How to graph -x + 2y = 6

1 answer:

3 0

In order to graph the equation, you need some coordinates,
So, put x = 0,
2y = 6. y = 3. Coordinate = (0, 3)

Now, put y = 0,
-x = 6
x = -6 Coordinate (-6, 0)

In short, Just mark that two points and draw a line, graph is done

Hope this helps!

In right triangle ∆ABC, ∠A = 42°. Find the measure of ∠B which is the other non right angle.

Zigmanuir [339]

Answer:

48 degrees

Step-by-step explanation:

A triangle has three angles that add up to 180 degrees. In a right triangle, one of the angles in 90 degress, and the other 2 add up to 90. In this case, we have 2 given angles, 90 degree angle and 42 degree angle. If we do 90+42 it gives us 132. We then subtract that from 180 to give us 48 degrees.

Sindrei [870]

Answer:

Step-by-step explanation:

Part A:

3x^2 -2x -1 + 9x + 2x^2-3 = 5x^2 + 7x -4

Part B

5x^3 + 4x^2 -x-3 -(5x^2 +7x-4) = 5x^3 -x^2-8x+1

Part C:

They do show polynomials are closed for addition and subtraction because both resulted in another polynomial

Answer the question to get points

geniusboy [140]

Answer:

4. E=4x-15(vertically opposite)

F=E(corresponding angles)

E=4x-15

5.3x+6x+O=180(angles on a straight line)

9x+0=180

9x=180-0

9x/9=180/9

x=20
