Conversions aren't bad until you have to deal with the cubed and squared versions of them!! Remember that there are 100 cm in 1 meter. If that be the case, then there are 100cm*100cm*100cm (100cm^3) in m*m*m (1 meter cubed). We will use that in our conversion then: $250,000 \frac{cm^3}{m^2}* \frac{m*m*m}{100cm*100cm*100cm}$ . The cm^3 cancels out leaving m^3 over m^2 which is what we want. Doing the math now we get $.25 \frac{m^3}{m^2}$ , or $\frac{1}{4} \frac{m^3}{m^2}$

The point-slope form of the equation of the line that passes through (–5, –1) and (10, –7) is y plus 7 equals negative StartFrac

user100 [1]

Answer:

2x + 5y = - 15

Step-by-step explanation:

The line that passes through (–5, –1) and (10, –7) points and the point-slope form of the equation is $y + 7 = - \frac{2}{5}(x - 10)$ .

Now, we have to arrange this in the standard form.

So, $y + 7 = - \frac{2}{5}(x - 10)$

⇒ 5(y + 7) = - 2(x - 10)

⇒ 5y + 35 = - 2x + 20

⇒ 2x + 5y = - 15 (Answer)

What is the equatipn of the linear graph?<br> (-4, 6).<br> (1, -9)

dusya [7]

Answer:

y = -3x - 6

Step-by-step explanation:

first, find the slope

(-4, 6)

(1, -9)

remember the equation for the slope

$\frac{y_{2}-y_{1}}{x_{2} - x_{1}} }$

insert given points

$x_{1} = -4\\y_{1} = 6\\\\x_{2} = 1\\y_{2} = -9$

((-9) - (6)) / ((1) - (-4))

simplify

( -9 - 6) / (1 + 4)

= -15/ 5

= -3

now insert it into the equation of the line

remember, the equation of the line is

y = mx + b

where "m" is the slope

and "b" is the y-intercept

to find "b", you just have to plug in a point that is found on the line

we know that (-4, 6) and (1. -9) is found on the line, so let's just use (-4, 6) for this problem

y = mx + b

substitute in the slope of this line

y = -3x + b

now substitute in the given points

6 = -3 * -4 + b

and solve it like any algebra problem, by inverse operations and simplifying

6 = 12 + b

-12 -12

-6 = b

so the equation of the line is

y = -3x -6

Susan and terry run a day care center Since they use susans house it was agreed that her share is twice as Terrys if they earn 2

Nadya [2.5K]

The easiest way to do this is to divide 225 by 3, so 225 / 3, and what you get as the sum, in this case it's 75, you would multiply the sum by 2, which equals 150, and that, would be Susan's share. So... 225 / 3 = 75. 75 * 2 = 150. $150 is the amount Susan gets. Hope this helps!

-6h plus 4 - 3plus h equals 11

olga55 [171]

$- 6h + 4 - 3 + h = 11$
So we start by combining like terms;
$- 6h + h = - 5h$
$4 - 3 = 1$
Now we have;
$- 5h + 1 = 11$
We then subtract 1 from both sides;
$- 5h + 1 = 11$
$- 5h = 10$
Then we divide both sides by 5;
$- 5h = 10$
$- 5h \div - 5h = h$
$10 \div - 5h = - 2$
Leaving the final answer to be h = -2
