Step-by-step explanation:

I won't be answering all of them because that's a lot, but I'll try and help you on how to do them.

So, factorising means you put the equation into brackets.

The easiest way to work these out would be to look at the pairs of numbers that multiply to make the last number in the equation (so for 2a: 1x2 is the only option, for 2b: 1x4, 2x2, 4x1 for 2c: 1x30, 2x15, 3x10, 5x6 etc)

The next step is to look at the pairs and see which ones could add or subtract to make the number in the middle of the equation

(So for 2a: 1+2=3, 2b: 1+4=5, 2c: 3+10=13)

Then put those numbers into the brackets, with the + or - that you just did

So 2a: (x+1)(x+2)

2b: (m+1)(m+4)

2c: (a+3)(a+10)

etc

F(x) = -3 +3

Mila [183]

Answer: Y

Step-by-step explanation:

Since f(x) passes through (0,3), its inverse should pass through (3,0).

This eliminates X and Z.

Also, since f(x) has a negative slope, so its inverse should also have a negative slope.

This eliminates W.

A cooler contains fifteen bottles of sports drink: eight lemon-lime flavored and seven orange flavored

dem82 [27]

Answer:

Mutually exclusive,

$P(\text{Lemon-lime or orange})=\frac{2}{3}$

Step-by-step explanation:

Please consider the complete question:

Determine if the scenario involves mutually exclusive or overlapping events. Then find the probability.

A cooler contains twelve bottles of sports drink: four lemon-lime flavored, four orange flavored, and four fruit-punch flavored. You randomly grab a bottle. It is a lemon-lime or an orange.

Let us find probability of finding one lemon lime drink.

$P(\text{Lemon-lime})=\frac{\text{Number of lemon lime drinks}}{\text{Total drinks}}$
