The answer would be the 4th one, if we consider x and HD video, and if we consider y a classic video. then it would be 5x + 2y = 31, 3x + 5y = 30! Hope this helped! Brainliest is always appreciated.
The purple line is the axis of symmetry. This is like a mirror. Everything to the left of the line is a mirror image of everything the to right.
The orange curve is the parabola. This is the name of the shape that a quadratic equation forms.
The black dots are the zeroes, x-intercepts, and the roots. These are all terms for the solutions of the graph.
The red dot is the vertex, minimum, and extremum. The vertex is peak of a parabola. Minimum refers to the lowest y-value of a graph, and extremum is a general term for all minima and maxima.
The green dot is the y-intercept. This is where the graph crosses the y-axis.
First set up equation for Raj, which is 10x + .5, .5 is the y-intercept because he got a head start of .5 hours
Ruth, 14x
10x + .5 = 14x
- .5 -.5
10x = 14x - .5
-14x -14x
-4x = -.5
/-4 /-4
x = .125 miles
So she will overtake him at more than .125 miles
I hop this is right, and hope this helps
The answer is B, they are paid based on a salary not amount of hours worked.
