kirill [66]
Use elimination
Multiply first equation by 4
12a - 8b = 56
12a + 9b = 39
Subtract both
-17b = 17
b = -1
Plug in -1 for b
3a - 2(-1) = 14
3a = 12, a = 4
Final answer: a = 4, b = -1

One type of plant root splits 4 times while growing in the ground. The number of new roots after each split can be modeled by th
notsponge [240]

Answer:

All positive integers less than or equal to 4

Step-by-step explanation:

The domain of the function are all possible values which variable x can take.

Since x is the number of times the root splits, x can take values 1 (1 time splits), 2 (2 times splits), 3 (3 times splits), 4 (4 times splits).

The variable x cannot take negative values because it cannot split -2 times.

The variable x cannot take integer values greater than 4, because this type of plant root splits 4 times while growing in the ground.

Hence, the domain of the function f(x) is all positive integers less than or equal to 4.

The manufacturer of banjos spends $250 to make each banjo and sells them for $400. The manufacturer also has fixed costs each mo
raketka [301]

Answer:

The cost for making x banjos is c = $ 400 x

Step-by-step explanation:

Given as :

The making cost of each banjos = $ 250

The selling cost of each banjo = $ 400

Let The cost for making x banjos = c

Now,

∵ For making 1 banjos , the making cost = $ 250

∴  For making x banjos , the making cost = $ 250 × x

Again,

∵ The selling price of 1 banjos = $ 400

∴ The selling price of x banjos = = $ 400 × x

Hence The cost for making x banjos is c = $ 400 x . Answer
