Answer: x= 41
Explanation: Angles 1 and 2 have to equal 180° since they are supplementary. So you put 3x+2x-25=180, you then add like terms. 5x-25=180 Then you have to isolate x, so you add 25 to both sides of the equation. 5x=205, then you divide both sides by 5. So your answer is x=41.
You can check to make sure by plugging in x for 41 .
Hope this helps!
Answer:
y-9=-4(x-2) or y=-4x-1
Step-by-step explanation:
First we must find the slope. Using the slope formula (diff y/diff x), we plug in using the given points;
(9-5)/(2-3)
=>4/-1 or just -4
Now, using the point slope formula, pick any point and plug into the formula y-y_1=m(x-x_1);
y-9=-4(x-2)
You can leave it just as this, if it asks specifically for slope-intercept form (y=mx+b) then just expand and simplify;
y-9=-4x+8
=> y=-4x-1
