4. Mariana receives a $20 gift card for
downloading music and wants to
determine how many songs she can
purchase. Each downloaded song costs
$1.29
a.
Let m represents the number of songs
downloaded. Write an inequality that
represents this given situation?
b. What is the maximum number of songs
Mariana can download?

Answers

Answer 1

Answer:

inequality-    1.29m <20

maximum number of songs- 15 songs

Step-by-step explanation:

For the inequality, you see that she only has $20 so whatever she buys has to be below that so use the less than sign. You also see that each song is worth $1.29 so 1.29m. For the maximum number of songs, you divide 20 by 1.29 and just ignore the remainder.

The parabola opens upward has x = 2 as an axis of symmetry and contains the non -vertex points (1, 9) and (4, 27) write the equation in vertex form for this parabola .

Answers

Answer:

              f(x) = 6(x - 2)² + 3

Step-by-step explanation:

f(x) = a(x - h)² + k    - vertex form of the equation of the parabola with vertex (h, k)

"the parabola opens upward" means:  a>0

"the parabola has x = 2 as an axis of symmetry" means:  h = 2

so f(x) = a(x - 2)² + k

"the parabola contains the point (1, 9)" means:

9 = a(1 - 2)² + k

9 = a(-1)² + k

9 = a + k

k = 9 - a

"the parabola contains the point (4, 27)" means:

27 = a(4 - 2)² + k

so:

27 = a(2)² + 9 - a

27 = 4a + 9 - a

3a = 18

a = 6

and  k = 9 - 6 = 3

Therefore the vertex form for this parabola is:

                                      f(x) = 6(x - 2)² + 3

If f(x)=3x-4 and g(x)=x2 find the value of f(3)-g(2).

No it is not proportional. Since she brought the last apple for 1/2 the price, the equation won’t be linear (straight line) anymore so it won’t be proportional. Proportional means the same unit rate.

Clare cycled a total of 6.48 kilometers by making 4 trips to work. How many trips will Clare have to make to cycle a total of 8.1 kilometers?

Answers

Answer:

5 trips

Step-by-step explanation:

6.48 km = 4 trips

1 trip = 6.48km ÷ 4 trips

1.62km = 1trip

8.1 kilometers ÷ 1 trip = 8.1 kilometers ÷ 1.62km

8.1 kilometers = 5 trips

∴ 8.1kilometers covers 5 trips

Step-by-step explanation:

Lets Solve!

First we need to factor the left side of the equation. Both terms include x.

[tex]x^2-4x =0[/tex]

[tex]x(x-4) =0[/tex]

If we multiplied x by (x-4) we would be back at [tex]x^2-4x =0[/tex].

Set factors equal to 0.

x=0 or x−4=0

x=0 or x=4

Answer:

Step-by-step explanation:

Factor out the common terms from x²-4x. You can factor out x:

[tex]x(x-4)=0[/tex]

Multiplication can be seen as (_)(_). Rewrite:

[tex](x)(x-4)=0[/tex]

Set both equal to 0:

[tex]x=0\\\\x-4=0[/tex]

Simplify the second equation:

[tex]x-4=0\\\\x-4+4=0+4\\\\x=4[/tex]

So, x=0 or x=4
