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.
Answer:
Pounds of grapes: 11
Total cost: $8.97
Step-by-step explanation:
Because when you look at the prices, the last answer (Pounds of grapes: 11
Total cost: $8.97)is the most correct because it is adding by 2 (2, 4, 6, 8) every time. Its not exactly 8 but its the closet number :)
Y = x - 6
Please let me know if you need explanation.
Answer:
24 GB
Step-by-step explanation:
Subtract the amount of money that was from the monthly plan:
75.99 - 59.99
= 16
Divide this by 4 to see how many extra GB were used:
16/4
= 4
This means that 4 GB were used beyond 20 GB.
This means 24 GB were used in total
I notice that it turns out to be the opposite of the negative number if I did this correctly....
