5e-8

Explanation: 2.9 x 10^5 x 7.2 x 10^2 = 208800000

5 x 10^-8 = 5e-8

I am so sorry if I am incorrect, but here the answer I got.

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
$y = 4x- 45$

anygoal [31]

<span>the numbers of first 8 beads which are white are 1,5,9,13,17,21,25,29 think of it as an arithmetic progression here the first term will be 1 cause white was first bead then after 3 blue beads another white added soits position is fifth now the difference would come out as 5-1=4 so now position of next white bead could be predicted by nth term formula of an AP which a+(n-1)d here a is first term which in this case is one and d is difference which here is 4 So nth bead position is 1+(n-1)4</span>

What is the answer y= x-3

Komok [63]

Answer:

Step-by-step explanation:

If you’re wanting the yes or no answer, keep reading.

If you’re wanting a number for y and x, we can’t give that to you. It’s infinite!

Since both y and x = 0, the equation would be set up as 0 = 0-3. You can see the equation is false, so it would be a no.
