How many solutions does the system x-3y = -8 x + 3y =8

Mathematics
1 answer:
MrRissso [65]3 years ago
3 0
X - 3y = -8
x + 3y = 8
---------------    Add the equations
2x =  =
x = 0

Plug zero back in to either equation and solve for y.
x - 3y = -8
0 - 3y = -8
-3y = -8
divide both sides by -3
y = 8/3

(0, 8/3)

Determine whether the following sequence is arithmetic, geometric, or neither.
Slav-nsk [51]

Answer:

B

Step-by-step explanation:

A geometric sequence has a common ratio r between consecutive terms

r = \frac{a_{2} }{a_{1} } = \frac{a_{3} }{a_{2} } = ...

\frac{-14}{-7} = 2

\frac{-28}{-14} = 2

\frac{-56}{-28} = 2

There is a common ratio of 2 between consecutive terms.

Hence sequence is geometric → B

Name a plane parallel to plane DEF
Verizon [17]
Having two opposite faces plane and parallel a plane-parallel sheet of glass.

Or ?? ⬇️

In geometry, parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel. Colloquially, curves that do not touch each other or intersect and keep a fixed minimum distance are said to be parallel.

1) Area = leg(1) * leg(2) * .5 = 15 * 36 * .5 = 270

Perimeter = leg(1) + leg(2) + hypotenuse = 15 + 36 + 39 = 90

2) Area = leg(1) * leg(2) = 20 * 80 = 1600

3) Median (divides it in 1/2)

4) Both (divides it in 1/2 and makes a 90 degree angle w/ base)

5) Altitude (makes 90 degree angle w/ base)

6)sqrt(30^2 + 16^2) = sqrt( 900 + 256) = sqrt(1156) = 34

7) sqrt(24^2 + 18^2) = sqrt( 576 + 324) = sqrt(900) = 30

8) sqrt(40^2 + 96^2) = sqrt(1600 + 9216) = sqrt(10816) = 104

9) sqrt(150^2 - 90^2) = sqrt(22500 - 8100) = sqrt(14400) = 120

10) sqrt(35^2 - 25^2) = sqrt(1225 - 625) = sqrt(600) = 10sqrt(6), approx. 24.5

If the length of FG is 6 units, what is the length of EH?
QveST [7]

FG goes through the center of the circle, so FG is diameter.

d = 2r \\ r =  \dfrac{d}{2}  \\  \\ r =  \dfrac{6}{2}  = 3

EH=r=3

Answer: EH=3
