-3x + y = -6 Y= 1/2x-1
julia-pushkina [17]

Answer:

Step-by-step explanation:

Given system of equations in the question are,

-3x + y = -6

y = \frac{1}{2}x-1

We can rewrite these equation as,

-3x + y = -6

y = 3x - 6 ------(1)

Table of input-output values for this equation will be,

x       0      1        2         3          4

y      -6     -3       0         3          6

y = \frac{1}{2}x-1 ------(2)

Table for this equation will be

x        0        2         4         6         8

y        -1        0         1          2         3

By plotting these points on the graph we find (2, 0) is a common point in both the tables,

Therefore, (2, 0) is the only one solution of the given system of equations.

Trava [24]
<span>In mathematics, volume is the amount of space occupied by an object measured in three dimensions, expressed in cubic units. It is simply the product of the area of the base times the height. We do as follows:

Volume = 1360 = Ah
1360 = 160h
h = 8.5 ft</span>
