What are the co-ordinance of point Q

dimulka [17.4K]

Answer:

<em>(6,3), last option</em>

Step-by-step explanation:

<u>Symmetry To A vertical line</u>

If the point Q (unknown) is symmetric to point P(2,3) with respect to x=4, it means it's located at the same distance to the line as P while keeping the same y-coordinate.

The point P has a distance of 4-2=2 units with respect to x=4. Q must have its x coordinate equal to 4+2=6, and keeping the y-coordinate equal to 3

The coordinates of Q are (6,3), last option

PLEASE HELP WITH THIS EQUATION!!! WILL GIVE BRAINLIEST AND RATING!!!!!!!

GuDViN [60]

Answer:

$-8x+6$

Step-by-step explanation:

we know that

The expression Subtract $(5x-2)$ from $(-3x+4)$ is equivalent to the algebraic equation

$=(-3x+4)-(5x-2)$

$=-3x+4-5x+2$

Group terms that contain the same variable

Combine like terms

$=(-3x-5x)+(4+2)$

$=(-8x)+(6)$

$=-8x+6$

Create the equation of a quadratic function with a vertex of (5,6) and a y-intercept of -69

Elena L [17]

If the y-intercept is at -69, meaning the point is (0, -69), thus x = 0, y = -69

$\bf ~~~~~~\textit{parabola vertex form}
\\\\
\begin{array}{llll}
\boxed{y=a(x- h)^2+ k}\\\\
x=a(y- k)^2+ h
\end{array}
\qquad\qquad
vertex~~(\stackrel{}{ h},\stackrel{}{ k})\\\\
-------------------------------\\\\
vertex~(5,6)\quad 
\begin{cases}
x=5\\
y=6
\end{cases}\implies y=a(x-5)^2+6
\\\\\\
\textit{we also know that }
\begin{cases}
x=0\\
y=-69
\end{cases}\implies -69=a(0-5)^2+6
\\\\\\
-75=25a\implies \cfrac{-75}{25}=a\implies a=-3
\\\\\\
therefore\qquad \boxed{y=-3(x-5)^2+6}$

Consider the sequence of steps to solve the equation:

marin [14]

Answer: B) Addition Property

Step-by-step explanation:

The Step 3 is: $3x-30=0$

The idea is to solve the equation, which means that you have to find the value of the variable $x$ .

As $3x-30$ is a subtraction, you need to add 30 to both sides of the equation to keep the equation balanced. This property is known as "Addition property of equality".

This property states that adding the same number to both sides of the equation, the equality does not change:

$a=b\\a+n=b+n$

Then, the Addition property of equality applied in Step 3, get you to Step 4:

$3x-30+(30)=0+(30)\\3x=30$
