Answer:

x = 1/3 or x = -2/3

Step-by-step explanation:

Let's solve your equation step-by-step.

9x2+3x−2=0

For this equation: a=9, b=3, c=-2

9x2+3x+−2=0

Step 1: Use quadratic formula with a=9, b=3, c=-2.

$x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

$x=\frac{-(3)\pm\sqrt{(3)^2-4(9)(-2)} }{2(9)}$

$x=\frac{-3\pm\sqrt{81} }{18}$

x = 1/3 or x = -2/3

In two or more complete sentences, compare the number of x-intercepts in the graph of f(t) = 12 to the number of x-

alina1380 [7]

Answer:

Both functions have one x-intercept each.

Step-by-step explanation:

The first function is

$f(t )= {t}^{2}$

This is a parabola with vertices at the origin and has one x-intercept at t=0.

The transformed function is

$g(t) = {(t + 3)}^{2}$

The function g(t) is obtained by shifting the graph of f(t) to the left by 3 units.

This graph also has one x-intercept at x=-3.

Therefore both functions has the same number of x-intercepts

Simplify: -10 - 90x + 6x - 60

antoniya [11.8K]

Answer:

- 84x - 70

Step-by-step explanation:

We want to combine like terms:

-10 - 90x + 6x - 60

We can see (-10) and (-60) are both regular constants so:

- 10 - 60 = - 70

Then (-90x) and (+ 6x):

6x - 90x = - 84x

- 84x - 70
