You can use the interactive graph below to find the solution. y = x - 4

y = 4x + 2

x = _

y = _

helppp
it then shows the graph shown in the picture!

x = -2

y = -6

Step-by-step explanation:

System of equations given in the question are,

y = x - 4 ---------(1)

y = 4x + 2 -------(2)

For equation (1)

y-intercept of the line → (0, -4)

x-intercept of the line → (4, 0)

Joining these points we can get the graph of the line represented by equation (1).

Similarly, for equation (2),

y - intercept of the line → (0, 2)

x- intercept of the line → (-0.5, 0)

Joining these points we will get the graph of the equation (2).

Solution of these equations will be the point of intersection or common points of both the equations.

From the graph attached,

Solution of the system of equations will be → x = -2

                                                                           y = -6

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
