Answer:

(x+2)(x-6), factors are -6 and 2

Step-by-step explanation:

x^2 − 4x − 12

we find out factors whose product is -12  and sum is -4

-6 times 2 = -12

-6+2=-4

So two factors are -6  and 2

Now we use the factors -6 and 2 to factor x^2 -4x-12

x^2 -6x+2x-12

(x^2 -6x)+(2x-12)

take out GCF, x(x-6) + 2(x-6)

(x+2)(x-6)

(x-6)(x+2)

When you foil it you get x^2+2x-6x-12
After you do this you then add like terms to get x^2-4x-12
Therefore the answer (x-6)(x+2) is correct.

Jessica brought a cooler to the family picnic filled with 32 cans of regular soda and 18 cans of diet soda. What is the ratio of
natta225 [31]

Answer:

ratio of regular to diet soda = 16/9

Step-by-step explanation:

Jessica brought a cooler to the family picnic filled with 32 cans of regular soda and 18 cans of diet soda. This means

Number of cans of regular soda = 32

Number of cans of diet soda = 18

Total number of soda brought to the family picnic = number of cans of regular soda + number of cans of diet soda

= 32 + 18= 50

the ratio of regular soda cans to diet cans in the cooler= 32/18

Divide numerator and demo minator by 2, we have 16/9.

The fraction cannot be reduced further. So ration of regular to diet soda = 16/9

Write the equation of the graph obtained when the graph of y=1/x is compressed vertically by a factor of 0.25, translated 4 unit
Shtirlitz [24]

Answer: The equation is y = 0.25/(x - 4) + 3

Step-by-step explanation:

If we have a function y = f(x)

A compression means that we multiply the function by a factor smaller than 1.

Then the vertical compression by a factor of 0.25 is:

y = 0.25*f(x)

a translation by A units to the right, means that we need to valuate the function in x - A.

So now we have:

y = 0.25*f(x - 4)

A translation in the y-axis means that we need to add a constant to the equation, then if we tralate it by 3 units up, we have:

y = 0.25*f(x - A) + 3

Then, if f(x) = 1/x

Our new equation is:

y = 0.25/(x - 4) + 3
