3y-15-6x in slope intercept form
ASHA 777 [7]
When you think of slope intercept form we think of Y=mx+b
m=slope and b = intercept

So all you do is solve for Y in your given equation.

Im going to guess the equal sign  because you didn't include it. I can fix the answer is I was wrong.

3y-15=6x    (add 15 to both sides)

3y=6x+15 (divide by 3)

y=2x+3 (final answer)

2/0 = 32/48 = 30/0. What number shpuld come in place of the zeros?​
Anton [14]

Answer:

\sf \dfrac{2}{3}  = \dfrac{32}{48}  = \dfrac{30}{45}

<h3><u>For the 1st part</u></h3>

\sf \rightarrow \dfrac{2}{x} = \dfrac{32}{48}

\sf \rightarrow 2(48)= {32x}

\sf \rightarrow 32x= 96

\sf \rightarrow x = 3

<h3><u>For the 2nd part</u></h3>

<u />\rightarrow \sf \dfrac{32}{48} = \dfrac{30}{y}

\rightarrow \sf {32y} = 30(48)

\rightarrow \sf {32y} = 1440

\rightarrow \sf y = 45

Find cube root of 175616 ??​
Tpy6a [65]

Answer:

56

Step-by-step explanation:

Cube root of 175616 by prime factorization method is 56

Solution:

To find cube root of 175616 by prime factorization method

A number that must be multiplied by itself three times to equal a given number is called cube root

Prime factorization method:

Prime factorization is a number written as the product of all its prime factors.

In order of finding cube root by prime factorization we use the following steps:

Step I : Obtain the given number

Step II : Resolve it into prime factors.

Step III : Group the factors in 3 in such a way that each number of the group is same

Step IV : Take one factor from each group

Step V : Find the product of the factors obtained in step IV. This product is the required cube root

Prime factorization of 175616:

\text{ prime factors of 175616 } = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 7 \times 7 \times 7 prime factors of 175616 =2×2×2×2×2×2×2×2×2×7×7×7

Thus we get,

\sqrt[3]{175616} = \sqrt[3]{2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 7 \times 7 \times 7}

3

175616

=

3

2×2×2×2×2×2×2×2×2×7×7×7

Make the groups of 3 of equal numbers

\sqrt[3]{175616} = \sqrt[3]{2 \times 2 \times 2} \times \sqrt[3]{2 \times 2 \times 2 \times } \times \sqrt[3]{2 \times 2 \times 2} \times \sqrt[3]{7 \times 7 \times 7}

3

175616

=

3

2×2×2

×

3

2×2×2×

×

3

2×2×2

×

3

7×7×7

So there are 4 equal groups. So from that group take one factor out

\sqrt[3]{175616} = 2 \times 2 \times 2 \times 7 = 56

3

175616

=2×2×2×7=56

Thus Cube root of 175616 by prime factorization method is 56
