Answer:


Step-by-step explanation:

Is this graphing? If so, remember the formula: y=mx+b

If it's y=-1/3x+1, then 1 is your slope intercept

Place the dot on your graph where 1 is on your y-intercept.

Graphing -1/3x is just like rise over run, positives go up then right, (If 1/3 was graphed you would go 1 pixel up then 3 to the right.)

Since -1/3x is a negative, you're going down 1, left 3. It should give you a line that is coming from the top of the graphing box to the bottom.

If you want, create a table for x and y. If 0 was your x, then your y is 1, this is because theres a +1 in your equation.

If 3 was your x, then your y would be 0, because -1/3(3) + 1 is 0.

A container is being filled with water at a steady rate. The graph shows how the volume of water in the container varies with th
Mkey [24]

Answer:  a. v=\dfrac{2}{3}t and b. t=\dfrac{3}{2}v.

Step-by-step explanation:

Let as consider,

Volume (in gallons) of water in the container = v

The number of minutes = t

(a)

From the given graph it is clear that the line passing through the points (0,0) and (3,2). So, the equation of line is

v-v_1=\dfrac{v_2-v_1}{t_2-t_1}(t-t_1)

v-0=\dfrac{2-0}{3-0}(t-0)

v=\dfrac{2}{3}t

Therefore, the required formula is v=\dfrac{2}{3}t.

(b)

We have,

v=\dfrac{2}{3}t

Multiply both sides by 3/2.

v\times \dfrac{3}{2}=\dfrac{2}{3}t\times \dfrac{3}{2}

\dfrac{3}{2}v=t

t=\dfrac{3}{2}v

Therefore, the required formula is t=\dfrac{3}{2}v.

Please find the missing side and show your work:)
const2013 [10]

Answer:

The answer is 5.66

Step-by-step explanation:

let the missing side be x

9² = 7² + x²

9² - 7² = x²

x² = 9² - 7²

x² = 81 - 49

x² = 32

x = √32

x = 5.66
