Translation: a) you can make a building like this with 5 layers how many blocks do you need? and with 6layer?
b) how many layers does the building have that is made of 165 blocks?

take reference from the picture

positive

step-by-step explanation:

the quadrant is facing upwards

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

thats one

step-by-step explanation:

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.
