<span>−8x+7y=25 is already in standard form, altho some people would prefer to re-write it as

</span><span>−8x+7y-25 = 0.

You have shared 4 equations here.  Next time, please separate them with commas or semi colons, or type just 1 equation per line, for increased clarity.  Thanks.</span>

<em>Translate into an algebraic equation:-</em>

<em>The quotient of a number and 5.</em>

<em />

<em />\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}

✳︎ First, the word "quotient" indicates that we divide.

Here, we have the quotient of a number and 5, so we divide the number by 5; let the number be d.

So the quotient of d and 5 looks as follows:-

\bold{\dfrac{f}{5}}

<h3>Good luck with your studies.</h3>

castortr0y [4]

Answer:

M(M + 3) = 108

The two numbers would be represented as m and m+3 to show the 3 units apart. So when multiplied, it looks like m times m+3

vodomira [7]

Answer:

See below in bold.

Step-by-step explanation:

1.  x/8 = 15/24

Cross multiplying:

24x = 8*15

x = (8*15)/24

x = 5.

2.   5/6 = 35/x

5x = 6*35

5x = 210

x = 210/5

x = 42.

3.<em>  </em>18/42

Divide top and bottom by 6:

18 / 6 / 42/6

= 3/7.

4.  15/75

Divide top and bottom by 15:

= 1/5.

If a polynomial function f(x) has roots 3 and StartRoot 7 EndRoot, what must also be a root of f(x)?
Ivenika [448]

Answer:

–√(7) must also be a root of f(x)

Step-by-step explanation:

Given that the roots of an equation is 3 and √(7). This means that x = 3 or √(7). Therefore, the function is definitely going to be:

f(x) = (x – 3)(x² – 7)

This is because we are dealing with √(7) and what brought about √(7) was x² = 7.

If this is the case, we know that x² = 7 will give

x = ±√(7)

Hence, our roots are x = 3 or √(7) or –√(7). Therefore, –√(7) must also be a root of f(x).
