Step-by-step explanation:
42.8 in
Step-by-step explanation:
Step one:
given data
we are told that the expression for the depth of a lake after x years is given by
Required
The value of y when x= 4
Step two:
substitute the value of x in the expression to get y
After 4 years the depth will increase by 42.8 in

➷ We can assume that the roles will be filled in order
To calculate this, figure out the number of possible candidates for each role
For role 1, there are 9 possible candidates
For role 2, there are 8 possible candidates
For role 3, there are 7 possible candidates
For role 4, there are 6 possible candidates
For role 5, there are 5 possible candidates
Simply multiply all these values together:
9 x 8 x 7 x 6 x 5 = 15120
Therefore, your answer would be B. 15,120

Answer:
B - the graph of the function does not form a straight line
Step-by-step explanation:
linear functions have to form a straight line, and that function in the question is a quadratic because x is to the power of 2.
<span>2x+3y=11
Y= -2x + 1 re-write -2x - y = -1
so
</span>2x + 3y =11
-2x - y = -1
--------------add
2y = 10
y = 5
<span>Y= -2x + 1
</span>5 = -2x + 1
-2x = 4
x = -2
answer
solution (-2 ,5)
