So you multiply 4 times 3 to find a common denominator 12 then you multiply 1 times 3 and 2 times 4 to get 1/4 = 3/12 and 2/3 = 8/12

Hey! please help me with this question
astraxan [27]
The answer is 1/4 or 0.25.

steps:
first look in the parenthesis and notice that the denominator is not the same. set the denominator to 6 for the fraction 1/3 by multiplying 3(2) and 1(2) which makes the fraction 1/6. now add -5/6 and 1/6 inside the parenthesis. you should get -3/6 which you should put in the simplest form: -1/2. now combine -1/2 and -1/2 to get 1/4

(Sketch the graph x^2-7x+12=0​
Nonamiya [84]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

x^{2} -7x+12=0

This is a vertical parabola open upward (because the leading coefficient is positive)

The vertex is a minimum

step 1

Find the vertex of the quadratic equation

Convert the equation in vertex form

Complete the squares

(x^{2} -7x+3.5^2)+12-3.5^2=0

(x^{2} -7x+12.25)+12-12.25=0

(x^{2} -7x+12.25)-0.25=0

Rewrite as perfect squares

(x-3.5)^{2}-0.25=0

The vertex is the point (3.5,0.25)

step 2

Find the x-intercepts

The x-intercepts are the values of x when the value of the function is equal to zero

we have

(x-3.5)^{2}-0.25=0

solve for x

(x-3.5)^{2}=0.25

square root both sides

(x-3.5)=\pm0.50

x=3.5\pm0.50

x=3.5+0.50=4

x=3.5-0.50=3

therefore

The x-intercepts are the points (3,0) and (4,0)

step 3

Find the y-intercept

The y-intercept is the value of y when the value of x is equal to zero

we have

y=x^{2} -7x+12

For x=0

y=(0)^{2} -7(0)+12

y=12

The y-intercept is the point (0,12)

step 4

Graph the quadratic equation

we have

The vertex (3.5,0.25)

The x-intercepts (3,0) and (4,0)

The y-intercept  (0,12)

using a graphing tool

Plot the points and draw the figure
