What is the solution to the system of equations graphed below y=1/2x+2 y=-2x+-3
vladimir1956 [14]

Answer:

<h2>x = -2, y = 1</h2>

Step-by-step explanation:

given the system of equations y=1/2x+2 and y=-2x+-3, since the 2 equations are functions of y, we will equate both equations together and calculate the value of x as shown

1/2x+2 = -2x-3

x/2+2x = -3-2

5x/2 = -5

5x = -10

x = -10/5

x = -2

Substituting x = -2 into any of the equation to get the value of y we have;

y = -2(-2)-3

y = 4-3

y = 1

The solution to the system of equation (x, y) = (-2, 1)

The degree measure of angle a is 135°. which expression below is equivalent to the radian measure of angle a?
Kazeer [188]

It is given that \angle a=135^{\circ}.

Now, know that in 180 degrees there are \pi radians. This can be written as:

180^{\circ}=\pi radians

\therefore 1^{\circ}=\frac{\pi}{180} radians (dividing both sides by 180)

Thus, to find the measure of the given angle of 135^{\circ} in radians, we will have to multiply the above equation by 135. Thus, we get:

135^{\circ}=\frac{\pi}{180}\times 135 radians

135^{\circ}\approx2.356 radians

Thus, equivalent to the radian measure of angle a is 2.356
