Solve the equation by factoring: x2 − 7x + 12 = 0
Gnoma [55]

Answer:

x = 3 . . . or . . . x = 4

Step-by-step explanation:

The factored form is ...

(x -3)(x -4) = 0

The zero product rule tells you the solutions are the values of x that make the factors be zero:

x = 3

x = 4

_____

Comment on factoring

When the leading coefficient is 1, the coefficient of the x-term is the sum of the constants in the binomial factors, and the constant term is their product. You can see this by multiplying out the generic case:

(x +a)(x +b) = x^2 +(a+b)x + ab

What this means is that when you're factoring, you're looking for factors of the constant that add up to give the coefficient of the x-term. Here, the x-term is negative and the constant is positive, so both factors will be negative.

12 = -1×-12 = -2×-6 = -3×-4

The sums of these factor pairs are -13, -8, -7. Clearly, the last pair of factors of 12 will be useful to us, since that sum is -7. So, the binomial factors of our equation are ...

(x -3)(x -4) = 0

___

If the leading coefficient is not zero, the method of factoring is similar, but slightly different. Numerous videos and web sites discuss the method(s).

Matthew accepted a new job at a company with a contract guaranteeing annual
guajiro [1.7K]

Answer:

S= 4000n+50000

Step-by-step explanation:                       Table

50000+4000=54000                         0           5000

54000+4000=58000                         1            54000

58000+4000=62000 etc..                2            58000

                                                            3           62000

Is increasing by 4000  and thats the rate of change so S=4000n

And the y intercept always will be with a 0 in the cordinates and the only with a 0 is 50000.

We put all together and it will be

Answer: S=4000n+50000

I need help ASAP!!!!!!!!!!!!!
Ede4ka [16]
The first question is 50% because a total of 30 girls bought lunches out of 60 kids

the second question, the easiest way is to plug in the x and y coordinates
3(4) - 2(0) = 12
12-0=12
12=12
because 12 = 12 is true, the first pair is the answer
