Answer:

The equation is,

$(x+1)^{2} \times (x+2) = 0$

Step-by-step explanation:

According to the question, the equation is cubic and have roots -1 (with multiplicity of 2) and -2.

So, the equation is,

$(x+1)^{2} \times (x+2) = 0$

[Since, when a , b , c are the roots of a cubic equation, the equation is

given by $(x-a) \times (x-b) \times (x-c) = 0$ ]

Given the function below, find /(-7)<br> (X) = -2x-1

Lostsunrise [7]

For this case we have a function of the form $y = f (x)$ where:

$f (x) = - 2x-1$

We must find the value of the function when $x = -7$ . So:

$f (-7) = - 2 (-7) -1$

By definition we have to:

$- * - = +\\f (-7) = 14-1 = 13$

Thus, the value of the function is $y = 13$

Answer:

$y = f (-7) = 13$

A student bought 5 coats at $86 each and paid for them with only $20 bills. How many bills did it take ?

aleksandr82 [10.1K]

It took 22 $20 bills . $86 x5= $430
Then $430 divide by 20 = 21.5
So you can’t have half a bill do the answer has to be rounded up to 22 twenty dollar bills
