Which of these ordered pairs is a solution to the inequality?
1/4x ≤ 7/3y +2
Responses
A (80, 6)
B (48, 9)
C (40, 3)
D (2, –6)
Please show step by step as I need to learn how to do these problems. Thank you
Answer: D
Step-by-step explanation:
To determine which ordered pair is a solution to the inequality, we can substitute the values of x and y into the inequality and check if it is true.
Let's start with ordered pair A (80, 6):
1/4x ≤ 7/3y + 2
1/4(80) ≤ 7/3(6) + 2
20 ≤ 14 + 2
20 ≤ 16
This is not true, so ordered pair A is not a solution to the inequality.
Now let's try ordered pair B (48, 9):
1/4x ≤ 7/3y + 2
1/4(48) ≤ 7/3(9) + 2
12 ≤ 21 + 2
12 ≤ 23
This is also not true, so ordered pair B is not a solution to the inequality.
Next, let's try ordered pair C (40, 3):
1/4x ≤ 7/3y + 2
1/4(40) ≤ 7/3(3) + 2
10 ≤ 7 + 2
10 ≤ 9
This is false, so option C is not a solution to the inequality.
Finally, we have option D: (2, -6)
1/4(2) ≤ 7/3(-6) + 2
1/2 ≤ -14 + 2
1/2 ≤ -12
This is true, so option D is a solution to the inequality.
Therefore, the answer is D: (2, -6).

Case 2: The midpoints of the line segments are listed below:
Line segment AB: M(x, y) = (- 5, 7)
Line segment BC: M(x, y) = (- 3.5, 6)
Line segment CD: M(x, y) = (0, 4.5)
Line segment DE: M(x, y) = (2, 1)
Line segment EF: M(x, y) = (4, - 0.5)
Case 3 - Cameron made the mistake of writing the y-coordinate of point C as 6, instead of - 6.
How to determine the length and the midpoint of a line segmentIn this problem we need to determine the length and the midpoint coordinates of several line segment, whose formulae are introduced below:
Length of a line segment
L = √[(x₂ - x₁)² + (y₂ - y₁)²]
Midpoint coordinates
M(x, y) = 0.5 · (x₁, y₁) + 0.5 · (x₂, y₂)
Where (x₁, y₁) and (x₂, y₂) are the coordinates of the ends of the line segment.
Case 2 - We need to determine the midpoints of a set of line segments:
Line segment AB: A(x, y) = (- 5, 8), B(x, y) = (- 5, 6)
M(x, y) = 0.5 · (- 5, 8) + 0.5 · (- 5, 6)
M(x, y) = (- 5, 7)
Line segment BC: B(x, y) = (- 5, 6), C(x, y) = (- 2, 6)
M(x, y) = 0.5 · (- 5, 6) + 0.5 · (- 2, 6)
M(x, y) = (- 3.5, 6)
Line segment CD: C(x, y) = (- 2, 6), D(x, y) = (2, 3)
M(x, y) = 0.5 · (-2, 6) + 0.5 · (2, 3)
M(x, y) = (0, 4.5)
Line segment DE: D(x, y) = (2, 3), E(x, y) = (2, - 1)
M(x, y) = 0.5 · (2, 3) + 0.5 · (2, - 1)
M(x, y) = (2, 1)
Line segment EF: E(x, y) = (2, - 1), F(x, y) = (6, 0)
M(x, y) = 0.5 · (2, - 1) + 0.5 · (6, 0)
M(x, y) = (4, - 0.5)
Case 3 - Now we determine the length of the line segment CD: C(x, y) = (- 2, 6), D(x, y) = (2, 3)
d = √[[2 - (- 2)]² + (3 - 6)²]
d = √[4² + (- 3)²]
d = 5

The simplified result is -1. The correct option is b.
Given that:
Expression, -3/2 ÷ 9/6
To solve the given expression, follow as:
Rewrite the division as multiplication by the reciprocal of the second fraction.
-3/2 ÷ 9/6 = -3/2 × (6/9)
Now, simplify the fractions:
-3/2 × (6/9) = -3/2 × (2/3)
-3/2 × (6/9) = - (3 × 2)/(2 × 3)
-3/2 × (6/9) = -6/6
Finally, the simplified expression is -6/6. However, further simplify it by dividing the numerator and denominator by their greatest common divisor, which is 6:
-6/6 = -1
So, the simplified result is -1. The correct option is b.

Answer:
x = 4
y = 4
Step-by-step explanation:
the front triangle has two 40° angles (sum of all ∡'s must be 180°)
the unlabeled lower-left angle then is 40°; this angle corresponds to the angle in the other triangle labeled as 10y°
therefore, 10y = 40 so y = 4
Since opposite angles in a parallelogram are congruent then we can write:
40° + 25x° = 100° + 10(4)°
25x° = 140 - 40°
25x = 100°
x = 4

The parent function f ( x ) = 3 √ x is transformed to g ( x ) = 2 f ( x − 3 ) Which is the graph of g ( x ) ?
The graph of the function g(x) has an equation of g(x) = 6√(x - 3)
Identifying the graph of the function g(x)?From the question, we have the following parameters that can be used in our computation:
f(x) = 3√x
The transformed function g(x) is given as
g(x) = 2f (x − 3)
In f(x) = 3√x , we have
f(x - 3) = 3√(x - 3)
Multiply both sides by 2
So, we have
2f(x - 3) = 2 * 3√(x - 3)
Evaluate the products
2f(x - 3) = 6√(x - 3)
Recall that
g(x) = 2f (x − 3)
So, we have
g(x) = 6√(x - 3)
This means that the graph of the function g(x) has an equation of g(x) = 6√(x - 3)

what is the measure of angle jkl?
a. 110°
b. 120°
c. 130°
d. 140°
Answer:
b. 120°
Step-by-step explanation:
K is any point outside of the circle with center M.
KJ and KL are tangents to the circle at points J and L respectively drawn from point K.
MJ and ML are radii of the circle with center M.
Since, tangent is perpendicular to the radius of the circle.
\( \therefore m\angle MJK = m\angle MLK = 90\degree \\\)
Since, measure of central angle of a circle is equal to the measure of its corresponding minor arc.
\( \therefore m\angle JML = m\widehat {(JL)} \\
\therefore m\angle JML = 60\degree \\\)
Since, JKLM is a quadrilateral. Hence by angle sum postulate of interior angles of quadrilateral JKLM, we have:
\( m\angle JML + m\angle MJK + m\angle MLK \\+ m\angle JKL= 360\degree \\
\therefore 60\degree +90\degree +90\degree +m\angle JKL= 360\degree \\
\therefore 240\degree +m\angle JKL= 360\degree \\
\therefore m\angle JKL= 360\degree-240\degree \\
\huge \purple {\boxed {\therefore m\angle JKL= 120\degree}} \\\)
The measure of angle JKL is 120 degrees and the correct choice is B.
What is a circle?A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.
We are given that K is any point outside of the circle with center M.
Since KJ and KL are tangents to the circle at points J and L respectively drawn from point K. also MJ and ML are radii of the circle with center M.
We know that measure of central angle of a circle is equal to the measure of its corresponding minor arc.
Given, JKLM is a quadrilateral.
The angle sum postulate of interior angles of quadrilateral JKLM, we have:
Angle JKL + 90 + 60 + 90 = 360
Angle JKL = 360 - 240

solve for x & y that makes both expressions true.
The solution that makes both expressions true is x = 8.55556 and y = 10.31746.
To solve for x and y, we need to use a system of equations involves finding the values of x and y that satisfy both equations simultaneously.
We can start by using the first equation to solve for x:
2x + 7x = 77
Combining like terms:
9x = 77
Dividing both sides by 9:
x = 8.55556 (rounded to six decimal places)
Now that we know the value of x we can use either equation to solve for y. Let's use the second equation:
5x + 7y = 115
Substituting x = 8.55556:
5(8.55556) + 7y = 115
Simplifying:
42.7778 + 7y = 115
Subtracting 42.7778 from both sides:
7y = 72.2222
Dividing both sides by 7:
y = 10.31746 (rounded to six decimal places)

the end of the year is same, what is the value of x?
The value of x is $6,666.67.
Let the value of x dollars invested at 3% interest rate be X .If the return on both investments at the end of the year is the same, the two investments should give the same amount of money after one year. The formula for calculating the simple interest on an investment is:
I = P × R × T
Where, I is the simple interest P is the principal amount R is the interest rate T is the time duration Seema invested $4,000 at 5% interest. Using the above formula, her return after 1 year is:
I1 = 4000 × 0.05 × 1 = $200
The value of x dollars was invested at 3% interest. Using the above formula, her return after 1 year on x dollars will be:
I2 = X × 0.03 × 1 = 0.03X dollars
If the return on both investments at the end of the year is the same, then we can equate the two equations obtained for I1 and I2, then solve for X dollars.
4000 × 0.05 × 1 = X × 0.03 ×
1Simplifying this equation, we get:200 = 0.03XDividing both sides by 0.03, we get:
