By solving a linear equation, we conclude that you bought 4 buns and 5 cakes.
<h3>
How many of each did I buy?</h3>
We will define the two variables:
- x = number of buns bought.
- y = number of cakes bought.
We know that you spent exactly £4.35, then we only need to solve the linear equation:
x*0.40 + y*0.55 = 4.35
We need to solve that equation for x and y, such that the values of x and y can only be positive whole numbers.
We can rewrite the equation as:
y*0.55 = 4.35 - x*0.40
y = (4.35 - x*0.40)/0.55
Now we only need to evaluate it in different values of x, and see for which value of x, the outcome y is also a whole number.
We will see that for x = 4, we have:
y = (4.35 - 4*0.40)/0.55 = 5
So you bought 4 buns and 5 cakes.

Answer:
-10, -1, 5
Step-by-step explanation:
To find the zeros of a function, you have to set each factor to zero in equations, then solve for x ....
x + 10 = 0 ... then factor 10 over (subtract 10 from each side) ...
x = -10
x-5=0
then repeat (add 5 to both sides) (and subtract 1 from both sides) ...
x -5 = 0 to x = 5
x + 1 = 0 to x = -1
