Solve the system of linear equations using elimination.

Mathematics
1 answer:
N76 [4]3 years ago
8 0

Answer:

C (-2,1)

Step-by-step explanation:

−2x − y = 3 (1)

−9x − y = 17 (2)

(1) y = -2x - 3

(2) y = -9x - 17

-2x - 3 = -9x - 17

7x = -14

x = -2

y = -2(-2) - 3

y = 4 - 3

y = 1

Answer:

  17 -4i

Step-by-step explanation:

You do this the same way you would if i were a variable.

  8-(-4+5i)-(-5-i) = 8 +4 -5i +5 +i = (8 +4 +5) +(-5i +i) = 17 -4i

What is the fraction is less than 5/6 and has denominator of 8?
IrinaVladis [17]

Denominator is the number which appears at the bottom of fraction so the fraction we want is in the form X/8 and also less than 5/6

Lets start from changing the values of X from 1.

1/8 = 0.125 and 5/6 = 0.8333

2/8 = 0.25

3/8 = 0.375

4/8 = 0.5

5/8 = 0.625

6/8 = 0.75

7/8 = 0.875, this is greater than 5/6

<span>So, the fractions with denominator 8 and less than 5/6 are 1/8, 2/8, 3/8, 4/8, 5/8 and 6/8</span>

PLZ HELP ASAP SIMILARITY
PIT_PIT [208]
LY = 5.2  ,  TY = 3.9
Δ LTN is a right triangle , ∠T = 90° , TY⊥LN
∴ TY² = LY * YN
∴ 3.9² = 5.2 * YN
∴ YN = 3.9²/5.2 = 2.925

∴ LN = LY + YN = 5.2 + 2.925 = 8.125

Δ LYT is a right triangle , ∠Y = 90°
LT² = LY² + YT² = 5.2² + 3.9² = 42.25
∴ LT = √42.25 = 6.5

Δ NYT is a right triangle , ∠Y = 90°
NT² = NY² + YT² = 2.925² + 3.9² = 23.765
∴ NT = √23.765 = 4.875

The preimeter of the rectangle LINT = 2 * (LT + TN)
                                                          = 2 * ( 6.5 + 4.875 )
                                                          = 2 * 11.375
                                                          = 22.75

The land that would be settled on would have already been the Indians land. Just like in modern times, when you trespass on somebodys own property you would make them mad. This would also potentially decrease their hunting territory, further upsetting the Indians. (this isn't 5 sentences but its a start! Good luck :)
