Answer:
x = 5 or x = -5
Step-by-step explanation:
x^2−9=16
Add 9 to both sides
x^2 = 25
√x^2 = √25
x = 5 or x = -5
Answer:
66.7%
Step-by-step explanation:
The number of seedlings planted is 6, while the number of seedlings that survived the winter is 4. Therefore the percentage of seedlings that survived can be gotten using the formula:
Percentage of seedlings survived = (survived seedlings / total seedlings planted) * 100%
Therefore substituting values gives:
Percentage of seedlings survived = (4 / 6) * 100% = 66.7%
Answer:
26
Step-by-step explanation:
Question says that 'a' and 'b' are integers that implies we cannot have 'a' and 'b' in the form of decimals.
Now, lets expand the given equation:


Lets say:
, 
Let us consider the factor pairs of 100.

Only factor pair
gives us the integer values of 'a' and 'b'.
....equation (1)
........ equation (2)
adding equation 1 and 2, we get:



Plugging the value of 'a' in the equation 2


So the greatest possible value of 'a' is 26.
Answer:
5
Step-by-step explanation:
f(x) = 2x - 3x + 7
Plug in 2 every time you see an x within the equation: x = 2
f(2) = 2(2) - 3(2) + 7
f(2) = 4 - 6 + 7
f(2) = -2 + 7
f(2) = 5
