A linear equation determines a line in the xy-plane.<br><br> A. True<br> B. False
Artemon [7]

Answer:

True, A linear equation determines a line in the xy-plane.

Step-by-step explanation:

A linear equation is in the form of Px + Qy = R where P , Q and R are constants.

Let us take an example 2x +3y = 6

When we plot the above equation in graph we get a line in xy plane.(as shown below) Since, there are two variables, x and y, then will it be possible, only on the xy plane.

It is also clear from the graph that linear equation shows the relation between x and y axis. Thus, it is true to say a  linear equation determines a line in the xy-plane.

A rectangular park, 90 meters by 60 meters, is to be built on a city block having an area of 9000 m^2. A uniform strip borders a
stealth61 [152]

Answer:

x = 10.52 m

Step-by-step explanation:

Given that,

Length of a park = 90 m

Width of a park = 60 m

Area, A = 9000 m²

A uniform strip borders all four sides of the park for parking. We need to find the width of the strip. Let it is x. Now the area becomes,

(90+2x)(60+2x) = 9000

4x^2 +120x +180x =5400 = 9000\\\\x=10.52\ m

So, the width of the strip is equal to 10.52 m.
