Answer:

The answer is 0.

Step-by-step explanation:

<u>Question</u> :

{\implies{\small{\tt{\bigg\{\Big(15 \times 115 - ( - 3)\Big) \bigg\} \bigg(4 - 4 \bigg) \div 3 \bigg\{\Big(5 + ( - 3) \times ( - 6)\Big)\bigg\}}}}}

<u>Solution</u> :

{\implies{\small{\tt{\bigg\{\Big(15 \times 115 - ( - 3)\Big) \bigg\} \bigg(4 - 4 \bigg) \div 3 \bigg\{\Big(5 + ( - 3) \times ( - 6)\Big)\bigg\}}}}}

{\implies{\small{\tt{\bigg\{\Big(1725 - ( - 3)\Big) \bigg\} \bigg(4 - 4 \bigg) \div 3 \bigg\{\Big(5 + ( - 3 \times  - 6)\Big)\bigg\}}}}}

{\implies{\small{\tt{\bigg\{\Big(1725  +  3\Big) \bigg\} \Big( \: 0 \:\Big) \div 3 \bigg\{\Big(5 + 18\Big)\bigg\}}}}}

{\implies{\small{\tt{\bigg\{\Big(1728\Big) \bigg\}  \: 0 \div 3 \:  \bigg\{\Big(13\Big)\bigg\}}}}}

{\implies{\small{\tt{\Big\{1728\Big\}  \: 0 \: \Big\{13\Big\}}}}}

{\implies{\small{\tt{1728  \times 0  \times 13}}}}

{\implies{\small{\tt{1728 \times 0}}}}

{\implies{\small{\tt{\underline{\underline{0}}}}}}

Hence, the answer is 0.

Factor completely 3x^2+2x-1
Morgarella [4.7K]

Answer:

(3x - 1)(x + 1)

Step-by-step explanation:

3x^2 factors into 3x and x.

-1 factors into -1 and 1.

Now we try different positions of 3x, x, -1, and 1 until we find the correct factorization.

Try: (3x - 1)(x + 1)

When you multiply the two factors together, the middle term will be 3x - x = 2x

Since 2x is the original middle term, this is the correct factorization.

Answer: (3x - 1)(x + 1)

Find the 75th term of the arithmetic sequence -17, -13, -9....
Sphinxa [80]

Answer:

The 75th term of the arithmetic sequence -17, -13, -9.... is:

a_{75}=279

Step-by-step explanation:

Given the sequence

-17, -13, -9....

An arithmetic sequence has a constant difference 'd' and is defined by  

a_n=a_1+\left(n-1\right)d

computing the differences of all the adjacent terms

-13-\left(-17\right)=4,\:\quad \:-9-\left(-13\right)=4

The difference between all the adjacent terms is the same and equal to

d=4

The first element of the sequence is:

a_1=-17

now substitute d=4 and a_1=-17 in the nth term of the sequence

a_n=a_1+\left(n-1\right)d

a_n=4\left(n-1\right)-17

a_n=4n-21

Now, substitute n = 75 in the a_n=4n-21 sequence to determine the 75th sequence

a_n=4n-21

a_{75}=4\left(75\right)-21

a_{75}=300-21

a_{75}=279

Therefore,  the 75th term of the arithmetic sequence -17, -13, -9.... is:

a_{75}=279

Write y=-5/8x+3 in standard form using integers?
Ivenika [448]

Answer:

standard form of given equation is 5x - 8y = -3

Step-by-step explanation:

y= \frac{5}{8}x + 3

Standard form of linear equation is Ax + By = C

First we remove the denominator 8

We multiply the whole equation by 8

So equation becomes

8y = 5x + 3

Now we move 5x to the left hand side, we subtract 5x on both sides

-5x + 8y = 3

Now we remove the negative side from -5x  by dividing the whole equation by -1

5x - 8y = -3
