Answer:

Each poodle requires 1 balloon(s) and each poodle requires 3 balloons.

Step-by-step explanation:

The equations that should be formed are:

3x + 3y = 12

3x + 2y = 9

In this scenario, x is the number of balloons required for a poodle, and y is the number of balloons required for a giraffe.

The question says that it should be solved using elimination.

This means that we have to completely reduce a variable to find the answer of the other remaining value. Since in both equations the coefficient of x is 3, they can cancel out when we subtract one from the other:

3x + 3y = 12

- 3x + 2y = 9

-----------------------

y = 3

This means that the number of balloons required for a giraffe is 3.

We can then put in this value of y, 3, into the equation to solve for x.

3x + 3 (3) = 12

3x + 9 = 12

3x = 12 - 9

3x = 3

x = 1

This reduces into the number of balloons required for a poodle to be 1.

We can confirm by plugging it in into the other equation.

3x + 2 (3) = 9

3x + 6 = 9

3x = 9 - 6

3x = 3

x = 1

After confirming, this should be the answer.

Hopefully this helps!

baloon poodle requires 1 and giraffe requires 3 balloons.

i really hope this is the correct answer, sorry if I'm wrong.

if you want/need an explanation you can ask me and I'll explain how i did it

Tan x = sin x / cos x , therefore tan (90-A) = ? . (All angle measurements are in degrees)

Anna11 [10]

Answer:

Option D. $\frac{1}{tanA}$

Step-by-step explanation:

tan ( 90-A ) = $\frac{sin(90-A)}{cos(90-A)}$

since sin (90-A) = cos A

and cos (90-A) = sin A

So $\frac{sin(90-A)}{cos(90-A)}=\frac{CosA}{SinA}=cot A=\frac{1}{tanA}$

Option D. $\frac{1}{tanA}$ is the correct answer.

Use a diagram to name each of the following pairs of angles. If the name doesn't exist say none

nirvana33 [79]

Answer:

see below

Step-by-step explanation:

This is a vocabulary problem, identifying the names of things on a diagram.

Angles are "interior" when they are between the "parallel" lines. They are "exterior" when they are outside those lines. They are "alternate" if they are on opposite sides of the transversal, and "same side" if they are not.

They are "vertical" if they share a vertex and have opposite rays for sides, and they are "corresponding" if they are in the same quadrant of the intersection of crossing lines. (1, 5, 9, 13 are "corresponding", for example.)

Write the slope e-intercept from of the equation of the line through the given point with the given slope. Please show your work

Zinaida [17]

The slope-intercept form is written under the form of
y=mx+b where m represent the slope and y represent y-intercept. In this case, we know that the m is 8, but we don't have b yet. To find the answer, substitute (0,5) into an equation where y=5 and x=0
y=mx+b
y=8x+b
5=8(0)+b
5=b, so we have the complete y-intercept form which is y=8x+b
Or
You can you this
y-y1=m(x-x1) where point (x1,y1) represent point (0,5) in this case which led to:
y-y1=m(x-x1)
y-5=8(x-0)
y-5=8x-8(0)
y-5=8x
Add 5 to each side
y-5+5=8x+5
y=8x+5 represent the slope-intercept form. Hope it help!
