Answer:

\large{\textbf{x = 0, 3}\\}

Step-by-step explanation:

\large{\textup{Given}:\\$5x^2 = 15x$\\$\implies 5x^2 - 15x = 0$\\\textup{Taking $x$ common outside, we get:}\\$x\{5x - 15 \} = 0$\\\textup{Then we have two possibilities for $x $}\\$i.e., x = 0$ \hspace{5mm} \textup{or}  \hspace{5mm} $5x - 15 = 0 \implies x = 3$\\$$\therefore x = 0, 3 $$}

Which statement accurately describes how to reflect point A(3,-1) over the y-axis?
Lyrx [107]

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

The rule of the reflection of a point over the y-axis is equal to

A(x,y) ----->A'(-x,y)

That means -----> The x-coordinate of the image is equal to the x-coordinate of the pre-image multiplied by -1 and the y-coordinate of both points (pre-image and image) is the same

so

A(3,-1) ------> A'(-3,-1)

The distance from A to the y-axis is equal to the distance from A' to the y-axis (is equidistant)

therefore

To reflect a point over the y-axis

Construct a line from A perpendicular to the y-axis, determine the distance from A to the y-axis along this perpendicular line, find a new point on the other side of the y-axis that is equidistant from the y-axis

Y=109x <br>y=79x+2506<br> can some one solve both equations and a graph would be helpful plz
Amiraneli [1.4K]

Answer:

x ≈ 83.533

y = 9105.13

Step-by-step explanation:

Step 1: Substitution

109x = 79x + 2506

30x = 2506

x = 83.533

Step 2: Plug <em>x</em> in

y = 109(83.533)

y = 9105.13
