7 0

Answer:

3x - 2

Step-by-step explanation:

4x + 2 -  \frac{ {x}^{2}  + x - 12}{x - 3}  \\  \\  = 4x + 2 -  \frac{ {x}^{2}  + 4x  - 3x- 12}{x - 3}  \\  \\  =  4x + 2 -  \frac{ {x}(x  + 4)  - 3(x  + 4)}{x - 3}  \\  \\  = 4x + 2 -  \frac{ (x  + 4)   \cancel{(x- 3)}}{\cancel{(x- 3)}}  \\  \\  = 4x + 2 - (x + 4) \\  \\  = 4x + 2 - x - 4 \\  \\  = 4x - x + 2 - 4 \\  \\  = 3x - 2

Question 1 of 10<br> (x)=x2. What is g(x)?<br> y<br> f(x)<br> g(x)<br> -5<br> 6<br> (3, 3)<br> 5
never [62]

The graph is attached and the answer to the function g(x) = (1/3)x²

Option A is the right answer.

<h3>What is a Function ?</h3>

A function is a mathematical statement that relates a dependent variable and an independent variable.

It is given that

f(x) = x²

It has been asked to determine the equation of g(x)

It can be seen from the graph the the vertex is same just the graph is scaled.

The point (3,3) is of g(x) , when the value of y at at x =3 is 9

Therefore the scale factor is 1/3

And we can do trial and error on the basis of the options given ,

The graph is attached and the answer to the function g(x) = (1/3)x²

Option A is the right answer.

Find a numerical value if one trigonometric function of x if tan2x-sin2x/sin2x=5
seropon [69]

Answer:

The values of x that satisfy the given equation are:

x1 = 1.183 + nπ

x2 = -1.183 + nπ

Step-by-step explanation:

Given tan²x - sin²x/sin²x = 5

Simplifying this, we have

tan²x - 1 = 5

Adding 1 to both sides, we have

tan²x = 6

Because tan²x = (tanx)², we can write as

(tanx)² = 6

Taking square roots of both sides, we have.

tanx = ±√6

x = arctan(±√6) + nπ

≈ 1.183 + nπ or -1.183 + nπ

9. Evaluate 14(-6x +10) - 16x - 100x + 140 for x = -2.
Radda [10]

Answer:

680

Step-by-step explanation:

14(-6x +10) - 16x - 100x + 140 for x = -2.

14(-6(-2) + 10) - 16(-2) - 100(-2) + 140

14(12 + 10) + 32 + 200 + 140

14(22) + 372

308 + 372

Hazel has an assortment of red, blue, and green balls. The number of red balls is the number of blue balls. The number of green
dem82 [27]

Answer:

Step-by-step explanation:

We are given that Hazel has an assortment of red , blue and green balls.

The number of red balls=The number of red balls

The number of green balls is more than the number of blue balls .

Let number of blue balls=x, Number of red balls=y, Number of green balls =z

Let total number of balls=w

Then number of red balls,y= Number of blue balls=x

According to question

x=y

z>x

The total number of balls,w= sum of all balls

w=x+y+z

w=x+x+z

w=2x+z

substitute x<z

w>2x+x

w>3x

Both side divided by 3 then we get

\frac{w}{3}>x

x.

Hazel will have number of blue  balls is given by the equation

x.

Where x= Number of blue balls

w=Total number of blue balls.
