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!

The functions r and s are defined as follows. r(x)=2x-2 s(x)=-x^2 find the value of s(r(-3)) (please help!)
Answers
Solving equation s(r(x)) for x= -3, you find as result s(r(-3))=-64
Solving EquationsThe equations can be solved when you replace the variable x for a given value or find the zero of functions.
The question gives:
r(x)=2x-2
s(x)=-x²
First, you will find r(-3). For this, in the equation r(x)=2x-2, you should replace x for -3. Then,
r(x)=2*(-3)-2
r(x)=-6-2= -8
Like r(-3)= -8, you should replace x, in s(x), for -8.
s(x)=-(-8)²
s(x)=-64
Hence, s(r(-3)=-64.

Write an equation of a line that passes through the point (0,-2) and is perpendicular to the image shown.
options:
y= 3x −2
y= −1/3x − 2
y= 1/3x
y= 3x − 10
Answers
Answer:
Brainliest Answer would be appreciated. Option 1 is the best
Step-by-step explanation:
The slope of the line on the graph is -1/3. A perpendicular line's slope is always the negative reciprocal of it, so your slope of the perpendicular line would be 3.
Also, since you are passing through the point (0, -2), -2 would be your y-intercept, making your equation for the perpendicular line y = 3x - 2.

Name of the figure:
Measure of angle 1:
Measure of angle 2:
Measure of angle 3:
Measure of angle 4:
Answers
Answer:
Step-by-step explanation:
Remark
The way the sides of the figure are marked (they are marked as being equal.), the figure is a rhombus.
<96 and <2 + <1 are supplementary.
<1 = <2 because the diagonal bisects the angle it is connected to
Call <1 = <2 = x
96 + x + x = 180
96 96 Subtract 96 from both sides
2x =84 Divide by 2
2x/2 = 84/2
x = 42
<1 = 42
<2 = 42
Now because opposite angles in a rhombus are equal, the diagonal will make <3 and <4 = <2 + <1
<3 = 42
<4 = 42
