Answer:

To graph a parabola, use the coefficient a and coefficient b values from your parabolic equation in the formula x = -b ÷ 2a to solve for x, which is the first coordinate of the vertex. Next, plug x back into your equation to solve for y, which is the second coordinate of the vertex.

i dont know if it is correct though.

I've done the y = equations but I don't know how to do this one.

Consider the equation

$-10x-y=-20$

1) First row of the table

Set x=0 and solve as follows:

$\begin{gathered} -10(0)-y=-20 \\ \Rightarrow-y=-20 \\ \Rightarrow y=20 \end{gathered}$

The answer is y=20 and the pair x-y is (0,20)

2) Second row

Set x=1 and solve, as follows:

$\begin{gathered} -10(1)-y=-20 \\ \Rightarrow-10-y=-20 \\ \Rightarrow-y=-10 \\ \Rightarrow y=10 \end{gathered}$

The answers are y=10 and (1,10)

3) Third row.

Set y=0 and solve as follows:

$\begin{gathered} -10x-(0)=-20 \\ \Rightarrow-10x=-20 \\ \Rightarrow x=\frac{20}{10}=2 \\ \Rightarrow x=2 \end{gathered}$

The answers are x=2 and (2,0)

Which system below has no solution?

Alex787 [66]

Answer:

Step-by-step explanation:

A system has no solution if the 2 (or more) functions that make up the system do not intersect. The only pair of functions here that do not have an intersection is found in D. You could graph these 2 on a graphing calculator to see that this is true.
