Answer:
The solution set is {-6, -1}.
Step-by-step explanation:
Next time, please use " ^ " to denote exponentiation: y=x^2 + 7x + 6.
This function is easily factored: y = (x + 1)(x + 6).
Setting it = to 0 and solving for x yields the zeros {-1, -6}, which are also the "solutions."
You might consider graphing this function even tho' we already have the solutions here. The y-intercept of y = x^2 + 7x + 6 is (0, 6), and, as we have already seen, the zeros / roots / solutions are (-1, 0) and (-6, 0).
The vertex is found by evaluating x = -b/(2a), which here is x = -(7) / (2*1) = -7/2. Subbing -7/2 for x into y=x^2 + 7x + 6 yields the y-value of the vertex.
Plug in F = 329, which is the given temperature in Fahrenheit, and simplify to find the Celsius equivalent temperature.
C = (5/9)*(F - 32)
C = (5/9)*(329 - 32)
C = (5/9)*(297)
C = 5*(297/9)
C = 5*33
C = 165
Therefore, 329 degrees Fahrenheit is equivalent to 165 degrees Celsius

Answer: Choice A) 165 degrees Celsius
Answer:
The percent increase is 75%
Step-by-step explanation:
2.94 ÷ 1.68 = 1.75
1.75 x 100% = 175%
175% - 100% = 75%
Hey there, we are going to use two formula's, the first formula is A=πr², and the second formula is d=2r. Now, we can solve for a, A=1/4πd²=1/4*π*6²=28.27433cm², Therefore, the answer is 28.26 cm 2
Answer:
B) 9² + 12² ≠ 18²
