Step-by-step explanation:
Head(H) Tails(T)
Sample space is S (HHH,HHT,HTH,THH)
Event(HHT,HTH,THH)
so the probability is 3/4
F(x) = (x+7)²
(x+7)(x+7) = x(x+7)+7(x+7) = x² + 7x + 7x + 49 = x² + 14x + 49
(x+9)² = (x+9)(x+9) = x(x+9)+9(x+9) = x² + 9x + 9x + 81 = x² + 18x + 81
(x+5)² = (x+5)(x+5) = x(x+5)+5(x+5) = x² + 5x + 5x + 25 = x² + 10x + 25
(x-9)² = (x-9)(x-9) = x(x-9)-9(x-9) = x² - 9x - 9x + 81 = x² - 18x + 81
(x-5)² = (x-5)(x-5) = x(x-5)-5(x-5) = x² - 5x - 5x + 25 = x² - 10x + 25
I think g(x) based on the translation would be g(x) = (x+9)²
C is correct because both are overlapping lines
Answer:
x = 12
Step-by-step explanation:
Let's use the distributive rule first for both 5(x - 1) and 7(x + 1). When using the distributive rule to expand parentheses, remember to find the sum of the product of the "outside number" with each of the "inside numbers".
5(x - 1): 5 is the outside number and both x and -1 are the inside numbers.
5 * x + 5 * (-1) = 5x - 5
7(x + 1): 7 is the outside number and both x and 1 are the inside numbers.
7 * x + 7 * 1 = 7x + 7
Now, we can put these back into the equation:
5x - 5 + 3x = 7x + 7
Combine all the x's and the constants:
8x - 5 = 7x + 7
x = 7 + 5 = 12
Thus, the answer is x = 12.
Hope this helps!
