The graph below shows a line segment MN: graph of line MN going through ordered pairs negative 2, 3 and 1, negative 3 Which of t

Katyanochek1 [597]

The line segment goes through (-2,3) and (1,-3).

The slope of the line is
$\frac{-3-3}{1-(-2)} = \frac{-6}{3} =-2$

Therefore the equation of the line segment is of the form
y = -2x + b

Because the line segments goes through (-2,3), therefore
-2(-2) + b = 3
4 + b = 3
b = -1

Answer: The equation is y = -2x - 1

What is the Order of Magnitude of the number of pennies equivalent to a quarter?

Talja [164]

Answer:

It is mainly used while doing scientific notation. If two numbers differ by one order of magnitude, one is about ten times larger than the other. If they differ by two orders of magnitude, they differ by a factor of about 100.A quarter is 0.25 dollars so the ratio between 1 dollar and a quarter is 1/0.25(it means the dollar and the quarter which is 0.25 dollars) and that equals =4

you bought your friends a heart shaped pound of chocolate caramels. You anticipate each chocolate was 50 calories. Each chocolat

Wittaler [7]

There was 25.37% error in calculations.

Step-by-step explanation:

Given,

Anticipated calories = Approx value = 50 calories

Actual calories = Exact value = 67 calories

Percent error = $\frac{|aprrox\ value-exact\ value|}{exact\ value}*100$

Percent error = $\frac{|50-67|}{67}*100$

Percent error = $\frac{|-17|}{67}*100=\frac{17}{67}*100$

Percent error = $\frac{1700}{67}$

Percent error = 25.37%

There was 25.37% error in calculations.

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.
