you save $15 per week to purchase a bike that costs $120. write and solve an inequality to find the number of weeks you need to save to purchase the bike.

Answers

Answer 1

Answer:

Must save 8 weeks or more to purchase the bike.

Step-by-step explanation:15*w >= 120 where W is the number of weeks.

w >= 120/15 = 8

Answer 2

You need to save $15 every week for the next 8 weeks in order to purchase the bike.

What is inequality in mathematics?

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Given is that you save $15 per week to purchase a bike that costs $120.

Assume that you need [w] weeks to save $120 for the bike.

Amount earned per week [A] = $15

Amount earned in [w] weeks [W] = $15w

Money needed [R] = $120

The inequality can be written as -

[W] ≥ [R]

We can write it as -

15w ≥ 120

Solving the inequality, we get -

15w/15 ≥ 120/15

w ≥ 8

Therefore, you need to save $15 every week for the next 8 weeks in order to purchase the bike.

Answers

Answer:

Step-by-step explanation:

The graph of a quadratic function is a U-shaped curve called a parabola. One important feature of the graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value. In either case, the vertex is a turning point on the graph. The graph is also symmetric with a vertical line drawn through the vertex, called the axis of symmetry. These features are illustrated in (Figure).

Graph of a parabola showing where the x and y intercepts, vertex, and axis of symmetry are.  

The y-intercept is the point at which the parabola crosses the y-axis. The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function, the values of x

( x, y ) = ( 4, 1/3)

Step-by-step explanation:

x - 3y = 3

2x +9y = 11

1. substitute the value of x

   x= 3 + 3y

   2x + 9y = 11

2. solve equation

   2 (3 + 3y) +9y = 11

3. substitute the value of y

  y = 1/3

4. solve equation

  x = 3 + 3 x 1/3

   x = 4

5. check solution

 (x, y)  = ( 4, 1/3 )

 check  x ---->  4 - 3 x 1/3 = 3

  check y ------> 2 x 4 + 9 x 1/3 = 11

If you spent 58 minutes doing English homework and 47 minutes doing math homework how much more time did you need to spend doing English homework?

Answer:

Step-by-step explanation:

Please brainliest me

There are 11 minutes more time to spend doing English homework.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

If you spent 58 minutes doing English homework and 47 minutes doing math homework.

Now,

Since, The time for doing English homework = 58 minutes

And, The time for doing Math homework = 47 minutes

So, The time more to spend doing English homework = 58 - 47

                                                                                   = 11 minutes

Thus, There are 11 minutes more time to spend doing English homework.

to find the vertex

x?+8y+2x - 23=0

Answers

Answer:

The vertex of the parabola is;

([-1], [3])

Step-by-step explanation:

The given quadratic equation is presented as follows;

x² + 8·y + 2·x - 23 = 0

The equation of the parabola in vertex form is presented as follows;

y = a·(x - h)² + k

Where;

(h, k) = The vertex of the parabola

Therefore, we have;

x² + 8·y + 2·x - 23 = 0

8·y = -x² - 2·x + 23

y = 1/8·(-x² - 2·x + 23)

y = -1/8·(x² + 2·x - 23)

y = -1/8·(x² + 2·x + 1 - 23 - 1) = -1/8·(x² + 2·x + 1 - 24)

y =  -1/8·((x + 1)² - 24) =  -1/8·(x + 1)² + 3

Therefore, the equation of the parabola in vertex form is y =  -1/8·(x + 1)² + 3

Comparing with y = a·(x - h)² + k, we have;

a = -1/8, h = -1, and k = 3

Therefore, the vertex of the parabola, (h, k) = (-1, 3).

Answers

Answer: Make the ramp longer

making the ramp shorter and making the ramp steeper would be the same, and backing up wouldn't really help

Pickle should make the ramp longer in order to be successful.

Option A is the correct answer.

What is a ramp?

The ramp refers to a sloped surface that connects a lower level to a higher level.

We have,

- A longer ramp will provide a more gradual slope, which will make it easier for the cart to move up the ramp.

- If the ramp is too short,

The slope will be too steep and it will be difficult to push the cart up.

- Making the ramp steeper will also make it more difficult to push the cart up.

- Starting with a running start may provide some initial momentum, but it will not address the underlying problem of the ramp being too short.

Thus,

Pickle should make the ramp longer in order to be successful.
