There are six poles on a side of a 1 km 200 m long straight road such that there is a pole at the starting and end points of the

Bingel [31]

Answer:

Distance is 200m between each pole

Step-by-step explanation:

First, convert the length of the road into meters

1km= 1000m

1000m +200m= 1200m

There are 6 poles on the side and they're equally spaced

Divide the length of the road by the number of poles to get the distance between the poles

Distance between poles= Length of road/ Number of poles

Distance between poles= 1200m/ 6 poles

Distance between poles= 200m

Please help solve -2|5y-1|=-10

sweet-ann [11.9K]

Alright, so we can start by dividing -2 from both sides, getting |5y-1|=20. Then, since 5y-1 is in an absolute value, 5y-1 is either 20 or -20.
In 5y-1=20, we can add one to both sides, getting 5y=21 and y=21/5. In
5y-1=-20, we can add one again, getting 5y=-19 and y=-19/5.

If you have any more equations, make sure to plug both numbers in to check, but otherwise y has two answers , which are -19/5 and 21/5.

Which set of points includes all of the solutions for y = 5/2x + 3/2?

Firdavs [7]

Answer:

Choice A: $(x,\frac{5}{2}x+ \frac{3}{2} )$ . for all real numbers.

Step-by-step explanation:

We are looking for points on the x-y plane which satisfy the equation y = 5/2x + 3/2, and these point are all those that lie on the graph of the equation, which are points $(x,y) = (x,\frac{5}{2}x+ \frac{3}{2} )$ .

Looking at the other choices we see that choice B gives only 3 points, and regardless of whether they lie on the graph of y or not, this choice cannot be correct because 3 points are not all solutions.

The same goes for choice D.

And choice C is just the whole of x-y plane, therefore this cannot be the answer because not every point on the x-y plane is a solution to y = 5/2x + 3/2
