Can someone help me with these Algebra II problems?
1) is this written coreectly? As it is it is unsolveable. start by dividing by 3 > x^2 = -27 then get square root --however there is no square root of a negative number 2) multiply both sides by 6 > 5q^2 - 2q^2 = 432 simplify q terms > 3q^2 = 432 divide both sides by 3 > q^2 = 144 find sq root > q = 12 3) start by getting the x terms on the same side and putting the number terms on the other 5x/12 - x/6 = -1/2 - 1/4 multiply by 12 to get rid of denominators 5x - 2x = -6 - 3 simplify 3x = -9 divide by 3 x = -3 hope that helps :)

The timeline shows the approximate total area of glaciers on Mount Kilimanjaro from 1970 to 2000. YEAR 1970 1980 1990 2000 --------------------------------------... AREA 5.2 km 4.1 km 3.0km 1.9km a. Make a table that shows the number of years x since 1970 and the area of the glaciers y (in square kilometers). b.Graph the data in the table. Explain how you know the area of glaciers changed at a constant rate. c.Write an equation that models the area of glaciers as a function of the number of years since 1970. By how much did the area of the glaciers decrease each year from 1970 to 2000? I don't get it. .____. Please help me? :)

The superhero’s height is given by:[math]f(x) = -16x^2 + 200x[/math]From this, we note that he is starting on the ground. Also, we will ignore the superhero’s own height.Suppose we want to know whether his height can ever be 612 ft high.We set his height function equal to 612 and then see if we can solve it. We will use a discriminant to check what kind of solutions it has.[math]612 = -16x^2 + 200x[/math][math]-16x^2 + 200x - 612 = 0[/math][math]-4x^2 + 50x - 153 = 0[/math]The discriminant of this polynomial is [math]50^2 - 4*(-4)(153) = 4948[/math]. Because this discriminant is positive, this polynomial has two real solutions. This means the expression, at some time [math]x[/math], [math]f(x) = 612 ft[/math].Note:The question does not ask for the specific time when [math]f(x) = 612[/math].It asks a yes-no question, and asks you to explain.Using a discriminant, you can say—for certain—whether his height reaches 612 ft. without knowing when it happens.However, some teachers may expect a graph or even a solution.Going a step further:If one were using calculus, you can find when the superhero reaches his maximum height.For a function [math]f(x)[/math], the maximum or minimum value is obtained when [math]f’(x) = 0[/math].Where [math]f(x) = -16x^2 + 200x[/math], then[math]f' = -32x + 200[/math][math]0 = -32x + 200[/math][math]x = 200/32 = 6.25[/math]So, the maximum height is attained after 6.25 seconds.That height is [math]f(6.25) = -16(6.25)^2 + 200(6.25) = 625 ft.[/math]Because the maximum value is 625 ft., the superhero can clear a building that is 612 ft.I only include this last part to stoke your curiosity.
Could someone please help me with this Algebra 1 story problem?
I'm having some trouble with my Algebra 1 homework, and I thought maybe someone could help me on Yahoo Answers. The story problem that I don't understand goes like this: A town committee has a budget of $75 to spend on snacks for the volunteers participating in a clean-up day. The committee chairperson decides to purchase granola bars and at least 50 bottles of water. Granola vars cost $0.50 each, and bottles of water cost $0.75 each. Write and graph a system of linear equalities for the number of bottles of water and the number of granola bars that can be purchased. (It says to graph, but I can do that if I have the system of inequalities)
Can someone help me with this algebra exercise ?
If we interpret your question as finding a set of vectors that are a basis of the plane: [math] 2x + y - 3z = 0[/math] let’s note that the plane is a two dimensional space in three-space. Accordingly, spanning the space requires only two independent vectors in the plane.(1, 1, 1) lies in the plane as does (0, 3, 1). So those two vectors form a basis.vectors of the form (2, 0, 0) do not satisfy the equation for the plane and hence cannot be part of the basis.

Can someone help me with these Algebra I word problems? show work 1. At 7:00 am Joe starts jogging at 6 mi/h. At 7:10 am Ken starts off after him. How fast must Ken run in order to overtake him at 7:30 am? 2. It takes a plane 40 min. longer to fly from Boston to LA at 525 mi/h than it does to return at 600 mi/h. how far apart are the cities? 3. It took Cindy 2 h to bike from Abbott to Benson at a constant speed. The return trip took only 1.5 h because she increased her speed by 6 km/h. How far apart are Abbott and Benson? thanks
Can you help me with these math problems? [algebra 1]?
1) 12x^3 - 18x² + 27x first factor out the common factor: 3x = 3x(4x² - 6x + 9) for the trinomial to factor, we would need factors of 36 (9x4) that add to 6, and they don't exist. So that is your final answer. #2) 1 - 10r + 25r² rewrite: 25r² - 10r + 1 This is a perfect square: (5r - 1)(5r - 1) or (5r - 1)² #3) also a perfect square: (2y + 3)² #4) you need factors of 8x99 that subtract to give you 2. list some factors: 24x33, 12x66, 36x22, 18x44, 11x72 ... You can see that we can't get the difference to be 2, so the trinomial is prime, meaning it can't be factored. that's it! ;)
