Solve the equation using the zero product property -2x(5x-2)=0

Mathematics
1 answer:
anastassius [24]3 years ago
5 0

Answer:

A

Step-by-step explanation:

Given

- 2x(5x - 2) = 0

Equate each factor to zero and solve for x

- 2x = 0 ⇒ x = 0

5x - 2 = 0 ⇒ 5x = 2 ⇒ x = \frac{2}{5}

Solutions are

x = 0, x = \frac{2}{5}

What is the slope of the function
uranmaximum [27]

The slope of this line is 1/2.

In order to find the slope of any equation, you can take two points and use the slope formula. For ease, we'll use the two intercepts that you can see: (0, -3) and (6, 0). The formula for slope is below.

m = (y2 - y1)/(x2 - x1)

In this equation, m is the slope and (x1, y1) is the first ordered pair and (x2, y2) is the second. So we place those values in to solve for m.

m = (y2 - y1)/(x2 - x1)

m = (0 - -3)/(6 - 0)

m = 3/6

m = 1/2

And that is your slope.

Answer:

y = -3 (you have to draw an horizontal line that passes for the point (0,-3)

Step-by-step explanation:

We have to find the middle points of the segments that unite the corrispettive points.

We are lucky because the images of the points have the same x coordinate of the original ones, so we have just to find the y coordinates.

Segment CC‘

(y1 + y2)/2 = (-1-5)/2 = -3

Segment AA’

(0-6)/2 = -3

Segmet BB’

(1-7)/2 = -3

Segment DD’

(1-7)/2 = -3

In conclusion we can say that the points of the reflection have all the y coordinate equal to -3.

the line is horizontal and its equation is : y = -3

A pump can fill a swimming pool in 8 hours. The pool also has a drain that can empty the pool in 10 hours. If someone turns on t
cluponka [151]

Answer:

40 hours will it take for the pool to fill.

Step-by-step explanation:

A pump can fill a swimming pool in 8 hours.

Work done by pump to fill in 1 hour is  \frac{1}{8}

The pool also has a drain that can empty the pool in 10 hours.

Work done by pump to drain in 1 hour is  \frac{1}{10}

If someone turns on the pump to fill the pool, but forgets to shut the drain.

Work done by both pipe in 1 hour is

W=\frac{1}{8}-\frac{1}{10}

W=\frac{10-8}{80}

W=\frac{2}{80}

W=\frac{1}{40}

Both pipe filled \frac{1}{40} part of pool in hours = 1

Both pipe filled complete pool in hours = \frac{1}{\frac{1}{40}}=40

Therefore, 40 hours will it take for the pool to fill.
