Answer:
Evaluate the following exponential function when x = 1.Evaluate the following exponential function when x = 1.
f (x) = 9 (12)Squared X + 12
F(1) =
f (x) = 9 (12)Squared X + 12
F(1) =
Step-by-step explanation:
Here is one example of when you would use the friendly number strategy to subtract.
42 - 18
We will turn the 18 into a friendly number, which is going to be 20.
(42 + 2) - (18 + 3)
44 - 20
Now it is easier to subtract 44 - 20 than it is 42 -18. With 42 - 18 we would have to barrow whereas with 44 -20 we do not have to barrow and we can do it in our head easier and makes it faster.
Answer:
to complete the square, you add (b/2)^2 on both side. in this case, b is -6, half of -6 is -3, -3 squared is 9, so:
x^2-6x+9=-13+9
(x-3)^2=-4
This quadratic equation have unreal solutions
Step-by-step explanation:
Answer:
f(7) = -40
Step-by-step explanation:
f(x) = -22 – 3x + 3
Let x = 7
f(7) = -22 – 3*7 + 3
= -22 -21 +3
= - 40
3(2+q)+15
First you distribute 3 with 2 and q
(3)(2)+(3q)+15
And that gives you 6+3q+15
Next you combine like terms
6+3q+15
(3q)+(6+15) leave 3q the way it is and then add 6+15
And the answer is 3q+21
