Answer:
-2x+3
Step-by-step explanation:
Gradient is change in y over change in x

=2
and then
+3 because that's where it cuts the Y axis

Answer:
Red Cell is 300 times larger than the virus
Step-by-step explanation:
Size in scientific Notation
- Red Cell = 9 * 10^-6
- Virus = 9 * 10^-8
Procedure.
- Count the number of zeros in the decimal
- Red Cell = 5 ; virus = 7
- And one more to each
- Red Cell = 6; virus = 7
- change the numbers to minus
- Red Cell = -6 ; virus = - 7
- The last row is the powers as shown above.
Answer
9*10^-6/3 * 10^-8
3*10^(-6 - - 8)
3*10^(- 6 + 8)
3^10^2 or 300 times larger
ANSWER
The vertex of the graph of

is

EXPLANATION
The vertex form of a parabola is given by

where

is the vertex of the parabola.
The function given to us is

This is already in the vertex form.
When we compare this to the general vertex form, we have,


and

Therefore the vertex of the parabola is

Hence the correct answer is option A.
