Answer:
Infinitely many solutions
Step-by-step explanation:
Step 1- Distribute into the parenthesis.
2x+12= 2(x+6)
2x+12= (2)x+(2)6
Step 2- Multiply
2x+12= 2x+12
Since they are equal, they are infinite.
Answer:
Roughly 2 years
Step-by-step explanation:
3500(1.05)^t=3850
(1.05)^t=1.1
t=1.953
So roughly 2 years
Y= 21 so HQE = 42 and AQG= 21
Answer:
Step-by-step explanation:
The rate of change of the function f(x) from point 
to point 
can be calculated using formula
Given
From the graph of the function
So, the rate of change is
Answer:
<u>Option C. It is zero</u>
Step-by-step explanation:
The graph represents a quadratic equation
The quadratic equation has the form ⇒a x² + b x + c
The discriminant of the quadratic equation is D = b² - 4ac
From the discriminant of the quadratic equation, we can know the type of roots of the quadratic equation.
- If D > 0 ⇒ Two real roots.
- If D = 0 ⇒ one real roots
- If D < 0 ⇒ Two imaginary roots.
The roots of the quadratic equation are the x-intercepts of the function.
As shown at the figure, the quadratic equation has only one point of intersection with the x-axis
So, the function has only one root ⇒ D = 0
So, the discriminant of the quadratic equation = 0
<u>The answer is option C. It is zero</u>
