Answer:
x = ± 2
Step-by-step explanation:
Given
2x² + 11 = 131 ( subtract 11 from both sides )
2x² = 120 ( divide both sides by 2 )
x² = 60 ( take the square root of both sides )
x = ± = ± = ± 2
1/x is smallest when x is the largest it can be, so it is 1/3
1/y is smallest when y is the largest it can be, so it is 1/5
The average of 1/3 is 1/5 can be found by adding them together and dividing by 2:
1/3 + 1/5 = 5/15 + 3/15 = 8/15
Divide it by 2:
4/15
The answer is C.
Answer: $3 per pound
Step-by-step explanation:
Since Carson buys 4 pounds of peaches for $12, you can find the value of one pound by dividing 4 by 4. You must also divide the 12 by 4. In conclusion, you pay $3 per pound.
Answer:
Step-by-step explanation:
The line passes through (2, 8) and (4, 12). Slope m = rise/run = (12 - 8)/(4–2)= 2
if (2,8) is taken as (x1,y1)
Equation of straight line is y - 8 = m(x-2) i.e y - 8= 2(x- 2)
