Solve the system of linear equations using either substitution or the elimination method.

lara31 [8.8K]

Answer:

x = -1

y = 2

Step-by-step explanation:

x + y = 1

y = -x + 1

y = -x + 1 (Multiply this by -1)

y = 3x +5

-y = x - 1

y = 3x +5

0 = 4x + 4

4x = -4

x = -1

x + y = 1

-1 + y = 1

y = 2

Answer:

The large sample n = 1713.96

Step-by-step explanation:

Explanation:-

given the population proportion was estimated to be 0.22

population proportion (P) = 0.22

The 95 % level of significance = 1.96≅ 2

The margin of error = 0.02

The formula of margin error

$\frac{2\sqrt{p(1-p)} }{\sqrt{n} } = 0.02$ … ( i )

Substitute 'p' values in equation (1)

$\frac{2\sqrt{0.22(1-0.22)} }{\sqrt{n} } = 0.02$

cross multiplication and simplification, we get

$2X0.414= 0.02 \sqrt{n}$

$\frac{2X0.414}{0.02} = \sqrt{n}$

$41.4 = \sqrt{n}$

squaring on both sides, we get

the large sample n = 1713.96

X = 1/2at^2 Solve for t. 1. 2. 3. 4.

mash [69]

Answer:

sqrt(2x/a) = t

Step-by-step explanation:

X = 1/2at^2

Multiply by 2 on each side

2x = 2*1/2at^2

2x =at^2

Divide by a

2x/a=a/a t^2

2x/a =t^2

Take the square root of each side

sqrt(2x/a) =sqrt(t^2)

sqrt(2x/a) = t
