Answer:

8(11+x) = 123,

Where, x = unknown number

Step-by-step explanation:

Let x be the unknown number,

Since, Sum of 11 and x = 11 + x

Eight times of the sum of 11 and x = 8 × sum of 11 and x

= 8(11 + x)

According to the question,

Eight times of the sum of 11 and x = 123

⇒ 8(11+x) = 123

Which is the required equation.

Step-by-step explanation:

Given the table:

Month              f(x) = Number of imports    g(x) = Number of exports

January (1)                3                                                1

February (2)             4                                                3

March (3)                  5                                                5

April (4)                     6                                                7

From the table, it is clear that:

Number of imports = number of month + 2

so

also

Number of exports  = 2(number of month) + 1

so

Therefore, the number of imports equals the number of months plus one. i.e., which is a linear function.

If we compare it with the slope-intercept form of the line

Then,

slope = m = 1

y-intercept = 2

Also number of exports equals is also a linear function.

i.e.  

Here,

slope = m = 2

y-intercept = -1
