Slope-Intercept Form: y = mx + b, with m = slope and b = y-intercept

So remember that parallel lines have the same slope, while perpendicular lines have slopes that are negative reciprocals to each other. But first, we have to find out the slope of the original equation. The easiest method to find the slope is to convert this standard form equation to slope-intercept form.

Firstly, subtract 6x on both sides of the equation: $-4y=-6x-3$

Next, divide both sides by -4 and your slope-intercept form is $y=\frac{3}{2}x+\frac{3}{4}$

Now, looking at our slope-intercept form we see that the slope of the original equation is 3/2. Using what we know about parallel and perpendicular lines, the slope of a parallel line is 3/2 and the slope of a perpendicular line is -2/3

Answer:

69 degree

Step-by-step explanation:

Using cosine formula again :))

So we have

BC^2 = AB^2 + AC^2 - 2*AB*AC*cosA

BC^2 = 32^2 + 28^2 -2*28*32*cos56

BC = 28.3884 cm

So B:

AC^2 = AB^2 + BC^2 - 2*AB*BC*cosB

CosB=0.3559

B=69.14 degree

Blaine exchanges $100 for yen before going to Japan.

olasank [31]

So for this, we will be using dimensional analysis:

$\frac{\$100}{1} *\frac{88.353 \yen}{\$1} =\frac{8835.3}{1}$

In short, he should receive ¥8835.30.

Elena has bought 320 tropical fish for a museum display. She bought 7 times as many triggerfish as parrotfish. How many of each

STALIN [3.7K]

The total number of fish bought was 320. And you know she bought two types of fish. The best way to solve this is guess and check. It would be the fastest. So she bought 7 times as many trigger-fish as parrot fish that means the number of trigger-fish bought was 7p. This means 320 = 7p +p. So all you do is take educated guesses for the number of parrot fish and check if it is right. So if she bought 50 parrot fish. 7(50) + 50 = 400. Close but a bit high. Lets keep guessing. 7(35) + 35 = 245. So now we know the answer is between 50 and 35. So lets try 40. 7(40) + 40 =320. That works so we know she bought 40 parrot fish and 280 trigger-fish.
