The school band is selling pizza for $7 each to raise money for new uniforms. The supplier charges $85 plus $4 per pizza. Write and solve an inequality to find the number of pizzas the band members must sell to make a profit.
a The band members must sell at least 28 pizzas.
b The band members must sell at most 29 pizzas.
c The band members must sell at most 28 pizzas.
d The band members must sell at least 29 pizzas.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

is should be y = 5x

step-by-step explanation:

correct me if im wrong

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

y + 11 = (1/4)(x + 16)
