Answer:
No. of x-intercepts is equal to the no. of distinct species factors of a polynomial
Since this curve has only one distinct factor i.e (x+7)
The only x-intercepts is -7
(-7,0)
Y intercept would be at (0+7)⁷
Which is (0,7⁷)
Or (0,823543)
Since it's an odd power, branch of the curve for x > 7 would approach positive infinity
Branch for x < 7 would approach negative infinity
first you convert to slope intercept form
3x+y = 5 is the same as y = -3x+5
x - 4y = 32 is the same as y = 4x-8
then you graph
(starting with the y-intercepts as your first points)
the point where the two lines intercept is your solution.
(a) I'd say sometimes true. 3 + -7= -4 , -5 + 3= -2 , 8+-5=3, 7+-7=0
(b) I'm not too sure about this one but I what i know is that if the positive number is higher than the negative number it will be a positive. If you are adding both a negative number and a positive number that is the same value it will be 0. And if you are adding a negative that is higher than the positive it will be a negative number.
I hope this helped a bit.. (:
