Determine the inverse
A matric is of the form:
First, we need to calculate the determinant (D)
By comparison, we have:
The inverse is then represented as:
This gives:
Answer:
22 m/s
Step-by-step explanation:
We know the car travels 374 m in 17 seconds, so to find out how far it travels in 1 second, divide 374 m by 17 seconds:
unit rate in m/s = 374 m / 17 s = 22 m/s
Answer:
should be 42

Determine the domain and the range
The domain and range of a function is represented as thus (x,y)
From the given parameters;
Remove "Grade" to represent as only digits
Split to x and y values:
<em>Where x = domain and y = range</em>
<em>So, from the list of given options; option C answers the question.</em>
Pat = p, Zach = z
p = 6 + 2z... 2z = p - 6... z = (p-6)/2
p + z < 36
(6 + 2z) + z < 36
3z + 6 < 36
2z < 30
z < 15
So the greatest age for z Zach that is less than 15 is 14!
