Answer:

-4(x-4)²+9y(y+4)=0

Step-by-step explanation:

If we put the -64 with the x’s instead of the y’s, we get:

-4x²+32x-64+9y²+36y=0

-4(x²-8x+16)+9y(y+4)=0

-4(x-4)²+9y(y+4)=0

Please help!!<br> find the value of the trig ratio.
GenaCL600 [577]
<h3>Background:</h3>

So with sine cosine and tangent, try remembering the following:

Sin : Opposite / Hypotenuse

Cos: Adjacent / Hypotenuse

Tan: Opposite / Adjacent

Or just remember "Soh-cah-toa".

<h3>Thinking Process:</h3>

Anyways, with this, its asking for the sine ratio of angle Z. So we need the opposite side length and the hypotenuse side length

For the opposite side length, look to see where the angle is "opening" up towards, like a door that is opening. With this, Angle Z is opening up towards the Side XY, which has a length of 21.

To find the hypotenuse, it is always the largest side length of a right triangle. It is also where the right angle opens up it's "door" up to. This would be Side XZ, which has a length of 29.

<h3>Answer:</h3>

With both of these, back to the ratio formula:

Sin : Opposite / Hypotenuse

To finish the question, simply plug in the values that were found above.

This will give you:

Sin Z : <u><em>21 / 29</em></u>

This will be Choice A.

kupik [55]
Let x = box 1 and y = box 2

32 - 8 = 24
24 / 2 = 12
12 + 8 = 20

Box 1 = 12
Box 2 = 20

12 + 20 = 32 pounds

Y=-5x i ned help i forgot how to do this i really forgot and im in clas with my laptop
Galina-37 [17]

When you're graphing a line in slope-intercept form (y = mx + b), your first step is to look at b, which is your y-intercept. The y-intercept is where your line touches the y-axis.

Slope-intercept form is y = mx + b, but for y = -5x doesn't have a b, so you have to add one. You can do this by adding + 0 to the end, since it won't change your equation.

y = -5x + 0

b = y-intercept = 0

m = slope = -5

So, your line will start at 0 on the y-intercept, which will be at the origin point (0,0).

Your slope is -5, or \frac{-5}{1}, so you'll go down 5 and then to the right 1.

A few points on your line should be (0,0), (1,-5), and (-1,5).
