• ### Given 2x - 3y = 9 and 5x - 2y = -16, how to solve for x and y?

Best answer: 2x - 3y = 9
5x - 2y = -16
4x - 6y = 18
15x - 6y = -48
11x = -66
x = -6, y = -7
Best answer: 2x - 3y = 9
5x - 2y = -16
4x - 6y = 18
15x - 6y = -48
11x = -66
x = -6, y = -7

But school teaches you skills you will use in a job. Many (but not all) jobs use algebra. You will never need. to do a chemistry equation or dissect a frog or recite the Magna Carta or analyze a Shakespeare poem at home in everyday life. But you will need to get some kind of job someday where some skills are required.

• ### Help me sketch this graph pls: 2x-y=-4?

Best answer: There are many ways to go. One way is to solve for the intercepts. Solve for x when y = 0 and solve for y when x = 0. That will give you two points. Then connect the points and you have your line: 2x - y = -4 2(0) - y = -4 and 2x - 0 = -4 0 - y = -4 and 2x = -4 -y = -4 and x = -2 y = 4 and x = -2 So your... show more

2x - y = -4
2(0) - y = -4 and 2x - 0 = -4
0 - y = -4 and 2x = -4
-y = -4 and x = -2
y = 4 and x = -2

(0, 4) and (-2, 0)

Plot the points and connect the points.

• ### I was told to solve this: (2x^2 + 3)^2 = 4x(x^3 + 6)?

Best answer: Expand out both sides: (2x² + 3)(2x² + 3) = 4x(x^3) + 4x*6 4x^4 + 12x² + 9 = 4x^4 + 24x Cancel 4x^4 from both sides: 12x² + 9 = 24x Get everything on the left: 12x² - 24x + 9 = 0 To simplify, divide both sides by 3: 4x² - 8x + 3 = 0 Factor that: (2x - 3)(2x - 1) = 0 Two solutions: 2x - 3 = 0 2x = 3 x =... show more
Best answer: Expand out both sides:
(2x² + 3)(2x² + 3) = 4x(x^3) + 4x*6
4x^4 + 12x² + 9 = 4x^4 + 24x

Cancel 4x^4 from both sides:
12x² + 9 = 24x

Get everything on the left:
12x² - 24x + 9 = 0

To simplify, divide both sides by 3:
4x² - 8x + 3 = 0

Factor that:
(2x - 3)(2x - 1) = 0

Two solutions:
2x - 3 = 0
2x = 3
x = 3/2
or
2x - 1 = 0
2x = 1
x = 1/2

x = 1/2 or x = 3/2
