Answer:
x=2
Step-by-step explanation:
1/2‒1/6=4/3x^2
3/6‒1/6=4/3x^2
2/6=4/3x^2
1/3=4/3x^2
1(3x^2)=4(3)
3x^2=12

The value of a collectible coin can be represented by the equation y = 2 x + 9.74, where x represents the number of years that Consuello has owned the coin and y represents the total value, in dollars, of the coin. What was the value of the coin when Consuello originally purchased it?
$4.87
$7.74
$9.74
$19.48
Answer:
The value of the coin when Consuelo originally purchased it is $9.74 ⇒ C
Step-by-step explanation:
The form of the linear equation is;
y = m x + b, where
m is the slope of the line (The rate)b is the y-intercept (initial amount, value y at x = 0)∵ The value of a collectible coin can be represented by the equation
y = 2 x + 9.74
→ Compare it with the form of the linear equation above
∴ m = 2
∴ b = 9.74
∵ x represents the number of years that Consuelo has owned the coin
∵ y represents the total value, in dollars, of the coin
→ That means the value of y at x = 0 is the value of the coin when
Consuelo originally purchased it
∵ b represents the value of y at x = 0
∵ b = 9.74
∴ The value of the coin when Consuelo originally purchased it is $9.74

1) Find the minimum and maximum values for the function with the given domain interval. Round your answers to the nearest thousandth. m(x) = ln x, given 1/10 ≤ x ≤ 1/5
The function m(x) = ln x is a natural logarithm function
The minimum value is -2.30 and the maximum value is - 1.61
How to determine the minimum and maximum values?The function is given as:
m(x) = ln x
The domain is given as:
1/10 ≤ x ≤ 1/5
At x = 1/10, we have:
m(1/10) = ln (1/10)
m(1/10) = -2.30
At x = 1/5, we have:
m(1/5) = ln (1/5)
m(1/5) = -1.61
So, we have: -2.30 ≤ m(x) ≤ -1.61
Hence, the minimum value is -2.30 and the maximum value is - 1.61

ΔABC and ΔDEF appear to be similar. Which set of measurements prove that the two triangles are similar?
Answer:
C.
Step-by-step explanation:
Similar triangles have congruent corresponding angles, and proportional corresponding sides.
The only angle given is angle A, which will correspond to angle D if the similarity statement is true. That is, angle D must be 35°. (Eliminates choice D)
__
The ratios of the given sides are AB:AC = 9:12 = 3:4. The corresponding sides would be DE:DF. (Eliminates choice A)
The remaining choices have side ratios of ...
B. DE : DF = 16 : 21 ≠ 3 : 4
C. DE : DF = 12 : 16 = 3 : 4
The set of measurements that would make ΔABC ~ ΔDEF is ...
DE = 12, DF = 16, and ∠D = 35°

Ali says that the perimeter of the rectangle on the coordinate plane is equal to 30 units , choose the correct answer that shows Ali's mistake ?
Step-by-step explanation:
I don't see answer options, but I can very well guess what went wrong :
he used the area formula to calculate the perimeter.
the area would be length × width, in our case
6 × 5 = 30 units²
but the perimeter is 2×length + 2×width, in our case
2×6 + 2×5 = 12 + 10 = 22 units

What is sine of an angle?The sine of an angle is the ratio of perpendicular to its hypotenuse.
Mathematically,
Sine of an angle = Perpendicluar/Hypotenuse
Now, it is given that a △JKL.
To find sine K we need to find the hypotenuse and Perpendicular of the triangle.
Since, Sine of an angle = Perpendicluar/Hypotenuse
So, sin K = Perpendicluar/Hypotenuse
Since K is the angle given so opposite of the angle K must be the perpendicular.
So, Perpendicular of the △JKL = JL
So, Hypotenuse of △JKL = JK or KL.
Since from the given option, it can be concluded that JK is the hypotenuse of △JKL.
Therefore, sin K = JL/JK
Thus, the ratio to be used to find sink is A. JL : JK
