Zeros of the function are -5 and 6.

<u>Step-by-step explanation:</u>

f(x) = x² - x - 30

Step 1:

Factorize the equation using Product and Sum method. Product = - 30 and Sum = - 1

⇒ f(x) = x² - 6x + 5x - 30

Step 2:

Solve the equation by equating the function to zero to find zeros.

⇒ x (x - 6) + 5(x - 6) = 0

⇒ (x - 6)(x + 5) = 0

⇒ x = 6, - 5

What is the opposite of the number 14​
lidiya [134]

Answer:

The opposite of 14 is -14.

Step-by-step explanation:

Opposites are numbers with the same distance from 0 but one is to the right of 0 and the other is to the left of 0.

The opposite of 0 is itself,0.

So the opposite of 5 is -5 since both 5 and -5 have the same distance from 0 and one is to the left and one is to the right of 0.

The opposite of 14 is -14 since both have the same distance from 0 and one is to the right and one is to the left of 0.

You can also think of this question as what can I add to 14 that will give me 0.

The answer is -14 since -14+14=0.

Another word for opposites is additive inverses.  When you add additive inverses you get 0.

Another example: What is the opposite of -16?  

The answer is 16 since 16+(-16)=0.

Which number can each term of the equation be multiplied by to eliminate the fractions before solving?
AVprozaik [17]

Answer:

The correct answer is Option 4: 12

Step-by-step explanation:

Given equation is:

6-\frac{3}{4}x+\frac{1}{3} = \frac{1}{2}x+5

We have to find a number that is common multiple of all the denominators or least common divisor

So to find the LCM

The numbers in denominator are: 4,3,2

So,

4=> 4,8,12,16\\3 => 3,6,9,12,15\\2=> 2,4,6,8,10,12

It can clearly be seen that 12 is the LCM of all three numbers so the equation will be multiplied with 12 to eliminate the fractions.

12*6-12*\frac{3}{4}x+12*\frac{1}{3} =12* \frac{1}{2}x+12*5\\72-9x+4 = 6x+60

Hence,

The correct answer is Option 4: 12

Identify holes in the graph of the function.
snow_lady [41]

Answer:     x = 0

Step-by-step explanation:

The hole in the graph (a discontinuity) exist where the function doesn't exist. Because anything divided by zero is undefined, then the function would not exit at 0, thus having a hole/discontinuity.
