Answer:
For the first test the score was 89 and on the second test it was 96
Step-by-step explanation:
To find the answer we make the situation into an algebraic expression.
![x + (x - 7) = 185 \\ 2x - 7 = 185 \\ 2x = 185 + 7 \\ 2x = 192 \\ \frac{2x}{2} = \frac{192}{2}](https://tex.z-dn.net/?f=x%20%2B%20%28x%20%20-%207%29%20%3D%20185%20%5C%5C%202x%20%20-%20%207%20%3D%20185%20%5C%5C%202x%20%3D%20185%20%20%2B%207%20%5C%5C%202x%20%3D%20192%20%5C%5C%20%20%5Cfrac%7B2x%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B192%7D%7B2%7D)
192 divided by 2 is 96; hence
![x = 96 \\ x + (x - 7) = 185 \\ 96 + (96 - 7) = 185 \\ 96 + 89 = 185](https://tex.z-dn.net/?f=x%20%3D%2096%20%5C%5C%20x%20%2B%20%28x%20-%207%29%20%3D%20185%20%5C%5C%2096%20%2B%20%2896%20-%207%29%20%3D%20185%20%5C%5C%2096%20%20%2B%2089%20%3D%20185)
Answer: YES
Solution:
4x-5=2x+3
2x-8=0
X=4
Y=8+3=11
This is the same as saying (6x^2)^3. We can take the derivative using the chain rule. With the chain rule, you multiply by the power, decrease the power by 1, and multiply by the derivative of the inside.
3(6x^2)^2*12x
or
36x*(6x^2)^2
Hope this helps<span />
F(1) = 7
f(2) = 7 + 6 = 13
Recursive formula => f(n + 1) = f(n) + 6
Next term = 31 + 6 = 37.
Answer:
The statement represents the IDENTITY PROPERTY OF ADDITION.
Step-by-step explanation:
Here, the given expression is 8 + 0 = 8
IDENTITY ELEMENT : Identity element is a special type of element in a given set of system, such that any number remains UNALTERED if operated with the identity element.
⇒ a + X = X for, a ≡ IDENTITY ELEMENT
Now, 8 + 0 = 8
Comparing it with the above equation , we get
0 ≡ IDENTITY ELEMENT in the given Binary operation of Addition.
Hence, the statement represent the IDENTITY PROPERTY OF ADDITION.
