How do i figure out from a already graphed graph what the equation

1 answer:

7 0

Put the equation in slope intercept form first. it’ll look somewhat like
y=mx+b (m is your slope and b is your y-intercept). you find your slope by drawing slope triangles. to draw a slope triangle, find two points and draw a triangle to connect them together. then you see how many it goes up/down and how many it goes to the side, left/right. the y-intercept is where the point crosses the y axis when x is 0.

Solve the following equation for h.<br> r+3Q/h=t

Arada [10]

Answer:

$\bold{h=\dfrac{3Q}{t-r}}$

Step-by-step explanation:

$\bold{r+\frac{3Q}h=t}\\-r\qquad\ -r\\\bold{\frac{3Q}h=t-r}\\\cdot h\qquad \cdot h\\ \bold{3Q=(t-r)h}\\^{\div(t-r)\quad\div(t-r)}\\\bold{\dfrac{3Q}{t-r}=h}$

Or, if you mean (r+3Q)/h=t:

$\bold{\frac{r+3Q}h=t}\\{}\ \ \cdot h\quad\ \cdot h\\\bold{r+3Q=ht}\\{}\ \ \div t\qquad \div t\\\bold{\dfrac{r+3Q}{t}=h}\\\\\bold{h=\dfrac{r+3Q}{t}}$
