Mathematics
1 answer:
STatiana [176]4 years ago
4 0

Answer:

8. 6 shirts ($61)

9. $61

10. 32 shirts (256)

Step-by-step explanation:

To get the answers you could either graph the rates or create a table. Creating a table is easier to understand, graphing is much faster. I attached pictures of the graphs. Y axis being amount of $ and x axis being the amount of shirts.

Second graph is for questions 8 and 9

first graph for question 10

The difference is that i took out shipping for question 10

Table explains 8 and 9 more easily

2x - 3y = 1 and x + 2y = 18​
Yuliya22 [10]

Answer:

x = 8 and y = 5

Step-by-step explanation:

2x - 3y = 1 --(1)

x + 2y = 18

x = 18 - 2y --(2)

sub (2) into (1):

2(18 - 2y) - 3y = 1

36 - 4y - 3y = 1

-7y = 1 -36

7y = 35

y = 5

x = 18 - 2(5) = 8

Factor quadratic trinomials 27x^2-90x+27
igor_vitrenko [27]
27x^2-81x-9x+27      In this case, just in your mind multiply 27 (coefficient of x^2) by the constant value 27(the end value of the quadratic trinomial). Then find factors that give you the value -90 when you add and 729 (27*27) when you multiply.

Factorise the values
 27x( x-3)-9(x-3)

Which will give you

(27x-9)(x-3)
