What is the X input if Its (1,5) (2,12) (3,19) (X,26) what is X?

x=4

Step-by-step explanation:

the rule is for each time x is increased by one y increases by 7

like 5+7=12

12+7=19

19+7=26

so

1+1=2

2+1=3

3+1=4

4 is the answer

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
