Determine the solutuon for x^2-3x-28>0

natita [175]

Answer:

x < -4 or x > 7.

Step-by-step explanation:

We first determine the critical points by solving x^2 - 3x - 28 = 0:

x^2 - 3x - 28 = 0

(x - 7)(x + 4) = 0

x = 7, - 4

so the critical points are -4 and 7.

Create a Table (pos = positive and neg = negative):

Value of x< - 4 -4 < x < 7 x > 7

---------------------|----------- |--------------------- |---------------------

x + 4 NEG POS POS

x - 7 NEG NEG POS

(x + 4)(x - 7) POS NEG POS

So the function is positive (>0) for x < -4 or x > 7.

You can also do this by drawing the graph of the function.

How many solutions does this linear have y= 5x-1 -15x-3y=3?

musickatia [10]

-15x - 3y = 3

-15x - 3(5x-1) = 3 [input y]
-15x - 15x - 3 = 3 [distribute 3 over 5x and -1]
-30x - 3 = 3 [combine like terms]
-30x = 6 [add 3 to eliminate the negative]
x = $\frac{6}{-30}$ [divide by -30 to get x alone]
x = $\frac{1}{-5}$ [reduce the fraction]

Hopefully this is helpful enough to get you to your answer
