Which system of equations does this graph represent?

System of the equations will be y = x + 4 and y = x² + 2

Step-by-step explanation:

The system of equations comprises a parabola and a straight line.

We will form the equation of the line first.

Straight line given in the system passes through two points (2, 6) and (-1, 3).

Since standard for of a straight line is given by y = mx + c

where m = slope and c = y-intercept

So, Slope m =

m =  

m = 1

And y-intercept c = 4

Therefore, equation of the line will be y = x + 4

For the equation of parabola.

Vertex form of the parabola is represented by,

y = (x - h)² + k

Where (h, k) is the vertex.

Vertex is given in the graph is (0, 2).

So the equation will be y = (x - 0)² + 2

y = x² + 2

Therefore, system of the equations will be y = x + 4 and y = x² + 2

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
