Uma fabrica produz apenas camisetas e bolas. a primeira com custo de r$ 20,00 por unidade e a segunda com custo de r$15,00 por unidade. se chamamos de x a quantidade produzidas de camisetas e de y a quantidade produzida de bolas, qual sera a expressão algébrica do custo desses dois artigos? qual sera o custo se forem produzidas 300 e 500 unidades, respectivamente?

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

not sure but it may be b, as i said i'm not sure.
