NEED HELP. WILL MARK BRAINLIST. DO NOT SPAM

Tcecarenko [31]

Answer:

a) x = {-2, 1, 3} are the zeros

b) y = (x +2)(x -1)(x -3)

c) y = x^3 -2x^2 -5x +6

Step-by-step explanation:

a) The zeros are the values of x where the graph crosses y=0. Those values are x = -2, x = 1, x = 3.

b) If "a" is a zero, then (x-a) is a factor. The factored polynomial is ...

y = (x +2)(x -1)(x -3)

c) This can be multiplied out using the distributive property several times.

y = (x +2)(x(x -3) -1(x -3))

= (x +2)(x^2 -3x -x +3)

= (x +2)(x^2 -4x +3)

= x(x^2 -4x +3) +2(x^2 -4x +3)

= x^3 -4x^2 +3x +2x^2 -8x +6

y = x^3 -2x^2 -5x +6

_____

The supplied graph apparently scales this vertically by a factor of 1/2, since its y-intercept is at (0, 3), not (0, 6).

a line passes through (9, –9) and (10, –5).write an equation for the line in point-slope form. rewrite the equation in standard

Cerrena [4.2K]

The equation of the line in point-slope form is given by:
$y-yo = m (x-xo)
$
Where,
(xo, yo): point that belongs to the line
m: slope of the line
The slope is given by:
$m = \frac{y2-y1}{x2-x1}$
Substituting values:
$m = \frac{-5-(-9)}{10-9}$
Rewriting:
$m = \frac{-5+9}{10-9}$
$m = \frac{4}{1}$
$m=4$
Now we choose an ordered pair:
$(xo, yo) = (10, -5)
$
Substituting values we have:
$y-(-5)=4(x-10)$
$y+5=4(x-10)$
We now rewrite the equation in its standard form:
$y = mx + b
$
Where,
b: cut with the y axis.
We have then:
$y = 4x - 40 - 5

y = 4x - 45$
Answer:
point-slope form:
$y+5=4(x-10)$
or
$y+9=4(x-9)$
standard form
$y = 4x- 45$

1/3=7/21, .. What are the means

gayaneshka [121]

Answer:

Equivelant fractions.

Step-by-step explanation:

Ask your self..

How did the 1/3 become 7/21?

Its very simple multiply 1/3's numerator and denominator by 7

So its going to be.. 1 x 7 = 7

3 x 7 = 21

Therefore, we have 7/21
