2x-2>8
2x>10
x = 10/2 = 5
x>5
since it is an absolute equation
it could also be x<-3
answer is x>5 or x<-3
1. To find the x-intercept, replace y in the equation with 0, then solve for x.
... To find the y-intercept, replace x in the equation with 0, then solve for y.
If the equation is easily put into the form
... x/a + y/b = 1
Then the x-intercept is "a" and the y-intercept is "b".
2. Let's graph 3x+4y = -12.
If we divide the equation by -12, we can put it into the form
.. x/(-4) + y/(-3) = 1
This equation has x-intercept -4 and y-intercept -3.
(If you know the intercepts, you can simply draw the line through them to graph your linear equation.)
35) that external angel is the 2 given angles added together (30 + 80 = dba)
36) same property (110 = 40 + x)
37) same property ( (x-20) + (3x-60) = 2x + 20)
40) I dont know either but I'm pretty sure that the type of angle that x is determines the triangle.
