Answer:
15x - y = - 6.....15x + 6 = y...so we sub in 15x + 6 in for y on the other equation
5x - 3y = -13
5x - 3(15x + 6) = -13 <== the new equation
Step-by-step explanation:
Answer: If two pair is parallel then it has no solution.
Step-by-step explanation:
Since we have given that
Let the number of gained yards by each player be y
For the case of Brayden:
Equation will be

For the case of Howard :
Equation will be

For the case of Vincent :

Since First two equations are parallel so it has no solution.
Reason:

Hence, if two pair is parallel then it has no solution.
For a the answer is: 48 km/hr. For b the answer is: The distance could be longer, so if she took hours she would have to drive faster; or if starter distance she would have driven slower
Answer:
, x ≠ -1/4
Explanation:We are given that:
f (x) = 4x + 1
g(x) = x² - 5
We want to find the value of (g/f)(x). This means that we will simply divide g(x) by f(x) as follows:

Now, we should note that any function is undefined if its denominator is equal to zero.
This means that for our current function:
4x + 1 cannot be equal to zero
4x + 1 = 0
4x = -1
x = -1/4
This means that the value of x cannot be -1/4, otherwise, our function would be undefined.
Based on the above, the last option is the correct one.
Hope this helps :)
