Answer:
The slope is 
Step-by-step explanation:
Take the general equation of a straight line 
Here
is the slope of the line.
So let's get the equation of the line in the question in the same form.

Add
to both sides: 
Add
to both sides: 
Divide by
to get it into the general equation: 
Now compare it to the general equation to find the value of
. The value of
is the coefficient of
which we can see is 
Answer:

Step-by-step explanation:
Let the quadratic function be

The given points must satisfy this function;
Substitute
.

Substitute (0,-2)

Substitute (1,-4);

Put equation (2) into equation (1)



Put equation (2) into equation (3)


Add equation (4) and (5)

Divide both sides by 3

Put a=3 in equation 5.



The quadratic function is;

Answer: 2(x+3)=10 x=2
5(x+4)=25 x=1
Step-by-step explanation:
Answer: 48
Step-by-step explanation:
Answer:
16/25 = 0.64 = 64%
Step-by-step explanation:
If we want the probability of Fiona waking up before 8am for at least one of the days, we can calculate the probability of she not waking up 8am in both days, and then we do 1 minus this probability.
The probability of she not waking up 8am in one day is (1 - 2/5) = 3/5
The probability of she not waking up 8am in both days is 3/5 * 3/5 = 9/25
So, the probability of Fiona waking up before 8am for at least one of the days is (1 - 9/25) = 16/25 = 0.64 = 64%
