Answer:
D
Step-by-step explanation:
Using the midpoint formula to find the coordinates of Q
let the coordinates of Q = (x, y ), then
0.5(3 + x) = 2 ← equate to x- coordinate of M
Multiply both sides by 2
3 + x = 4 ( subtract 3 from both sides )
x = 1
and
0.5(9 + y) = 8 ← equate to y- coordinate of M
Multiply both sides by 2
9 + y = 16 ( subtract 9 from both sides )
y = 7
Thus the coordinates of Q are (1, 7 ) → D
<span>y= -2/3 - 5x
or
</span>y= -5x -2/3
so
slope = -5
Answer:
f(-3)=5x^2+5x*3
-f*3=5x^2+5*3x
-3f=5x^2+15x
f=-5x(x+3)/3
f(-9)=5x^2+5x*3
-f*9=5x^2+5*3x
-9f=5x^2+15x
f=-5x(x+3)/9

Answer:
B is the correct option.
Step-by-step explanation:
We have to find the inverse of the logarithmic function
Below are the steps to find the inverse:-
Step 1:-
Set f(x) =y
Step 2:-
Interchange x and y
Step 3:-
Solve for y
We know the relation:-
If
Using this relation, we have
b=2
Step 3:-
The value of y is the inverse of the function.
B is the correct option.
