Can someone explain to me multi step algebra equations? 15 points Thaaaanks~
aalyn [17]
So take 4x-2x=4                                                                                                        first combine like terms so now u have 2x=4.          now you will isolate the x to find what it equals. divide 2 from both sides so u have x=2.                                      did this help any?

Kareem cuts 12 identical circles of pastry form a 30cm by 40cm sheet. Find the area of pastry {which remains}
ch4aika [34]
<h3>Exact Area = 1200 - 300pi   square cm</h3><h3>Approximate Area = 257.522203923062 square cm</h3>

Work Shown:

The area of the rectangle is 40*30 = 1200 square cm

Note how we have 4 circles along the horizontal dimension which is 40 cm, so each diameter is 40/4 = 10 cm, and the radius is 10/2 = 5 cm

Each circle has an area of pi*r^2 = pi*5^2 = 25pi

There are 4*3 = 12 circles, so the circle areas combine to 12*25pi = 300pi

Using a calculator, we find that 1200 - 300pi = 257.522203923062 approximately. Round this however you need to.

With unique examples of your own let’s discuss the number of solutions possible (0, 1, 2, 3, 4) to a system of equations that in
chubhunter [2.5K]

The number of solutions possible to a system of equations that include a conic section depends on the type of equations involved

<h3>How to determine the number of solutions?</h3>

A system of equation that has a conic section may or may not have solutions.

It would have a solution if the equations intersect, when plotted on a graph and it would not, if otherwise

A conic section can be any of:

  • Parabola
  • Ellipse
  • Hyperbola
  • Circle

<u>Example 1: No solution</u>

Consider the following system of equations

  • y = x² - 10 --- parabola equation
  • (x - 1)² + (y - 2)² = 5 --- circle

The above system of equations has no solution because they do not intersect when plotted on a graph (see graph 1)

<u>Example 2: One solution</u>

Consider the following system of equations

  • x = 2 --- linear equation
  • y = x² - 10 --- parabola

The above system of equations has one solution because they intersect at one point (see graph 2)

<u>Example 3: One solution</u>

Consider the following system of equations

  • y = 2x + 1 --- linear equation
  • y = x² - 10 --- circle

The above system of equations has two solutions because they intersect at two points (see graph 3)

The above examples imply that a system of equations that involves conic section can have as many solutions as possible.

The number of solutions depends on the type of equations involved

The attached graphs illustrate how a system of equations can have 0 to 4 solutions
