Could you help me solve y = x^2+6x+7?
Answers
Answer:
x ≈ -1.585786438 or x ≈ -4.414213562
y = 7
Step-by-step explanation:
This should be a parabola function.
Let y = 0 so we can find the two x-intercepts. (x1,0) and (x2,0)
x^2+6x+7 = 0
Using the quadratic equation, we get:
x ≈ -1.585786438 or x ≈ -4.414213562
Now we can find y by setting x = 0, so that we get a y-intercept. (0,y)
y = 0^2+6(0)+7
y = 7

Answer:
936
Step-by-step explanation:
Therefore you multiply 6 by 18 = 6×18= 108
1,044 - 108 = 936
So therefore the total is 936
Final answer:
The cost of each ticket before insurance is $156. This is obtained by subtracting the total cost of the insurance from the total amount spent and then dividing by the number of tickets.
Explanation:
The subject of this question seems to be an exercise in elementary algebra. If a family buys 6 airline tickets online and also purchases travel insurance that costs $18 per ticket, then the amount spent on insurance alone is $18 * 6 = $108. We know that the total cost, including the tickets and the insurance, is $1,044. Therefore, to find out the cost of the tickets alone, we subtract the cost of the insurance from the total cost: $1,044 - $108 = $936, which will be the cost for the tickets alone. So, the cost of each ticket is $936 / 6 = $156. Therefore, each ticket cost $156 before insurance.

Answer:
Cai's Would Be Bluer
Step-by-step explanation:
Since 2/5 is 40% and 5/11 is 45% Cai's would be bluer!
Final answer:
Cai's paint will be bluer because she used a higher percentage of blue paint (45.45%) in her mix compared to Casho who used 40% blue paint.
Explanation:
In order to determine whose paint mix will be bluer, we must compare the ratio of blue to red paint in each student's mix. Cai mixes 5 cups of blue and 6 cups of red paint. Casho mixes 2 cups of blue and 3 cups of red paint. We find the percentage of blue paint by dividing the amount of blue paint by the total amount of paint and then multiplying by 100. For Cai, it would be (5 / (5 + 6)) * 100 = 45.45% blue. For Casho, it would be (2 / (2 + 3)) * 100 = 40% blue. Thus, Cai's purple paint will be bluer because it has a higher percentage of blue paint.
