Define operation $\heartsuit$ so that \[ a \heartsuit b = \dfrac{a + b}{2}. \] Let $H$ be a function defined by \[H(x,y,z) = \left(x \heartsuit y\right) \heartsuit z - x \heartsuit \left(y \heartsuit z\right). \] Write an expression for a simplified version of this function: $H(x,y,z) = \boxed{\phantom{blaaaaaaaaaa^2_2}}$ Write an expression, not an equation. Sample answer: $x + y + z$
Answers
Answer:
(-x+z)/4
Step-by-step explanation:
Evaluate the $\heartsuit$ operation to simplify.
\begin{align*}
H(x,y,z) &= \left(x \heartsuit y\right) \heartsuit z - x \heartsuit \left(y \heartsuit z\right) \\
&= \left(\dfrac{x+y}{2}\right) \heartsuit z - x \heartsuit \left(\dfrac{y+z} 2\right) \\
&= \dfrac{\dfrac{x+y}{2} + z}{2} - \dfrac{x + \dfrac{y+z}{2}}{2}
\end{align*}This looks ugly, but it works out! Continue by multiplying each fraction's numerator and denominator by $2$, in order to eliminate the complex fractions.
\begin{align*}
H(x,y,z) &= \dfrac{\dfrac{x+y}{2} + z}{2} - \dfrac{x + \dfrac{y+z}{2}}{2} \\
&= \dfrac{x + y + 2z}{4} - \dfrac{2x + y + z}{4} \\
&= \dfrac{(x+y+2z) - (2x + y + z)}{4}
&= \dfrac{-x+z}{4}
\end{align*}Surprisingly it simplifies all the way down to $H(x,y,z) = \boxed{\dfrac{-x + z}{4}}$. The value of $y$ is not even used!

Ecologists measure the body length and wingspan of 127 butterfly specimens caught in a single field.
Answers
The wingspan of 127 butterfly specimens is an illustration of the line of best fit
The equation of the line of best fit is y = 3xThe slope means that as the wingspans increase and lengths of these butterflies increaseHow to determine the equation of the line?From the line of best fit of the graph (see attachment), we have the following points
(x,y) = (0,0) and (20,60)
Since the line passes through the origin, the equation of the line would be:
[tex]y = \frac{y_1}{x_1} * x[/tex]
So, we have:
[tex]y = \frac{60}{20} * x[/tex]
[tex]y = 3x[/tex]
Hence, the equation of the line of best fit is y = 3x
Interpret the slopeIn (a), we have the slope to be:
Slope = 3
The slope (3) is greater than 0.
This means that as the wingspans increase and lengths of these butterflies increase

100 points!!!!! How many more brick houses did Company N build than Company M?
Answers
Answer:
company N built 10 more brick houses
Step-by-step explanation:
if company M builds 2x as many wooden houses as the do brick houses that would be 1/2 of 100 which is 50, and the ratio of wood houses to brick houses for company M is 5:3, 5x20=100 3x20=60. 60-50=10
Answer:
10 houses
Step-by-step explanation:
If Company M builds half as many brick houses as wood houses, then if this company builds 100 wood houses, it builds 50 brick houses.
For Company N, create a linear equation showing the relationship between wood houses (x) and brick houses (y). For every increase in x by 5, y increases by 3:
y = (3/5)x
Therefore, when x = 100: y = (3/5)(100) = 60
So Company N builds 60 brick houses when it builds 100 wood houses.
Company N - Company M = 60 - 50 = 10 houses
Therefore, Company N built 10 more brick houses than Company M.

The volume of this triangular prism is 32 cubic inches. What is the value of d?
Answers
Answer:
Divide the volume by the length of the prism to get the area of the face:
468/13 = 36 square yards.
The area of the face ( triangle) is 1/2 x base x height
Replace with what you have:
36 = 1/2 x 9 x g
Multiply both sides by 2 to remove the 1/2:
72 = 9 x g
Divide both sides by 9 to find g:
g = 72 /9
g = 8 yards.

Answers
Answer:
x = 125°
Step-by-step explanation:
There are 7 angles in this shape. The sum of the angles in a shape like this is calculated using a formula.
Total of angles
= (n - 2)•180°
Put in 7, because there are 7 angles.
= (7 - 2)•180°
= 5•180°
= 900°
So the total of the angles should be 900°. We know all of the angles except one.
900° = 123°+129°+128°+128°+132°+135°+ x
900° = 775° + x
Subtract 775.
125° = x
The missing angle is 125°.

Answers
The total amount Bianca has to pay monthly to avoid interest capitalization is $13.43.
What is compound interest?Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.
The formula for the final amount of annual payment is given as,
[tex]A_p=P\times\left(\dfrac{r}{1-1+r}\right)^t\\[/tex]
Here, P is principal amount, the rate is r and time period is t.
Bianca took out a $2,600 unsubsidized stafford loan. She will be attending school for four years, and she wishes to have the loan paid off five years before its normal ten-year duration is finished.
Total months in ten years,
[tex]t=10\times12\\t=120[/tex]
The loan has an interest rate of 6.2%, compounded monthly. The interest rate is,
[tex]r=0.062[/tex]
Put the values in the above formula as,
[tex]A_p=(2600)\times\left(\dfrac{0.062}{1-1+0.062}\right)^{120}\\A_p=161.32[/tex]
Total payment paid by her in 1 year of time is,
[tex]M_p=\dfrac{161.32}{12}\\M_p=13.43[/tex]
Thus, the total amount Bianca has to pay monthly to avoid interest capitalization is $13.43.

2x² - 12 + 8x
Setting up the equation:
Let that [SOMETHING] be L
⇒ 3x² + 8x - 16 - (L) = x² - 4To avoid confusion, let's use parenthesis:
⇒ (3x² + 8x - 16) - (L) = (x² - 4)Simplifying the equation:
Subtract "(3x² + 8x - 16)" both sides to isolate "(L)":
⇒ (3x² + 8x - 16) - (3x² + 8x - 16) - (L) = (x² - 4) - (3x² + 8x - 16)⇒ -(L) = (x² - 4) - (3x² + 8x - 16)Take the "-" in the parenthesis:
⇒ -(L) = (x² - 4) + (-3x² - 8x + 16)Open the parenthesis:
⇒ -L = x² - 4 - 3x² - 8x + 16Combine like terms and simplify:
⇒ -L = x²(1 - 3) + (-4 + 16) - 8x⇒ -L = x²(-2) + (12) - 8x⇒ -L = -2x² + 12 - 8xPut both terms in parenthesis:
⇒ -(L) = (-2x² + 12 - 8x)Multiply both sides by -1:
⇒ (L) = -(-2x² + 12 - 8x)⇒ L = 2x² - 12 + 8xThus, the [SOMETHING] is 2x² - 12 + 8x.
