Answer:

They would never intersect because they are parallel lines. You can tell they are parallel lines because they have the same slope and they have a different y-intercept. However, this doesn't mean that there was no solutions, there were, thats how i was able to tell what their slopes and y-intercepts were. So if there is an answer that you can choose from that explains that they won't intersect because they are parallel then that is the correct answer. It may be C, but I would see if there is another option.

The measure of angle θ is 7pi/4 . The measure of its reference angle is *Blank* °, and tan θ is *blank*

sukhopar [10]

Since the measure of angle $\Theta$ is $\frac{7\Pi }{4}$

The measure of its reference angle = $\frac{7\times 180^{\circ}}{4}$

= $=315^{\circ}$

Now we have to compute the value of $\tan \Theta$

$\tan \Theta = \tan \frac{7\Pi }{4}$

$= \tan (2\Pi -\frac{\Pi }{4})$

The value of ( $(2\Pi -\frac{\Pi }{4})$ ) lies in the fourth quadrant. In fourth quadrant, the value of tan is always negative.

So, $\tan (2\Pi -\frac{\Pi }{4})$

$= -\tan (\frac{\Pi }{4})$

= -1.

1 2/5m-3/5(2/3m+1) How do you solve this problem

igor_vitrenko [27]

Step-by-step explanation:

I am not sure what you mean by "solve".

I assume you mean simplify the expression.

and then it is very tricky to find the true original expression the way you typed it.

I think you meant

1 2/(5m) - 3/(5(2/(3m + 1)))

1 = 5m/5m

1 2/(5m) = (5m+2)/5m

3/(5(2/(3m + 1))) = 3/(10/(3m + 1)) = 3/1 / (10/(3m + 1))

when dividing by a fraction, it is the same as multiplying with the upside-down fraction

so, this is the same as

3/1 × (3m + 1)/10 = (3(3m + 1)) / (10×1) = (9m + 3)/10

this would give us in total

(5m + 2)/5m - (9m + 3)/10

to do the subtraction we need to bring both fractions to the save denominator (lower part).

it seems to me the easiest one would be 10m.

so,

2×(5m + 2)/10m - m×(9m + 3)/10m =

= (10m + 4)/10m - (9m² + 3m)/10m =

= (10m + 4 - 9m² - 3m)/10m = (-9m² + 7m + 4)/10m

if we want to transform this back to a sum of fractions :

4/10m - (9m² - 7m)/10m = 2/5m - (9m - 7)/10
