Answer:

x+y=-13......i

xy=42........ii

from ii, x =42/y...iii

put iii in i

42/y +y =-13

(42+y²)/y=-13

42+y²=-13y

y²+13y+42=0

y²+6y+7y+42=0

(y²+6y)+(7y+42)=0

y(y+6)+7(y+6)=0

(y+7)(y+6)

y= -7 or -6

if y=-7,

x-7=-13

x=-6

if y=-6

x-6=-13

x=-7

x= -7,-6

y=-6,-7

Which of the following describes the end behavior of y= -x^2 + bc + c as x approaches either positive or negative infinity?
NNADVOKAT [17]
<span>y= -x^2 + bc + c represents a vertical parabola that opens down.  As x approaches either + or - infinity, the function approaches  - infinity.  Imagine an upside down parabola; doing so will confirm this answer.

A length of string that is 22 feet long is being cut into pieces that are 1/3 foot long. how many pieces will there be
Anika [276]
One foot is equivalent to 12 inches. If we get 1/3 of 12 inches, then it would be 4 inches. Given that the length of the string is 22 feet long, we first have to multiply 22 by 12 and we get 264 inches. Then divide this one by 4, so the number of pieces there will be is 66. Hope this answers your question.

Find the volume to the nearest cm3<br> 20 cm<br> 35 cm<br> 12 cm
riadik2000 [5.3K]
Answer: 10380cm^3

Explanation:

Find the volume of half cylinder:

V = (pi x r^2 x h)/2 (I use pi = 22/7 for simplifying)
V = 22/7 x 6^2/2 x 35
V = 22/7 x 36/2 x 35
V = 22/7 x 35 x 18
V = 22 x 5 x 18
V = 1980cm^3

Find the volume of the rectangle:

V = 20 x 35 x 12
V = 240 x 5 x 7
V = 1200 x 7
V = 8400cm^3

Find the volume of the whole shape:

V = 1980 + 8400
V = 10380cm^3

How to do Trigonometry
Ann [662]
For trigonometry, the main components that comprise this topic are the special wave functions, sine, cosine, and tangents. You need to understand their relationships with each other, and further develop your understanding on their role in geometry.

You need to conceptually grasp how right angle triangles are formed, and how to develop angles and sides based on incomplete information, using the three main wave functions.

On top of this, you will need to understand how each wave function transforms, such as being able to graph such wave functions with a change in amplitude and period. When doing trigonometry, you will also need to understand the subtle differences between radian angles and degree angles, and how to convert radians into degrees and vice versa.
