Mathematics

never [62]3 years ago
8 0

Answer: option C.

Step-by-step explanation:

Given  a quadratic function of the form ax^2+bx+c, if the coefficient <em>a</em> is less than zero, then the function is opened upward.

The options A is not opened upwards, then it is not the answer.

Then the given equation x^2+2=6 can be written as:

x^2+2-6=0\\x^2-4=0

This function is equal to the parent function, shifted 4 units down.

Therefore, the graph that you are looking for must be a parabola that is opened upwards and has its vertex in the point (0,-4).

Then, the correct option is C. And the solution is:

x=-2\\x=2

Subtracting by adding up 65-39
rjkz [21]

Answer:

<h2>26</h2>

Step-by-step explanation:

In order to subtract by adding up 65-39, we need to add -39 to the value of 65. This can be rewritten in this way;

65+(-39)

The equation above is similar to the one given because the product of a minus and a plus sign will still give us back a minus sign.

on solving;

65+(-39) = 26

Answer:

The correct answer is A. A fairly strong positive correlation

Step-by-step explanation:

Scatter Plot : A graph of plotted points that show the relationship between two sets of data.

Now, the points of the scatter plot are going up this shows the increase in the data points so we can say the correlation is positive.

Now, the direction of the scatter plots is to the right. So, we can say that the correlation is strong correlation.
