- Standard Form Equation: f(x) = ax² + bx + c
So firstly, since (0,5) is one of our values we can plug it into the standard form equation to solve for the c variable (since 0 will cancel out the a and b variable):
Now we know that the value of c is 5. Next, plug in (-1,12) into the standard form equation and simplify (remember to also plug in 5 for the c variable):
Next, plug (2,15) into the standard form equation and simplify:
Now, with our last two simplified equations we will create a system of equations:
Now, I will be using the elimination method with this system. With the system, add up the equations together and you will get:
From here, we can solve for the a variable. With it, just divide both sides by 3:
Now that we know the value of a, plug it into either equation to solve for the b variable:
<h2>Answer</h2>
Putting all of our obtained values together, your final answer is:
Answer:
4/5
Step-by-step explanation:
Okay, I'm pretty sure about this one! I might be wrong but:
If the number is prime and LESS than 13 (so it can't be 13 either), it's either 2, 3, 5, 7, or 11. Those are 5 numbers in all, and 4 of those are odd. So the fraction would be 4/5!
I might have done this wrong, but I hope it helps!! Have a nice day c:
Answer:
You would have to write a multi step equation.
4x+13=37
Since all the point connect to prove its a trapezoid, also the fact that it has 1 pair of parallel sides, and to geographic knowledge the sides and angles plus the way it is graphed on the graph it fits the definition of a trapezoid in geographic shapes. Hope this helps lots <3
<span>The factors of 12 are : 1, 2, 3, 4, 6, 12.
The factors of 15 are : 1, 3, 5, 15.
1 and 3 are the only common factors (numbers which are factors of both 12 and 15).</span>
<span>Therefore, the highest common factor of 12 and 15 is 3.</span>
