, -7)

PAGE 2

5.) The rule for x-axis is (x,y) --> (x, -y)

A(-5, 3) ---> A'(-5, -3)

B(2, 6) ---> B'(2, -6)

C(-1, -7) ---> C'(-1, 7)

6.) The rule for 90 degrees clockwise is (x, y) --> (y, -x)

B(3, 4) ---> B'(4, -3)

PAGE 3

1.) On the transitions right is positive and left is negative

So 2 units to the right = +2

And 9 units down = - 9

So (x, y) --> (x + 2, y - 9)

2.) A is wrong b/c that translation is (x, y) ---> (x + 3, y -3)

B is wrong b/c the translation is (x, y) ---> (x + 3, y + 3)

C is wrong b/c the translation is (x, y) ---> (x - 3, y + 3)

D is correct b/c the translation is (x, y) --->(x -3 , y -3)

A(6, 6) --> A'(3, 3)   B(7, 4) --> B'(4, 1)    C(4, 4) --> C'(1, 1)

PAGE 4

7.) The rule for 90 degrees rotation counterclockwise is (x, y) --> (-y, x)

The correct graph would show A(-3, 3) ----> (-3, -3)

The only graph that shows this is Graph C

8.) The rule for 180 degrees rotation is (x, y) ----> (-x, -y)

The correct graph would show A(-3, 3) ----> A'(3, -3)

Graph B is the only one that ALL the angles follow this rule

PAGE 5

9.) It is Dilation with the center at the origin and a scale factor of 2.

B/c --> A(3, 3) ---> A'(6, 6)     B(2, 0) ---> B'(4, 0)    C(5, 2) ---> C'(10, 4)

(3*2= 6, 3*2=6)     (2*2= 4, 0*2= 0)      (5*2= 10, 2*2= 4)

10.) It is Dilation with the center at the origin and a scale factor of 1/3

B/c ---> A(-3, 6) --> A'(-1, 2)   B(12, 3) ----> B'(4, 1)   C(-6, -6) ---> C'(-2, -2)

(-3*1/3= -1, 6*1/3= 2)         (12*1/3= 4,  3*1/3= 1)        (-6*1/3= -2, -6*1/3= -2)

Given :

Total amount of pudding made, T = 5 pounds.

Size of each cup, s = 4 ounces.

To Find :

How many total individual pudding cups can Harper make.

Solution :

Let, n number of pudding cups can filled with 5 pounds pudding.

We know, 1 pound = 16 ounces.

So, 5 pounds = 16×5 = 80 ounces.

Now,

[tex]n = \dfrac{80}{s}\\\\n = \dfrac{80}{4}\\\\n = 20 \ cups[/tex]

Therefore, 20 cups can be filled with 5 pounds of pudding.

Answer: The odds of getting tails twice in a row are 1/2 * 1/2 = 1/4. So 25% of the time you'll get heads twice in a row. But, if you've already flipped a coin 99 times, and gotten heads each time, then the odds of your next flip being heads is still just 50:50.
