Answer:

35 tickets at $35, 72 tickets at $25

Step-by-step explanation:

x+y=107 -> 5x+5y=535

45x+25y=3375

simplify, divide by 5 to get

9x+5y=675

Substract

9x+5y=675

- 5x+5y=535

4x=140 -> x=35

y=107-35 = 72

A line passes through the origin and has a slope of -3 what is the equation of the line that is perpendicular to the first line

Marianna [84]

Answer: $y=\frac{1}{3}x+3$

Step-by-step explanation:

The equation of the line is Slope-intercept form is:

$y=mx+b$

Where "m" is the slope and "b" the y-intercept.

The slopes of perpendicular lines are negative reciprocal.

Then, if the slope of the first line is -3, the slope of the other line must be:

$m=\frac{1}{3}$

Substitute the point (3,4) into the equation and solve for b:

$4=\frac{1}{3}(3)+b\\ 4-1=b\\b=3$

Then the equation of this line is:

$y=\frac{1}{3}x+3$
