Answer:

Option C - (0,1), (-5/2,6)

Step-by-step explanation:

Given : The system of equations y=2x^2+3x+1 and y=-2x+1

To find : Solve the system by graphing ?

Solution :

Let the equation 1 - y=2x^2+3x+1  is a quadratic equation.

Equation 2 - y=-2x+1 is a linear equation.

Plot these equation in the graphing tool,

Equation 1 y=2x^2+3x+1  is shown by blue line with vertex (-0.75,-0.125).

Equation 2  y=-2x+1  is shown by green line passing through (0.5,0) and (0,1).

The intersection point of the equations is the solution of the system i.e. (-2.5,6) and (0,1).

The solution is (0,1), (-5/2,6).

Refer the attached figure below.

Therefore, Option C is correct.

if i I wanted to be precise, how can I express the exact circumference for the circumference given the diameter
sveticcg [70]
The formula for circumference is \pi d.

To express the circumference exactly, plug the diameter in for d and put the \pi symbol in front of it. Don't multiply. This expresses the exact circumference.

Say you have the diameter of 17.
You can express the circumference with 17\pi.

Need help finding a constant k at which the function is continuous everywhere.
saveliy_v [14]

Answer:

k = -6/35

Step-by-step explanation:

To make the function continuous

kx^2 = x+k

These must be equal where the function is defined for two different intervals

This is at the point x=-6  so let x=-6

k(-6)^2 = -6+k

36k = -6+k

Subtract k from each side

36k-k = -6+k-k

35k = -6

Divide by 35

35k/35 = -6/35

k = -6/35
