Write the equation of a line parallel to the line: y=-x-4 that goes through the point (-9,8)

Ymorist [56]

Answer:

y=-x-1 or, y-8=-1(x+9)

Step-by-step explanation:

Parallel lines have the same slope. in your current equation you have a slope of -1. We can use this slope and your set of points in the point slope formula.

y-y1=m(x-x1)

(-9, 8)

x1 y1 m=-1

y-8=-1(x+9)

y-8=-1x-9

+8 +8

y=-x-1

Determine whether quantities vary directly or inversely and find the constant of variation. It takes four identical water pumps

NNADVOKAT [17]

Let the number of water pumps be n and the time taken to fill the pool is t.

Now, we can see that higher the number of water pumps, lesser the time to fill the pool.

It means quantities vary indirectly.

Thus, $n=\frac{k}{t} , \text{ where k is the constant of variation}$

Now, we have been given that It takes four identical water pumps 6 hours to fill a pool.

Thus, we have

$4=\frac{k}{6} \\
\\
k=24$

Hence, constant of variation is 24.

Now, we have to find the time that three pumps will take to fill the same pool.

$3=\frac{24}{t} \\
\\
3y=24\\
\\
y=\frac{24}{3} \\
\\
y=8$

Hence, it will take 8 hours to fill the pool by three identical pumps.

Simplify: 3gh^2 x 4g^3h^3

katrin [286]

$\bf 3gh^2\times 4g^3h^3\implies 3\cdot 4\cdot g^1g^3h^2h^3\implies 12\cdot g^{1+3}h^{2+3}\implies 12g^4h^5$
