We evaluate b^2 - 4ac. If the answer is positive, then there are two real solutions. If it is zero, there is one real solution. If it is negative, there are 2 complex solutions. In this equation, a = 1, b = 5, c = 7. Now we plug in the numbers.
Because this answer is positive, there are two real solutions.
Answer:
A=4 b=3c=2 d=1
Step-by-step explanation:
If Anna gives 14 candies to her sister, she remains with 52. How many candies does Anna have ?
x-14=52|+14
x=52+14
x=66 candies
Using linear function concepts, it is found that the change in the breaking weight of the pennies was of -6 units of weight.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem, the function is:
y = -6x + 136.
The slope is of m = -6, hence the change in the breaking weight of the pennies was of -6 units of weight.
