Step-by-step explanation:
Graph each of the equation in the system on the sale coordinate axes
In this context epsilon mean "member of", so "x ϵ" means "x is a member of."
<span>Epsilon is a Greek letter and its meaning in mathematics depends on context</span>
Answer:
y = x - 8
Step-by-step explanation:
The equation of the straight line which is perpendicular to the straight line y = -x -3, will be y = x + c' ....... (1), where c' is a constant.
{This is because the product of the slopes of two mutually perpendicular straight line is -1}
Now, (3,-5) point satisfies equation (1).
Hence, -5 = 3 +c', ⇒c' = -8.
Therefore, the equation of the required straight line in slope-intercept form is y = x - 8 (Answer)
{Note: The slope-intercept form of a straight line is y = mx + c, where m is the slope of the line i.e. tanФ, and c is the length of y-axis intercept.}

Divide the cost by percentage of time to find rates of dollars per time.
P= 400/35 =11.428
Q=350/30 = 11.666
R= 200/25 = 8
S= 180/20 = 9
T= 150/15 = 10
R is the smallest amount of dollars per tim so it gets more ad time per dollar.
