Step-by-step explanation:

Since it is asking for a perpendicular line, we take the reciprocal of the slope in the given equation to use as the slope for the perpendicular line.

In y = x + 2, m = 1. However, for a perpendicular line we flip and multiply by a negative 1.

(Example: If m = 3, we would take the reciprocal of it and it turns into m = -1/3. If m = - 1/4, we would take the reciprocal of it and it turns into m = 4.)

So, the m = 1 turns into a m = -1.

Now, you can use the point (4,-1) to form a point-slope equation first.

y-(-1) = -1(x-4)

Then, use basic algebra to form a slope-intercept form equation.

y + 1 = -x + 4

y = -x +3

Let a=3/4 and b=1/5. If a*x=b, then what is x?
Anarel [89]

In general, any equation like ax=b (assuming a \neq 0) is solved by

x= \dfrac{b}{a}

So, in your case, the solution is

x = \dfrac{\frac{1}{5}}{\frac{3}{4}}

Dividing by a fraction means to multiply by the inverse of that fraction:

\dfrac{\frac{1}{5}}{\frac{3}{4}} = \dfrac{1}{5} \cdot \dfrac{4}{3} = \dfrac{4}{15}

Volume question
ioda

Answer:

The answer is 61.4 L

Step-by-step explanation:

Using the formula of cuboid, V = l×b×h, to find the total amount of water contained :

l = 120cm

b = 40cm

h = 15cm

V = 15×120×40

= 72 000cm³

= 72 L

It is given that she uses 10.6L for shower. Then calculate the remaining water by substracting 10.6L from the original amount of water :

remaining = 72 - 10.6

= 61.4 L
