What is the solution of 3x + 5 = 2x – 7?
a. the x-coordinate of the intersection point of the lines y = 3x + 5 and y = 2x – 7
b. the x-coordinates of the x-intercepts of the lines y = 3x + 5 and y = 2x – 7
c. the y-coordinate of the intersection point of the lines y = 3x + 5 and y = 2x – 7
d. the y-coordinates of the y-intercepts of the lines y = 3x + 5 and y = 2x – 7

Option: A is correct.

A.  The x-coordinate of the intersection point of the lines y = 3x + 5 and y = 2x – 7

Step-by-step explanation:

We are asked to find the solution of the equation:

3 x+5=2 x-7.

We can also equate these equation to y so that:

y=3 x+5=2 x-7

i.e. we plot the equation:

y=3 x+5

and y=2 x-7

and see the intersection point and the solution will be the x-value of the coordinate of the intersection point.

The solution is:

x= -12.

As the equation is in a single variable 'x' hence the solution of the equation is the value of x.

Hence, the solution of 3x + 5 = 2x – 7 is:

(A. the x-coordinate of the intersection point of the lines y = 3x + 5 and y = 2x – 7 )

Option: A is correct.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
