Answer:

The value of x is 10.

Step-by-step explanation:

BD =CD

Which means

5x - 10 = 3x + 10

Let's solve.

5x - 10 = 3x + 10 \\  \frac{ - 3x  \:  \:  \:  \:  \:   = - 3x  \:  \:  \:    \:   \: }{2x - 10 = 10}  \\  \\ 2x - 10 = 10 \\  \frac{  \:  \:  \:  \:  \:  \:  \:  \:  \: + 10 =  + 10}{2x = 20}  \\  \\  \frac{2x}{2}  =  \frac{20}{2}  \\  \\ x = 10

Therefore, x = 10.

The parabola opens towards left, this means the squared term is y with negative coefficient.

The vertex is given to be the point (-1,-3). So, the general equation of the parabola will be like:

x=-a(y+1)^{2}-3

where a is any constant.

In the given options, only 1 such equation is available and that is option C.

So the answer to this question is option C

The graph shows the distance a car traveled, y, in x hours:
meriva

Answer:

The correct answer is 30

Step-by-step explanation:

Given: The x-axis represents the time in hours and the y-axis represents the distance in miles.

The line passes through the points (2,60) and (4,120)

To find: The rise-over-run value for the relationship in the graph.

\begin{aligned}m &=\frac{R i s e}{R u n} \\&=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\&=\frac{120-60}{4-2} \\&=\frac{60}{2} \\&=30\end{aligned}

Thus, the rise-over-run value for the relationship represented in the graph is 30.
