Answer: \\ 2x + 3y = 12 \: \vee \: 30x + 11y = 112 \\\Leftrightarrow 30x + 45y = 180 \: (1)\: \vee \:30x + 11y = 112 \: (2) \\ (1) - (2)\Rightarrow 34y = 68\Rightarrow y = 2 \\ 2x  + 3 \times 2 = 12\Rightarrow x = 3

Answer:

Slope intercept form is y=mx+b. M= -1, which means your slope is -1. So far the equation is y=-x+b. Now you need to find b which is the y-intercept. To find b, you will use the point (1,3). You will plug it in into the equation, it will look like this 3=-1(1)+b. Now you solve for b. Multiply -1 and 1 you get -1. Add 1 to both sides and you have b=4. So the equation is y=-x+4. So to find k, plug in the point (k,6). It will look like this 6=-k+4. Subtract 4 on both sides. 2=-k is what you have so far. Divide by -1 on both sides. THE ANSWER IS K=-2.

Help. Pic attached. I do not understand how to get the numbers.
Dima020 [189]

Answer:

If they are same side interior or same side exterior they will always add up to 180 so if you have m<7 = 131 then you subtract 131-180 and then you have the angle for one and you do it so on and so forth. If you have A corresponding angle, alternate exterior,alternate interior or a vertical angle they will be the same number at the angle given.
