Factorize the polynomial: 6q^2 – q – 12.

Ksivusya [100]

Answer:

Step-by-step explanation:

What two number multiply to equal 6*(-12) and add to equal -1? That is -9 and +8.

$6q^2-9q+8q-12$

Now factor by grouping

$(6q^2-9q)+(8q-12)\\3q(2q-3)+4(2q-3)\\(3q+4)(2q-3)$

The range of which function is (2, infinity)? y = 2x y = 2(5x) y = 5x +2 y = 5x + 2

Sveta_85 [38]

Answer:

I think your functions are $y=2^{x}$ , $y=2*5^{x}$ and $y=2+5^{x}$

If yes then then the third function which is $y=2+5^{x}$ .

Step-by-step explanation:

The function $c^{x}$ where c is a constant has

Domain : $c\geq 0$

Range : ( 0 , ∞ )

The above range is irrespective of the value of c.

I have attached the graph of each of the function, you can look at it for visualization.

<em> $y=2^{x}$ ⇒ </em>This function is same as $c^{x}$ so its range is <em>( 0 , ∞ )</em>.

<em> $y=2*5^{x}$ ⇒ </em>If we double each value of the function $y=5^{x}$ , which has range ( 0 , ∞ ), but still the value of extremes won't change as 0*2=0 and ∞*2=∞. Therefore the range remains as <em>( 0 , ∞ )</em>.

<em> $y=2+5^{x}$ </em> ⇒ If we add 2 to each value of the function $y=5^{x}$ , which has range ( 0 , ∞ ), the lower limit will change as 0+2=2 but the upper limit will be same as ∞. Therefore the range will become as <em>( 2 , ∞ )</em>.

What is the equation of the line that passes through<br> (-2, 4) and (2, 7)?

shepuryov [24]

Answer:

$y=\frac{3}{4}x+\frac{11}{2}$

Step-by-step explanation:

Hi there!

We want to find the equation of the line that passes through (-2, 4) and (2, 7).

The most common way to write the equation of the line is in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept.

First, let's find the slope of the line.

The slope, calculated from two points is given as the formula $\frac{y_2-y_1}{x_2-x_1}$ , where $(x_1, y_1)$ and $(x_2, y_2)$ are points.

We have two points, which is needed to find the slope, but let's label their values to avoid confusion.

$x_1=-2\\y_1=4\\x_2=2\\y_2=7$

Now substitute those values into the formula.

m= $\frac{y_2-y_1}{x_2-x_1}$

m= $\frac{7-4}{2--2}$

Simplify

m= $\frac{7-4}{2+2}$

m= $\frac{3}{4}$

So the slope of the line is $\frac{3}{4}$ .

Substitute that value as m in y=mx+b

y= $\frac{3}{4}x+b$

Now we need to find b

As the equation passes through both (-2, 4) and (2, 7), we can substitute the values of either one of them in the equation to solve for b

Taking (-2, 4) for example,

Substitute -2 as x and 4 as y:

4= $\frac{3}{4}(-2)+b$

Multiply

4= $-\frac{3}{2}$ +b

Add -3/2 to both sides

$\frac{11}{2} = b$

Substitute that value into the equation

y= $\frac{3}{4}x+\frac{11}{2}$

Hope this helps!
