For this case we have the following expression:
 (x-1) / (3) = k
 Substituting the value of k = 3 we have:
 (x-1) / (3) = 3
 From here, we must clear the value of x.
 We have then:
 x-1 = 3 * 3
 x-1 = 9
 x = 9 + 1
 x = 10
 Answer:
 
The value of x is given by:
 
x = 10

Which vertex will result in the maximum value of the function T = x – 3y?
exis [7]

Answer:

(0,-3) will give the maximum value

Step-by-step explanation:

To know the vertex, we have to substitute the coordinates in the options

we have this as follows

a) (1.5,0)

T = 1.5-3(0) = -1.5

b) (3.5,4)

T = 3.5 - 1)4)

= 3.5 - 4 = -0.5

c) (0,-3)

we have

T = 0-3(-3) = 0 + 9 = 9

d) (0,4)

we have this as:

T = 0 - 3(4) = -12

What’s the solution of y= 3x-1 and y= 3x+4
julia-pushkina [17]

Step-by-step explanation:

solution ? you mean where both lines cross each other ?

these are 2 parallel lines (same slope, but different y-intercept), so they never cross each other.

there is no solution.

formally :

3x - 1 = 3x + 4

-1 = 4

this is wrong. therefore there is no solution.
