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.
B. 0.5 or 50%
The answer would be B because there are 10 possible colors of marbles and an equal amount of them in the bag, you want to know the probability of picking five of the ten possible colors which is 50% of the total marble colors.
Hope this helped! (Brainliest would be nice only if you think i deserve it)
Answer:
1 kilometer = 1000 meters
or
0.001 kilometers = 1 meter
We can use using graphing technology to solve the system of equations here.
So draw sketch of graphs 
and 
on graphing calculator. you will get sketch as shown
Take pointer to point of intersection as shown. It displays (x,y) coordinate of points of intersection as (9.597, 3.459) as show in figure.
Now round off these values to nearest tenth thats one digit after decimal dot.
so to round 9.597 to one decimal place we will see 2nd decimal digit(next to place where you have to round off) which is 9 here and as 9 is greater than 5 so we will increase 1st decimal place digit by 1, so round to one decimal place will be 9.6.
Similarly to round off 3.459 to one decimal place we will see 2nd decimal digit which is 5. Again as its equals 5 we will increase the 1st decimal digit by 1 for round off. So final round off to one decimal place will be 3.5
So final answer for solution set will be choice C (9.6, 3.5)
