Answer:
x=45
Step-by-step explanation:
Since AB is a straight line, it is 180 degrees
AOE + EOF + FOD + DOB = 180
15+x+2x+120-2x = 180
Combine like terms
135 +x = 180
Subtract 135 from each side
135-135 +x = 180 -135
x = 45
0.24 is an even number....so 2 will be a factor
2x = 0.24
x = 0.24 / 2
x = 0.12
so 2 factors would be 2 and 0.12.....because 2 * 0.12 = 0.24
Hard to tell what the value of base is.
Area is 39.69
A=1/2 • base• height
The easy way to find the y-intercept is to write the equation is slope intercept form as:
y = mx + c
The c will be the y-intercept.
The given equation is:
7x - 2y = 1
Re-arranging we get:
2y = 7x - 1
Divide both sides by 2, we get;
y = 7/2 x - 1/2
Compare this to the top most equation, you get the y-intercept to be -1/2
At y-intercept, the x coordinate is 0. So the ordered pair will be (0, -1/2)
So basically you can determine which of them are functions by using the vertical line test. If you can draw any vertical line that intersects more than one point of the relationship, then it is not a function.
I'm not complete sure about the discrete one but, hopefully it's right :).
