Answer: X=43
Explanation.
1. x-7/9=4
2. x-7=4x9
3. x-7= 36
4. X=36-7
5. X=43
14 I think.You would subtract 15-8 which is 7 and then add 7 which is 14
Answer:
A and D are not polynomials. B and C are polynomials
Step-by-step explanation:
In order to find out what function is a polynomial, you have to understand what a polynomial is. A polynomial is a sum of monomials that make up a polynomial expression. A mononomial is a real number, with a variable, and a exponent of a variable that makes up one term. For example 
is a monomial. It has a real number, a variable, and a exponent that makes up one term. A polynomial has one or more monomial terms that make it a polynomial. So firstly, a polynomial by definition cannot have a negative exponent. That eliminates D. Why? because by definition, the standard form of a polynomial function states that n cannot be positive, it has to be a nonnegative integer. Also, polynomials can only be real numbers. It cannot have a nonreal number. Radical forms without a perfect square are nonreal numbers. So that eliminates A. However, B and C can be polynomials because the definition of polynomials say that real numbers, nonnegative exponents, and constants can be part of a polynomial function. Even with the fraction, that would be part of rational expressions (polynomial/polynomial), which is polynomials. I hope this helps friend. Math can be tough to explain just as much as doing it :)
Answer:
Two lines only can intersect if the lines are not parallel.
And given a linear equation:
y = a*x + b
Where a is the slope and b is the y-intercept, the general equation for a parallel line to this one is:
y = a*x + c
with the condition:
b ≠ c
So we need to have the same slope and a different y-intercept.
Then when we compare the linear function that represents the number of animals adopted with the linear function that represents the hours volunteers work at the shelter, you need to look if both equations have a different slope or not.
Let's describe the two cases:
If the lines have the same slope, then you need to see the y-intercept.
If the y-intercept is different, then the lines never do intersect.
If the y-intercept is equal, then both equations describe the same line (as both have the same slope and the same y-intercept).
If the lines have different slope, then we can conclude that the lines are not parallel, and the lines will intersect at some point.
Answer:
The coefficient of squared term is 1/9
Step-by-step explanation:
The vertex of parabola is (2.-3)
We know the vertex form of a standard parabola
Plugging values of h and k, h= 2, k = -3
Now, x=5, y=-2
Thus, the coefficient of squared term is 1/9
