- Coordinates (x, y)
- Solving systems of equations by substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = 5x
20x - 4y = 0
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em> [2nd Equation]: 20x - 4(5x) = 0
- Multiply: 20x - 20x = 0
- Combine like terms: 0 = 0
Here we see 0 does indeed equal 0.
∴ our systems has an infinite amount of solutions.
We can use the vertex form

to find the equation of the graph. We know that a is the coefficient, and since the graph opens upwards and is slightly stretched vertically, we know that a is 1/3. On the graph, we see that the vertex of the parabola is at (0,-1). Therefore, h is 0 and k is -1.
Our vertex form equation is

Which is D
Answer:
The answer is the third choice 3
Step-by-step explanation:
First you undo by doing the opposite 31 - 7 = 24 now we undo the 8 by undoing 24 divided by 8 is 3
