Find all the zeros of x^3-5x^2-x+5

Mathematics
1 answer:
AnnyKZ [126]3 years ago
3 0
The fact that the coefficients are pairwise identical (except for sign) tells you that x^2 -1 is a factor (and x-5 is the other factor). Of course, you recognize x^2-1 as a special form (the difference of squares) that is factored as (x +1)(x -1).

The zeros are x = -1, +1, +5.

___
A graphing calculator confirms this.

musickatia [10]

Answer:

F=95\°

Step-by-step explanation:

we know that

C=\frac{5}{9}(F\°-32)

In this problem we have

C=35\°

substitute the given value in the formula and solve for F

35\°=\frac{5}{9}(F\°-32)

F-32=\frac{9}{5}(35)

F=\frac{9}{5}(35)+32

F=95\°

Rewrite in simplest terms: 9(-9f-2)-9(5f+10)
Deffense [45]

Answer:-126f-108

Step-by-step explanation:

9(-9f - 2)-9(5f +10)

-81f - 18 -9(5f + 10)

- 81f - 18 - 45f -90

- 126f - 18 - 90

-126f -108

which give you the answer -126f - 108

Simple math but I can't seem to understand it: x+y=2 becomes y=2-x, in order to find slope and y intercept y=mx+b The result bec
IgorLugansk [536]

Answer:

See below.

Step-by-step explanation:

So we started off with the equation:

x+y=2

And we subtracted x from both sides to acquire:

y=2-x

Now, this is essentially slope-intercept form. Recall that the slope-intercept form is:

y=mx+b

Where m is the slope and b is the y-intercept.

If we rearrange our equation:

y=2-x\\y=-x+2

And put some parentheses:

y=(-1)x+(2)

We can see that this is indeed slope-intercept form.

And we can see that m is -1 and b is 2.

In other words, the slope is -1 and the y-intercept is 2.

The slope of y= 1/2x-7
Arisa [49]
The slope of y= 1/2x-7 is always positive because since the slope of this equation is “1/2”, 1/2 is always positive.
