Paris Nights sweater: $60

Markup: 35% of $60

35/100=x/60

Cross multiply

2100 divide by 100 is 21

$60 + $21 = $81

The answer is $81

Simplify <br> cosx ( tanx+cotx)
Soloha48 [4]
The first step to solving this is to use tan(t) = \frac{sin(t)}{cos(t)} to transform this expression.
cos(x) × ( \frac{sin(x)}{cos(x)} + cot(x) )
Using cot(t) = \frac{cos(x)}{sin(x)},, transform the expression again.
cos(x) × ( \frac{sin(x)}{cos(x)} +  \frac{cos(x)}{sin(x)} )
Next you need to write all numerators above the least common denominator (cos(x)sin(x)).
cos(x) × \frac{sin(x)^{2} + cos(x)^{2}  }{cos(x)sin(x)}
Using sin(t)² + cos(t)² = 1,, simplify the expression. 
cos(x) × \frac{1}{cos(x)sin(x)}
Reduce the expression with cos(x).
\frac{1}{sin(x)}
Lastly,, use \frac{1}{sin(t)} = csc(t) to transform the expression and find your final answer.
csc(x)
This means that the final answer to this expression is csc(x).
Let me know if you have any further questions.

Which best describes the equation that the graph represents?
andreev551 [17]

Answer:

y= \frac{9}{5}x

Step-by-step explanation:

Given the two points:

  • Origin (x1, y1) = (0, 0)
  • The point (x2, y2) = (5, 9)

Because the x-axis is labeled time (in minutes) and the y-axis is labeled distance (in kilometers).

=>Time, x the independent variable,and distance is the dependent variable.

We have the standard form of a linear equation is:

y= mx + b where a is the slope

We know that, the slope of the function is:

m = \frac{y2-y1}{x2-x1}

In this situatuon, m = \frac{9-0}{5-0} = \frac{9}{5}

=> y= \frac{9}{5}x + b(1)

The line that goes through (0, 0) so we substitute (0, 0) into (1), we have:

0 = \frac{9}{5}*0 + b

<=> b = 0

So our equation that the graph represents is: y= \frac{9}{5}x
