Answer 2

Answer:

Step-by-step explanation:

For a graph to be a function, there must not be more than one element in the range for each element of the domain.

If x represents the doman, and y represents the range (as usual, in graphing) then each value on the the x-axis should not have more than one point in the graph on it, directly above it, or directly below it. Like if you had a point (5, 7) and also had point (5, -7), that is not a function. The x, 5, has more than one y-value  paired with it.

Visually, any vertical line through the graph should not intersect the graph at more than one point. If it does, then the graph is not a function.

This is called the vertical line test.

Answers

Answer:

5(n+1)/((n+1)(n+3))

5/(n+3) is a answer

Step-by-step explanation:

(n+1)/(n+1)=1

The solution is, the simplified product of the expression 5/n+1*n+1/n+3 is 5/(n+3) .

here, we have,

given that,

the expression is  5/n+1*n+1/n+3

now, we have to find the  simplified product.

as, * means the multiplication,

we get,

5/n+1*n+1/n+3

=5*(n+1)/((n+1)*(n+3))

now, we know that,

(n+1)/(n+1)=1

so, we get,

5*(n+1)/((n+1)*(n+3))

=5*1 /(n+3) *1

=5/(n+3) is a answer

Answer:

p + 10

Step-by-step explanation:

We have an expression

"10 more than the number p"

How will you write the phrase?

The expression "10 more than the number p" shows that whatever amount p is, the total will always be 10 more of value than p. Therefore some type of adding is supposed to be here. Since this unknown value of a number will always be 10 more than p, we can come up to assume that p will be added by 10.

p + 10

Answer:

x + 21 + 33 = 180

An isosceles triangle has a perimeter of 28.12 centimeters. The length of the longest side is 13.08 centimeters. What could be the length of
one of the other sides of the triangle?
A. 3.92 centimeters
B. 7.52 centimeters
C. 11.26 centimeters
D. 15.04 centimeters

Answers

Answer:

7.52 cm

Step-by-step explanation:

If we subtract the longest side from the whole perimeter, we get 28.12 - 13.08 = 15.04.

So the other two sides must be equal, since the triangle is isosceles.

That means 15.04 must be divided evenly betweem two sides.

15.04/2 = 7.52

So the 3 sides are 13.08 cm, 7.52 cm, and 7.52 cm.

You check the answer by adding all 3 sides together and we do indeed get the perimeter, 28.12 cm.

Answer: x=15

Step-by-step explanation:

Since these are supplementary angles, we know that if we add them together we would get 180 deg. so....

(7x-10)+ (6x-5)=180

Kay so now we can combine like terms.

13x-15=180

Now we can add 15 to both sides.

13x=195

Finally Divide 13 on both sides.

X would then now equal 15.
