Answer:
x = -2 or x = 1/3 thus: B & C
Step-by-step explanation:
Solve for x over the real numbers:
2 x^2 + 7 x - 2 = 2 x - x^2
Subtract 2 x - x^2 from both sides:
3 x^2 + 5 x - 2 = 0
The left hand side factors into a product with two terms:
(x + 2) (3 x - 1) = 0
Split into two equations:
x + 2 = 0 or 3 x - 1 = 0
Subtract 2 from both sides:
x = -2 or 3 x - 1 = 0
Add 1 to both sides:
x = -2 or 3 x = 1
Divide both sides by 3:
Answer: x = -2 or x = 1/3
Answer:
obtuse angle
Step-by-step explanation:
as it is angle 1 is greater than 90
Answer:
B. a + s = 15
6a + 4s = 76
Step-by-step explanation:
The two equations you want to write are for the two resources, tickets and dollars. We want to know the numbers of adult and senior tickets, so we assign the variables "a" and "s" to those numbers, respectively. We need to keep the meaning of these variables in mind as we write the equations.
a + s = 15 . . . . the sum of the numbers of tickets is 15 (resource = tickets)
The amount spent for tickets of a given type will be the number of tickets of that type, multiplied by the cost of tickets of that type. Then 6a represents the amount spent on adult tickets ($6 each for "a" number of tickets).
6a +4s = 76 . . . the total amount Beth spent on tickets (resource = dollars)
In summary, the two equations are ...
- a + s = 15
- 6a +4s = 76 . . . . . . matches choice B
_____
Beth bought 8 adult tickets and 7 senior tickets.
11 HOMES TO 8 AWAYS IS THE ANSWER
The hundredth place is the second number on the right side of the decimal place. In this case, it is the 4 in the number you listed above.
Rounding is simple, once you get the hang of it. :)
To round on the right side of the decimal, you look at the number to the right of the number. If the number to the right of that number is five or over, the number rounds up. But, if it is less than five, the number remains the same. Either way, the number/s to the right of the one you are rounding disappear after you are done.
So let's look at your equation. The number you wish to round up- the hundredths place is the number 4. The number to the right of the four is a six. Since that is five or over, we round up. So the number would end up being .35 pounds to the nearest hundredth.
