Refer attached figure.
Step-by-step explanation:
Given: Two strings 15 inches long and 7 inches long.
We have to draw a diagram for a problem about finding the total length for two strings,15 inches long 7 inches long.
Consider the two strings 15 inches long and 7 inches long.
Consider two strings AB and BC with measure 15 inches and 7 inches long
To find the total length join one end of a string with one end of other string (as shown in figure)
Thus, 15 + 7 = 22 string

Step-by-step explanation:
Think about it.
What two numbers multiply to -15 and add up to 2?
The answers are 5 and -3.
So plug that into the factored form of a parabola.
To find the x-intercepts, plug in 0 for .
Since we are multiplying, at least one of the terms has to equal 0.
So the x-intercepts are and
.

Step-by-step explanation:
The domain of a function is the set of values of the independent variable that the function can take according to given rules or restrictions.
The range is the set of values the dependent variable can take for every possible value of the domain.
The graph shows a continuous line representing the values of the function. We must take a careful look to the values of x (horizontal axis) where the function exists. It can be done by drawing an imaginary vertical line passing through the value of x. If that line touches the graph of the function, it belongs to the domain. It's clear that every value of x between -5 and 3 (both inclusive because there are solid dots in the extremes) belong to the domain:
Domain:
The range is obtained in a similar way as the domain, but the imaginary lines must be horizontal. That gives us the values of y range from -7 to 5 both inclusive:
Range:
Thus we disagree with Zach and Delia and agree with Alicia
