Is the relation a function?
{(-6, -1), (5,-1), (0, -1), (-2, -1), (3, -1)}

The cost for the whole group using distributive property to expand the expression and solve the problem is $28

Total cost of the group = Number of people including Kate(Cost of getting in per person) + (Number of people including Kate(Cost per ride per person)

= 4(5) + 4(2)

Answer:

25%

Step-by-step explanation:

Let p be the percent

Of means multiply and is means equals

p * 75 = 18.75

Divide each side by 75

75p/75 = 18.75 /75

p =.25

Change to percent form

p = 25%

Answer:

[tex]25\%[/tex]

Step-by-step explanation:

Let the percent as x

[tex]x \times 75 = 18.75 \\ 75x = 18.75 \\ \frac{75x}{75} = \frac{18.75}{75} \\ x = 0.25 \\ \\ \\ 0.25 = \frac{25}{100} = 25\%[/tex]

Answer:

The top one, that is the hyperbole.

The equation of hyperbola is      [tex]\frac{(y-5)^{2} }{9 } -\frac{(x-3)^{2} }{16 } = 1[/tex]

A plane curve generated by a point so moving that the difference of the distances from two fixed points is a constant : a curve formed by the intersection of a double right circular cone with a plane that cuts both halves of the cone.

• If the foci lie on the x-axis, the standard form of a hyperbola can be given as,

[tex]\frac{(x-h)^{2} }{a^{2} } - \frac{(y-k)^{2} }{b^{2} } = 1[/tex]

• If the foci lie on the y-axis, the standard form of the hyperbola is given as,

[tex]\frac{(y-k)^{2} }{a^{2} } -\frac{(x-h)^{2} }{b^{2} } = 1[/tex]

• Coordinates of the center: (h, k).

• Coordinates of vertices: (h+a, k) and (h - a,k)

• Co-vertices correspond to b, the ” minor semi-axis length”, and coordinates of co-vertices: (h,k+b) and (h,k-b).

• Foci have coordinates (h+c,k) and (h-c,k). The value of c is given as, c2 = a2 + b2.

• Slopes of asymptotes: y = ±(b/a)x.

According to the question

Foci = (3,7) (3,-3)

Vertices = (3,5) (3,-1)

As per coordinates and graph the hyperbola is vertical so x will be constant y varies

Distance between foci = 2c (where c is center)

10 = 2c

C = 5

Therefore Centre (h,k) = (3,5)

Distance between vertices = 2a

2a= 6

a = 3

The value of c is

[tex]c^{2} = a^{2} + b^{2}[/tex]

25 = 9 + [tex]b^{2}[/tex]

[tex]b^{2}[/tex] = 16

Now as per our equation

h=3 , k=5 , [tex]a^{2}[/tex] = 9, [tex]b^{2}[/tex] = 16

[tex]\frac{(y-k)^{2} }{a^{2} } -\frac{(x-h)^{2} }{b^{2} } = 1[/tex]

[tex]\frac{(y-5)^{2} }{9 } -\frac{(x-3)^{2} }{16 } = 1[/tex]

Hence, equation of hyperbola =    [tex]\frac{(y-5)^{2} }{9 } -\frac{(x-3)^{2} }{16 } = 1[/tex]

Answer:

1/5 = 20% not occupied.

Step-by-step explanation:

There are 72 occupied seats out of 90 total seats. We can say that there are 18 empty seats (90 - 72 = 18).

So there are 18 out of 90 seats occupied. We can rewrite that as 18/90. 18/90 simplifies to 9/45 = 3/15 = 1/5 = 20%.

As such, 20% of the seats are not occupied.

2. 0 apples left. Pauline took most apples

3. Nelly

4. Henry

Bonus. Carla - Leonard - Henry - Jenny

Step-by-step explanation:

1. From the picture, 41/45 > 80%

2. From the picture, 36/45 = 80%, therefore 80% + 20% = 100% of the apples were taken.

3. From the picture, 20/45 is between 40% and 50%, then 20/45 < 55%

4. From the picture, 15/45 is between 30% and 40%, then 15/45 < 40%

Bonus. Carla:  9/45 or 20%

Answer:

C

Step-by-step explanation:

You basically multiply the 2 functions together which gives you (2x + 3)(x + 1) = 2x² + 5x + 3

Answer:

The answer is C.

Step-by-step explanation:

Given that f(x) = 2x + 3 and g(x) = x + 1. So you have to multiply both functions together :

[tex]f(x) = 2x + 3 \\ g(x) = x + 1[/tex]

[tex]f(x) \times g(x)[/tex]

[tex] = (2x + 3)(x + 1)[/tex]

[tex] = 2x(x) + 2x(1) + 3(x) + 3(1)[/tex]

[tex] = 2 {x}^{2} + 2x + 3x + 3[/tex]

[tex] = 2 {x}^{2} + 5x + 3[/tex]

● A. True

O B. False

Answer:

The two functions are inverses.

Step-by-step explanation:

We are supposed to find whether the two functions are inverses.

[tex]f(x)=5x+4[/tex]

[tex]g(x)=\frac{x-4}{5}[/tex]

To find the inverse of f(x)

y = 5x+4

y-4=5x

[tex]\frac{y-4}{5}=x[/tex]

Replace x with y and y with x

So, [tex]\frac{x-4}{5}=y[/tex]

So, [tex]\frac{x-4}{5}=g(x)[/tex]

So,The two functions are inverses.

We realize x is 4.4 times  the size of  y as y is '0' so this means the negative value for x is 4.4 smaller than y.

Answer:

Property of equality division

Step-by-step explanation:

Given

c = d

b ≠ 0 then c∕b = d∕b

Required

State the property used

From list of options a through d, only option A best fits the description.

This is so because property of equality division is such that

given two variables c and d where c = d

[tex]\frac{c}{b} = \frac{d}{b}[/tex]

Provided that b ≠ 0

Take for instance;

b = 2; c = 8 and d = 8;

This implies that

[tex]c = d[/tex]

[tex]8 = 8[/tex]

Divide both sides by 2 (assumed value of b)

[tex]\frac{8}{2} = \frac{8}{2}[/tex]

[tex]4 = 4[/tex]
