Answer:

x = 41

y = 24

Step-by-step explanation:

Systems of equations is,

-2x - 7y = -250 ------(1)

4x - y = 140 ------(2)

Equation (1) multiplied by 2 then added to equation (2)

 -4x -14y = -500

(+)   4x - y = 140  

         -15y = -360

            y =

           y = 24

by putting y = 24 in equation (2),

4x - 24 = 140

4x = 140 + 24

x =

x = 41

For x = 41 and y = 24 both the equations are true.

Equation (1),   -2(41) - 7(24) = -250  [True]

Equation (2),   4(41) - (24) = 140  [True]

Step-by-step explanation:

Which input value produces the same output value for the two functions ​
Lady bird [3.3K]

Answer:

Completion to the first table for f(x)=\frac{2}{3} x+7 is {-1, 1, 3, 5}

Completion to the second table for g(x)=2x+16\\ is { -8, -2, 4, 10}

the option is x=-6

Step-by-step explanation:

\frac{2}{3} (-12)+7= -1

\frac{2}{3} (-9)+7=1

\frac{2}{3} (-6)+7=3

\frac{2}{3} (-3)+7=5

2(-12)+16=-8

2(-9)+16=-2

2(-6)+16=4

2(-3)+16=10

Hope this helps and is correct.

Using vector concepts, it is found that:

The component form is of approximately (-9.58, 7,22). It means that the ship is about 9.58 miles to the west and about 7.22 miles to the north of where the ship left the port.

<h3>How can a vector be represented in component notation?</h3>

Given a magnitude M and angle \theta, then a vector V can be represented as follows in component notation:

V = (M\cos{\theta}, M\sin{\theta})

In this problem, the magnitude and the angle are given, respectively, by:

M = 12, \theta = 143^\circ

Hence:

V = [12cos(143º), 12sin(143º)] = (-9.58, 7,22).

Which means a displacement of 9.58 miles to the west(negative x = west) and 7.22 miles to the north(positive y = north).

The component form is of approximately (-9.58, 7,22). It means that the ship is about 9.58 miles to the west and about 7.22 miles to the north of where the ship left the port.
