Answer:

C:protractor

Step-by-step explanation:

A compass is needed to draw arcs that are used to determine the position of the perpendicular bisector

A pencil works hand in hand with the compass

A straightedge is used to draw straight line that will be the bisector.

Note that a protractor is used to measure angles and not to construct angles.

X-4y=-17 and y=4x +8 solve by graphing please and show the solution
nikitadnepr [17]

Answer:

The answer to your question is (-1, 4) The lines cross in one point so they have only one solution.

Step-by-step explanation:

Data

Equation 1     x - 4y = -17

Equation 2    y = 4x + 8

Solve for y

Equation 1          y = -x/-4 - 17/-4

                          y = x/4 + 17/4

Equation 2         y = 4x + 8

See the graph below

These lines cross in point (-1, 4), so that is the only one solution.

If the lines were the same line they would have infinite solutions
