A quadratic equation is an equation that includes a squared term. For example, 3x + 7 = 28 is not a quadratic equation as it only has x, whereas x^2 + 5x + 6 = 0 is a quadratic equation as it includes x^2. Quadratic equations also usually have two solutions, whereas linear equations (like my first example) only have one.
I hope this helps! Let me know if you would like me to explain anything more :)
72 you take the number of options available in the first multiplied by the number available in the second multiplied by the number in the third multiplied by the number in the fourth
Answer:
v^32
Step-by-step explanation:
-4x-8=32
since it is a negative times a negative it becomes a positive

Look at that website. The part says that (ab*ad)=(ac*ae)
Doing that, we get
9*(9+11x)=10(10+8x)
81+99x=100+80x
19x=19
X=1
In this question, we have a graph given. And using that graph we have to find the value of f(1) .
f(1) means the y value when x=1 .
So we need to check the value of y at x=1 .
And if we follow the graph, we will see that at x=1, y=2.5 . So the value of f(1)=2.5 and that's the required answer .
