Because the zeros are -3 and 2, the factors are (x+3)(x-2)
expand it: x^2+3x-2x-6= x^2+x-6

Answer:

x^2+x-6[/tex]

Explanation:

We have been given two zeroes  x= -3 and x=2 of some quadratic equation

We have to find the quadratic equation when x=-3 is a zero means (x+3) is a factor and when x=2 is a zero means (x-2) is a factor

We have a formula to find the quadratic equation from zeroes is

x^2-(sum of zeroes )x+product of zeroes

Here sum of zero is -3+2=-1

And product of zero is (-3)(2)=-6

substituting the values in the formula we will get

x^2 -(-x)+(-6)=x^2+x-6

The slope-intercept form of an equation is y = mx + b. rewrite the equation in terms of the slope m
PSYCHO15rus [73]

Answer:

m=\frac{y-b}{x}

Step-by-step explanation:

So we have the equation:

y=mx+b

And we want to write it in terms of m.

So, let's subtract b from both sides:

y-b=mx

Now, let's divide both sides by x:

m=\frac{y-b}{x}

And we're done!

What is the slope the line that passes through the points:<br> (-6, 14), (2, -18)
Vesna [10]

Hey there! I'm happy to help!

Here's how to find the slope given any two points.

Subtract the y values.

14-(-18+-14+18=32

Subtract the x values.

-6-2=-8

And divide those.

32/-8=-4

The slope is -4.

Have a wonderful day! :D

The scale of a map is known to be 1: 500 000. Find the actual distance (in km) between a mall and the bus interchange if the rep
Evgen [1.6K]

Step-by-step explanation:

when the scale says 1:500000, then that means 1 unit in the map corresponds to 500000 units in reality.

and so, 3.2 cm on the map are

3.2 × 500000 cm in reality.

3.2 × 500000 = 1,600,000 cm = 16,000 m = 16 km

Rosa can clean a house in 7 hours. When Rosa and Amy work together, they can clean a house in about 4.2 hours. About how long wi
Step2247 [10]
First we will calculate rate of work of rosa and amy.
work done by rosa in time t=t*1/7
Work done by Amy and rosa=t(1/7+1/4.2)

t/7+t/a=t/4.2
t=10.5 hr

Always keep remember those formula or logic below

Work rate × Time to finish the job = 1 job done

Work rate = (1 job done) / (Time to finish the job)

Time of doing the job = (1 job done) / (Work rate)
