Answer: see last picture

Step-by-step explanation:

We see that the y-intercept is 10 and the slope is -3

so when x = 0, y = 10

Graph this first point (picture 1)

Since the slope is -3, every time you go one unit to the left, you go down 3 units, so graph this second point (picture 2)

Continue this until you have no more room on the graph (picture 3)

now draw a line through the dots (picture 4)

6x^2-9x +2=0 solve the quadratic equation using the quadratic formula

balu736 [363]

ANSWER:

The roots of $6 x^{2}-9 x+2=0$ are $\frac{9+\sqrt{33}}{4}, \frac{9-\sqrt{33}}{4}$

SOLUTION:

Given, quadratic equation is $6 x^{2}-9 x+2=0$ --- eqn (1)

We need to find the roots of given quadratic equation using quadratic formula.

Quadratic formula for general quadratic equation $a x^{2}+b x+c=0$ is $X=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

Here, for eqn (1) a = 6, b= -9 and c = 2

$X=\frac{-(-9) \pm \sqrt{(-9)^{2}-4 \times6 \times 2}}{2 x 2}$

$X=\frac{9 \pm \sqrt{81-48}}{4}$

$\begin{array}{l}{X=\frac{9 \pm \sqrt{33}}{4}} \\ {X=\frac{9+\sqrt{33}}{4}, \frac{9-\sqrt{33}}{4}}\end{array}$

Hence the roots of $6 x^{2}-9 x+2=0$ are $\frac{9+\sqrt{33}}{4}, \frac{9-\sqrt{33}}{4}$

If f(x) = 3x^2- 1 and g(x) = 4x + 2, then what is g(f(x))?

katrin2010 [14]

Answer:

g(f(x) = 12x^2-2

Step-by-step explanation:

solution:

given,

f(x)=3x^2-1

g(x)=4x+2

g(f(x)=?

here,

g(f(x) = g(3x^2-1) [put the value of f(x) given]

=4(3x^2-1)+2 [ now put the value of g(x) and in the place of x put 3x^2-1]

=12x^2-4+2 [ by multiplying 4(3x^2-1) ]

= 12x^2-2 ans..

So g(f(x)=12x^2-2

hope its helps , I tried my best to explain there

hope you understand it as i am terrible at explaining like this ...

have a good time(•‿•)
