Use the following graph to determine which function is best modeled on the graph.
Which equation represents the value of x?
remember Pythagorean theorem
if we have a right triangle with legs a and b and hytponuse c then
[tex]a^2+b^2=c^2[/tex]
we are given a right triangle with legs x and y and hypotohuse 10
so therfor
[tex]x^2+y^2=10^2[/tex]
[tex]x^2+y^2=100
solve for x
minus y² from both sides
[tex]x^2=100-y^2[/tex]
sqare root both sides
[tex]x=\sqrt{100-y^2}[/tex]
the answer is the 4th option
An equation represents the value of x is x=√100-y².Therefore, option D is the correct answer.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
From the given triangle ABC, AB=x units, BC=y units and AC=10 units
By using Pythagoras's theorem, we get
10²=x²+y²
x²=100-y²
x=√100-y²
Therefore, option D is the correct answer.

if the x intercept of a line is positive and the y intercept is negative, does the line slant upwards or downwards from left to right?
If the x-intercept of a line is positive and the y-intercept is negative, the line will slant downwards from left to right.
Explanation:The line will slant downwards from left to right. The x-intercept being positive means that the line crosses the x-axis at a point to the right of the origin. The y-intercept being negative means that the line crosses the y-axis at a point below the origin. Since the slope of a line represents the direction and steepness of the line, a positive slope combined with a negative y-intercept indicates a line that slants downwards.

The coordinates of the vertices of quadrilateral RSTU are R(−4, 1) , S(4, −1) , T(3, −6) , and U(−5, −4) . Which statement correctly describes whether quadrilateral RSTU is a rectangle?
Answer:
For k12- the answer is Quadrilateral RSTU is not a rectangle because it has no right angles.
Step-by-step explanation:
Solution: A quadrilateral RSTU whose vertices are R(−4, 1) , S(4, −1) , T(3, −6) , and U(−5, −4).
RS = [tex]\sqrt{(4+4)^{2}+(-1-1)^{2}} =\sqrt{64+4}= \sqrt{68}[/tex]
ST= [tex]\sqrt{(4-3)^{2}+(-1+6)^{2}}= \sqrt{1+25} =\sqrt{26}[/tex]
TU=[tex]\sqrt{(3+5)^{2}+(-6+4)^{2}}= \sqrt{64+4}= \sqrt{68}[/tex]
UR =[tex]\sqrt{(-5+4)^{2}+(-4-1)^{2}}= \sqrt{1+25} =\sqrt{26}[/tex]
→RS=TU, and ST=UR⇒ Opposite sides are equal.
Slope of RS = [tex]\frac{-1-1}{4+4} = \frac{-2}{8}= \frac{-1}{4}[/tex]
Slope of TS= [tex]\frac{-6+1}{3-4} =\frac{-5}{-1}=5[/tex]
Slope of RS × Slope of TS = -1/4 × 5 = -5/4 ≠ -1, So lines are not perpendicular.
∴ quadrilateral RSTU is not a rectangle.
Thomas collects dimes and quarters in his change jar. if he has 8 more dimes than quarters, and the total amount of money in the jar is $26.70, find the number of each type of coin in the jar.
Using algebraic expressions, we figured out that Thomas has 74 quarters and 82 dimes in his change jar, based on the total value of $26.70 and the fact that he has 8 more dimes than quarters.
Explanation:To solve the problem involving the collection of dimes and quarters in Thomas's change jar, we need to use algebra. Let's define the variables first: let q be the number of quarters and q + 8 be the number of dimes since Thomas has 8 more dimes than quarters.
Since each quarter is worth $0.25 and each dime is worth $0.10, we can set up the following equation to represent the total amount of money ($26.70):
0.25q + 0.10(q + 8) = 26.70
Now, we simply solve for q:
Multiply each term within the parenthesis by 0.10:0.25q + 0.10q + 0.80 = 26.70Combine like terms:0.35q + 0.80 = 26.70Subtract 0.80 from both sides to isolate the variable term:0.35q = 25.90Divide both sides by 0.35 to find q:q = 25.90 / 0.35q = 74Therefore, Thomas has 74 quarters. To find the number of dimes:
q + 8 = 74 + 8 = 82
Thus, Thomas has 82 dimes.
Thomas's change jar has a total of 74 quarters and 82 dimes.
A data set contains an independent and dependent variable. Which must be true of the data set if a linear function can be used to represent the data?
The set must have a constant additive rate of change.
The set must have a constant multiplicative rate of change.
The values in the set must be positive.
The values in the set must be increasing.
Answer:- The set must have a constant additive rate of change.
Explanation:-
Let X be a data set contains an independent and dependent variable.
The standard linear function is given by
[tex]y=mx+c[/tex] , where x is a independent variable and y is a dependent variable and m,c are the constants.
for m =1, y=x+c
for m=2, y=2x+c=x+x+c
for m=3, y=3x+c=x+x+x+c
1.Thus ,the set must have a constant additive rate of change.
2.The set must not have a constant multiplicative rate of change as the function will become exponential function given by [tex]y=Ab^X[/tex] which is not linear .
3.The values in the set can be positive or negative as the domain for linear function is the set of real numbers.
4.The values in the set must be increasing it is not necessary.

Two lines intersect to form a linear pair with equal measures. One angle had the measure 2x and the other angle had the measure (2y-10) find the value of x and y
Final answer:
To find the values of x and y, set up an equation by equating the two angles and solve for x and y using the given measures.
Explanation:
To find the values of x and y, we need to equate the two angles and solve for x and y.
According to the given information, the measure of one angle is 2x, while the measure of the other angle is 2y - 10.
Since the two angles are equal, we can set up the equation: 2x = 2y - 10.
Now, we can solve for x and y.
2x = 2y - 10
x = y - 5
So, the value of x is y - 5.
The values for x and y are found by solving the system of equations that arise from setting up the condition that two angles forming a linear pair add up to 180 degrees and are equal. The solution is x = 45 and y = 50.
Explanation:The student's question involves finding the values of x and y when two lines intersect to form a linear pair with equal measures. Since the angles form a linear pair, they add up to 180 degrees. Therefore, we must set up an equation 2x + (2y - 10) = 180 to find the values of x and y. Because the question tells us the angles are equal, we also know that 2x = 2y - 10. Solving this system of equations will provide the values for x and y.
To solve for x, we can use the second equation directly, 2x = 2y - 10. Since the angles are equal, we substitute the first angle's measure for the second, meaning x = y - 5. Then, we can substitute x into the first equation: 2(y - 5) + 2y - 10 = 180, simplifying it to 2y - 10 + 2y - 10 = 180, which further simplifies to 4y - 20 = 180. Finally, adding 20 to both sides and then dividing by 4 gives us y = 50. With the value of y, we can then find x: x = y - 5, so x = 50 - 5, meaning x = 45.

Answer:
A. [tex]g(x)=-x^2[/tex]
Step-by-step explanation:
In flipping across x-axis a function gives its mirror image through the x-axis,
That is, when a function f(x) is flipped over x-axis,
Then the new function would be -f(x).
Here, the given function,

A computer company can sell 130 boxes of printer paper each week at a price of $9 per box. For each $1 increase in the price, it will sell 10 fewer boxes per week. What price per box will provide the maximum revenue for the computer company?
$9
$10
$11
$12
The maximum revenue for the computer company is achieved at the price of $11 per box which is calculated based on the decrease in quantity sold with every $1 increase in price.
Explanation:To find the price per box that will provide the maximum revenue for the computer company, we need to analyze how changes in price affect the number of boxes sold and the revenue generated. The company sells 130 boxes of printer paper each week at $9 per box. For each $1 increase in price, it will sell 10 fewer boxes.
Let's define the revenue function as R(p) where p is the price per box. The initial revenue is 130 boxes × $9. For each $1 increase, the revenue function becomes (130 - 10(p - 9)) × p. We need to find the value of p that maximizes this revenue function.
Let's calculate:
At $9: R($9) = 130 × $9 = $1170At $10: R($10) = (130 - 10(1)) × $10 = 120 × $10 = $1200At $11: R($11) = (130 - 10(2)) × $11 = 110 × $11 = $1210At $12: R($12) = (130 - 10(3)) × $12 = 100 × $12 = $1200We can see that the revenue is maximum at $11 per box. So, the price per box that will provide the maximum revenue for the computer company is $11.
