Which ordered pair is the best estimate for the solution of the system of equations

Colt1911 [192]

The ordered pair that is the best estimate for the solution of the system of equations is (7, 1/2)

The given system of equations is:

$y=-\frac{1}{2}x + 4.......................(1)\\\\y = \frac{1}{2}x-3..........................(2)$

Equate equations (1) and (2)

$-\frac{1}{2}x + 4=\frac{1}{2}x -3$

Solve for x in the equation above

$-\frac{1}{2}x -\frac{1}{2}x =-3-4\\\\-x=-7\\\\x=7$

Substitute x = 7 into equation (1)

$y=-\frac{1}{2}x + 4\\\\y=-\frac{1}{2}(7) + 4\\\\y=\frac{1}{2}$

The ordered pair that is the best estimate for the solution of the system of equations is (7, 1/2)

Simplify h= 105sin (0.0698(90+1)) + 105

IrinaK [193]

Answer:

$h= 116.616$

Step-by-step explanation:

we have

$h= 105sin (0.0698(90+1)) + 105$

step 1

Solve (90+1)

$h= 105sin (0.0698(91)) + 105$

step 2

Solve 0.0698(91)

$h= 105sin (6.3518) + 105$

step 3

Solve sin (6.3518)

$h= 105(0.11063) + 105$

step 4

Solve 105(0.11063)

$h= 11.616 + 105$

step 5

Solve 11.616 + 105

$h= 116.616$

Use the equation and type the ordered-pairs.

matrenka [14]

Hello!

To find the y-values of the given ordered pairs, substitute the x-values into the equation, y = log₂ x.

y = log₂ 1/2, y = -1

y = log₂ 1, y = 0

y = log₂ 2, y = 1

y = log₂ 4, y = 2

y = log₂ 8, y = 3

y = log₂ 16, y = 4

Therefore, the ordered pairs of y = log₂ x is: {(1/2, -1), (1, 0), (2, 1), (4, 2), (8, 3), (16, 4)}.
