What is the factorization??

aivan3 [116]

We first find the zeros of the function , the zeros of the function are those at which points the graph of the function crosses or touches the x axis

here we can see in the graph that graph crosses the x axis at two points , 1 and 7

So the zeros of the function are

x=1 and x=7

It means the factor are

(x-1) and (x-7)

So the factorization is given by

(x-1)(x-7)

3x^2+5x-12 solved by using quadratic formula

MArishka [77]

Answer:

$x = \dfrac{4}{3}$ or $x = -3$

Step-by-step explanation:

3x^2 + 5x - 12

To solve it, you need an equation, so I think you mean this equation.

3x^2 + 5x - 12 = 0

Using the quadratic formula, you have a = 3, b = 5, c = -12.

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

$x = \dfrac{-5 \pm \sqrt{5^2 - 4(3)(-12)}}{2(3)}$

$x = \dfrac{-5 \pm \sqrt{25 + 144}}{6}$

$x = \dfrac{-5 \pm \sqrt{169}}{6}$

$x = \dfrac{-5 \pm 13}{6}$

$x = \dfrac{8}{6}$ or $x = \dfrac{-18}{6}$

$x = \dfrac{4}{3}$ or $x = -3$

Which numbers are a distance of 7 units from 1 on a number line? Select the location on the number line to plot each point.

erma4kov [3.2K]

We need to find the numbers those are 4 units far from 1.

If we go to 7 units left side of 1 on number line we would add -7 to 1, we get

1-7 = -6.

And if we go to 7 units right side of 1, we would add +7 on 1 to get the number.

1+7 =8.

<h3>First we would plot a number 1 on number line.</h3><h3>Then we would go 7 units on the left side of 1 on number line, we would get -6.</h3><h3>Now, we would go 7 units right of the right side of 1 on the number line, we would get 8.</h3>

Find the slope of the line that passes through each pair of points

lyudmila [28]

Answer:

-1

Step-by-step explanation:

The slope of the line can be found by

m = (y2-y1)/(x2-x1)

= (-2-1)/(1--2)

=-3 /(1+2)

=-3/3

-1
