Answer:

X=15

Step-by-step explanation:

Yes, you are right.

The given equation is

X+U=25

If U=10, then we substitute to obtain:

X+10=25

Subtract 10 from both sides to get:

X=25-10

Simplify to get:

X=15

HELPPPP ASPAPPPP PLEASEEEE !!!!!
Gnesinka [82]

Answer:

x^(1/3)

Step-by-step explanation:

let's start with x^2 / x^(2/3), then we'll move on the the 4th root

when dividing exponents with the same base, we subtract the exponents:

x^2 / x^(2/3) = x^(2 - 2/3) = x^(4/3)

the fourth root of x^4/3 can become x^(4/3 * 1/4)

(i used the formula x^(m/n) = nth root of x^m)

x^(4/3 * 1/4) = x^1/3

hope this helps! <3

What is the domain and range of the graph below in interval notation? If union is needed, use Capital U. If infinity is needed u
elena55 [62]

Answer:

DOMAIN: (-\infty,1]\cup(2,\infty)

RANGE: (-\infty,\infty)

Step-by-step explanation:

The domain of a graph is the span of x-values covered by the graph, while the range of a graph is the span of y-values covered by the graph.

DOMAIN:

From the graph, we can see that the x-values covers everything to the left of x=1. Then we stop and then continue beginning at x=2 all the way until positive infinity.

However, note that at x=1, the dot is a closed circle while at x=2, the dot is an open circle. Thus, we will include x=1 into our domain but not include x=2 into our domain.

So, our domain is all values greater than or less than 1, and all values greater than 2.

In interval notation, this is:

(-\infty,1]\cup(2,\infty)

We use brackets with the 1 because we include it in our domain and we use parentheses with the 2 since we do not.

RANGE:

Looking at the graph, it seems that all y-values are covered. The part of the graph on the left covers all y-values less than or equal to 3, while the part of the graph on the right covers all y-values greater than -1. Thus, all y-values are covered.

Our range is all real numbers.

In interval notation, this is:

(-\infty,\infty)

The area of a rectangle room is 750 square feet. The width of the room is 5 feet less than the length of the room. Which equatio
olga_2 [115]
By definition, the area of a rectangle is given by:
 A = (width) * (long)
 Substituting values we have:
 750 = (y-5) * (y)
 Rewriting we have:
 750 = y ^ 2 - 5y
 y ^ 2 - 5y - 750 = 0
 Answer:
 
An equation that can be used to solve for And the length of the room is:
 
y ^ 2 - 5y - 750 = 0
