Answer:

Mr. Sato needs 9 more magnets.

Step-by-step explanation:

The 24 students will form 12 pairs. The total number of magnets needed is 12*3 = 36. Mr. Sato  gave out 9*3=27 magnets already and so he will need 36 - 27 = 9 more magnets.

Answer:

  C. x^2 + 3

Step-by-step explanation:

Substitute for f(x) and g(x) and simplify.

  (f -g)(x) = f(x) -g(x)

  (f -g)(x) = (2x^2 +2) -(x^2 -1) = 2x^2 +2 -x^2 +1

  (f -g)(x) = x^2 +3

sesenic [268]

The expression      5 = \sqrt{(x-6^2)+(y - 5)^2}  can be used to find the coordinate of Point B. Option C is correct.

Given that,
Segment AB has point A located at (6, 5). If the distance from A to B is 5 units, which of the following could be used to calculate the coordinates for point B is to be determined.

<h3>What is the equation?</h3>

The equation is the relationship between variables and represented as y = ax +c is an example of a polynomial equation.

Let the coordinates of B be (x, y)
Now the distance between A (6, 5) and B (x, y) is c = 5 units
So, by the distance formula, the distance between two points is given as,


C = \sqrt{(x_1-x_2)^2 +(y_1-y_2)^2}


now put the value in the formula.

5 = \sqrt{(x-6^2)+(y - 5)^2}

Thus, expression      5 = \sqrt{(x-6^2)+(y - 5)^2}  can be used to find the coordinate of Point B. Option C is correct.

For each equation give X a value and solve for Y, do this at least two times for each equation.

Plot those dots on a graph to draw two lines.

The solution is where the two lines cross.

You will see the lines cross at (-1,-2)
