The sum of the roots of 8x^2- 2x
Answers
Answer:
1/4
Step-by-step explanation:
To find the roots of the expression, factor the expression by GCF.
The roots are the factors set equal to 0 and solved for x.
2x = 0
x=0
4x-1 = 0
x = 1/4
The sum is the addition of the two roots 0 + 1/4 = 1/4

Answer: it is possible to buy 3 pounds of apples
Final answer:
A linear equation is written to represent the cost of buying different amounts of fruit. If one buys 10 pounds of bananas, they could also afford to buy approximately 3.24 pounds of apples.
Explanation:
The esential first step here is to write a linear equation that can represent the different amounts of fruits you could buy. Let's denote the pounds of bananas and apples as b and a respectively. The cost per pound of bananas and apples can be represented as 0.49b and 0.34a respectively. The total cost is $6.00. Hence the equation becomes:
0.49b + 0.34a = 6.00
With this equation, we can calculate the possible pounds of apples you could buy with 10 pounds of bananas. Substitute b = 10 into the equation:
0.49(10) + 0.34a = 6.00
4.9 + 0.34a = 6.00
By subtracting 4.9 from both sides of the equation and then dividing by 0.34, we can solve for a:
a ≈ 3.24
Therefore, with 10 pounds of bananas, it would be possible to buy approximately 3.24 pounds of apples with the remaining amount of money.

Answer:
4.200
Step-by-step explanation:
Change the divisor 0.9 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.
We then have the equations:
37.8 ÷ 9 = 4.200
and therefore:
3.78 ÷ 0.9 = 4.200
Both calculated to 3 decimal places.
Final answer:
The division of 3.78 by 0.9 equals 4.2 after rounding to the nearest tenth. The given problem is an arithmetic division question typically encountered in mathematics. The keyword 3.78 is the number being divided by 0.9.
Explanation:
The division question posed: 3.78 divided by 0.9, is a simple arithmetic problem. To solve, we will perform the division calculation directly. First, we divide 3.78 (the dividend) by 0.9 (the divisor). This yields a quotient of approximately 4.2. Thus, 3.78 divided by 0.9 equals 4.2 when rounded to the nearest tenth. This division problem would be typically encountered in arithmetic, a branch of mathematics that deals with numbers and numerical computation.

x + 2y = -10
First solve for x in the second equation
x + 2y = -10
x = -10 - 2y
Now we have a value for x so we can substitute it into the other equation
-4 (-10 - 2y) + 6y = 12
Now solve for y
40 + 8y + 6y = 12
40 + 14y = 12
14y = -28
y = -2
Now we have a value for y that we can plug into one of the original equations so we can solve for x
x + 2y = -10
x + 2(-2) = -10
x - 4 = -10
x = -6
Your solution set is
(-6, -2)
