Answer:

The system has infinitely solutions

Step-by-step explanation:

we have

-\frac{1}{3}x^{2}=-\frac{5}{6}+\frac{1}{3}y^{2}

\frac{1}{3}x^{2}+\frac{1}{3}y^{2}=\frac{5}{6}

Multiply by 3 both sides

x^{2}+y^{2}=\frac{5}{2} ----> equation A

The equation A is a circle centered at origin with radius r=\sqrt{5/2}\ units

and

5y^{2} =\frac{25}{2}-5x^{2}

5x^{2}+5y^{2} =\frac{25}{2}

Divide by 5 both sides

x^{2}+y^{2} =\frac{5}{2} ----> equation B

The equation B is a circle centered at origin with radius r=\sqrt{5/2}\ units

Equation A and Equation B are the same

Therefore

The system has infinitely solutions

What is the area of the triangle?<br>PLSSS help me
AveGali [126]

Answer:

The area of the triangle is A=6 \:units^2.

Step-by-step explanation:

The area <em>A</em> of a triangle is given by the formula A=\frac{1}{2} bh where <em>b</em> is the base and <em>h</em> is the height of the triangle.

From the graph, we can see that the base is 3 units and the height is 4 units. Therefore, the area of the triangle is

A=\frac{1}{2} \cdot3\cdot 4=\frac{12}{2}=6 \:units^2

What is the sum of -7 and 3? <br> A. -4 <br> B. -3 <br> C. 3 <br> D. 4
lions [1.4K]

Answer:

-4

Step-by-step explanation:

Using a number line can help solve this problem

-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 1

To add a positive number to a negative one, we are going to move that number of spaces to the right (We are adding positive 3 to negative 7, so we are moving 3 spaces to the right)

-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 1

               ^ We start here at negative 7

-10 -9 -8 <em>-7</em><em> </em>-6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 1

                   ^    ^   ^  Then move three to the right

-10 -9 -8 -7 -6 -5 <u>-4</u> -3 -2 -1 0 1 2 3 4 5 6 7 8 9 1

So -4 is our answer
