What are the roots of the equation?

2 answers:

7 0

For the equation to = 0 , one of the components must = 0
x = 0
x = -13/9
x = -2/11

(Make each bracket = 0)
e.g. 9x+13=0
9x = -13
x = -13/9

A turtle can walk 1/12 of a kilometer in an hour. The turtle is 1/5 of a kilometer away from a pond. At this speed how long will

Cloud [144]

Answer:

2.4 hours

Step-by-step explanation:

Get common denominators -

1/12 x 5/5 = 5/60

1/5 x 12/12 = 12/60

The turtle walks ata 5/60 a kilometer an hour.

divide remaining time by 5/60

(12/60) / (5/60) = 2.4 hours

What is the x-intercept of the equation 3x - 2y = -12

muminat

X=2/3y-4

EXPLANATION
3x-2y=-12
You take -2y to the other side
It becomes 3x=2y-12
Then you divide 3
X=2/3y
-12/3=-4
X=2/3y-4

Write your answer with no space and any fraction with “/“

nirvana33 [79]

Answer:

y+3=2(x-1)

Step-by-step explanation:

Point-slope form is $y-y_1 = m (x-x_1)$ . In order to write a linear equation using this form, the $y_1$ , $x_1$ and $m$ must be substituted by real numbers.

The $m$ represents the slope of the equation. We know that the answer has to be parallel to the line y=2x-1. y=2x-1 is already in slope-intercept form, or $y=mx+b$ , in which $m$ represents the slope. We can see that the $2$ is in place of that $m$ , therefore 2 is the slope of y=2x-1. Lines that are parallel have the same slope, so we know that the slope of the new equation must be 2 as well.

The $x_1$ and $y_1$ represent the x and y values of one point that the line passes through. We know that the new equation must pass through the point (1, -3), so we'll substitute 1 in place of the $x_1$ and -3 in place of the $y_1$ .

Substituting for those three values will give you an equation like this, therefore it is the answer:

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

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