Rewrite! Write an new and equivalent equation that is easier to solve

RUDIKE [14]

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - an equation in it's general form

To do - convert the given equation into a form that is easy to solve

Given equation -

$\bold{(x + 2) {}^{2} + 4(x + 2) - 5 = 0} \\$

solve the parenthesis so as to obtain simpler terms

$\bold{\implies \: ( x {}^{2} + 4x + 4 ) + 4x + 8 - 5 = 0}\\$

solve the like terms and you'll obtain the required equation !

$\bold{\implies \: x {}^{2} + 8x - 7 = 0}$

Charles can do a job in 1 hour, bill can do the same job in 2 hours, and bob can do the job in 3 hours. How long does it take th

KiRa [710]

Charles can do the whole job in an hour, Bill can do 1/2 of the job in an hour, and Bob does 1/3 of the job in an hour. Therefore, they do a total of 1+1/2+1/3=11/6 of the job in an hour, meaning it takes them 6/11 of an hour. This is 6/11*60=360/11 minutes, or approximately 33 minutes.

Pauty went to the shopping mall at 11:30 A.M.

natka813 [3]

It’s 12:35, if you add 40+25 it equals 65, 60 minutes is an hour, subtract 65-60 and you’ll get 5. The hour brings you to 12:30 and then you add the remaining time (5 minutes), which will give you 12:35.

Find the slope of the following ^ :)) |

Luba_88 [7]

Answer:

m [slope] = 0

Step-by-step explanation:

When the slope is 0, x cancels out so the y value will remain the same.

There are several methods to finding slope but the easiest way to do this is by dividing the second y value - first y value by the second x value - first x value.

m = ∆y/∆x = y2-y1/x2-x1

You y2 and x2 are interchangable with y and x, because y1, and x1 are part of the starting coordinate,.

The reason you subtract the second

value from the first is because in a directly proportional relationship, y increases as x increases so the next x values will have a greater y value, this is a measure of steepness.

So the slope is:

-1 - -1 / 3 - -2 = -1 + 1 / 3 + 2 = 0 / 5 = 0.
