I'm given 10=log(x) and i'm supposed to find the x-intercept.
do i do (10^10)=x or do i change 10 to 0?

  x = 10^10

Step-by-step explanation:

You are right to question the question. As posed, it makes no sense.

The idea of an x-intercept is applicable to a relation involving two variables that can be graphed on a coordinate plane.

If you graph this equation on an x-y plane, it will be a vertical line at x = 10^10, so that would be the x-intercept.

I suggest you ask for an explanation from your teacher.

The graph of y=log(x) is something else entirely, as you know. The x-intercept of that graph is x=1.

7

step-by-step explanation:

the answer would be 7

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.
