How is this college algebra..? seems like grade 6 stuff to me lol Anyways...the y intercept is +6 and the x intercept is 3/2 To find y intercept...you must make the x value to 0... therefore y=-4(0) +6 y= +6 To find x intercept you must make the y value to 0... 0=-4(x)+6 -6/-4...

Is this really college algebra? However, suppose you take a car and assign it the value x, for instance, beacuse of it being the xth car you encounter on the street. Suppose you've looked up any setting of its. It is called y (u), where the (u) shall denote the unit of the ...

And yes this is College Algebra...some of us are better at things other than math. I'm doing great after being graduated for 17 years, a 9 year old, a husband and a full time job. I'm loving my A average thank you.

Since you called it "College Algebra" I will assume you know Calculus. h'(t) = -32t + 272 b) max height obtained when -32t+272 = 0 t = 8.5 seconds a) h(2.5) = -16(8.5)^2 + 272(8.5) = 1156 c) to strike ground, h(t) = 0 -16t^2 + 272t = 0 -16t(t - 17) = 0 t = 0, (at the start) or...

college algebra--Please help Reiny please
You helped me with this question and this is what I got but my Professor says that each x and y intercept needs to have a coordinate. Where did I go wrong?? Can you help me? x^2+y^2+4x+2y-20=0 x^2+4x+4+y^2-2y+1=20+4+1 (x+2)^2+(y+1)^2=25--this is where you helped me. Then I ...

college algebra--Please help Reiny please
What you did is correct, but it would have been easier to do it this way: let y = 0 (x+2)^2 + 1 = 25 (x+2)^2 = 24 x + 2 = ± √24 = ± 2√6 x = -2 ± 2√6 same way for the y-intercept so the x-intercepts are: (-2+2√6 , 0) and (-2 - 2√6, 0) the y-...

a) by the "just look at it" theorem slope = 5, y-intercept is 3 b) can't graph on here c) average rate of change = slope = 5 d) the slope is positive, so the function is increasing college algebra ?? mmmhh.
