What is the solution to this equation x/5=25

amid [387]

Answer:

x = 125

Step-by-step explanation:

Given

$\frac{x}{5}$ = 25

Multiply both sides by 5 to clear the fraction

x = 5 × 25 = 125

x = 125

Factor this expression completely and then place the factors in the proper location on the grid. Note:

Eddi Din [679]

First we are going to group the terms that contains the common factor $m$ in one parenthesis, and the other ones in another parenthesis:
$mn-4m-5n+20$
$(mn-4m)-(5n+20)$
Notice that our the terms in our first parenthesis have a common factor $m$ , and the terms in our second one have the common factor $5$ . Lets factor those out:
$m(n-4)-5(n-4)$
Now we have a common factor $(n-4)$ in both terms, so we can factor those out as well:
$(n-4)(m-5)$

We can conclude that the completely factored expression ordered alphabetically is $(m-5)(n-4)$ .

Help is it A or B? pls help

Damm [24]

Answer:

$f(x)=-(x+8)(x-2)$

Step-by-step explanation:

Start by factoring out a -1...

$f(x)=-(x^2+6x-16)$

Now, we have to find two integers that multiply to get -16 and have a sum of 6:

(-2)*8=-16

-2+8=8-2=6

Using this, we can split 6x into -2x and 8x...

$f(x)=-(x^2-2x+8x+16)$

Factor the first and second half separately...

$f(x)=-[(x^2-2x)+(8x-16)]\\f(x)=-[x(x-2)+8(x-2)]\\$

Since both x and 8 are being multiplied by x-2, we can combine them to get...

$f(x)=-(x+8)(x-2)$

If the x-value repeats and the y does not, is it a function?

kogti [31]

Answer:

If X repeats and y does not it is not an example of a function. But if the y repeats and has two different x values that can be known as a function.

For an example ( 1 , 3) and (1, 4) thats not an example of a function because the x value is repeating but if its ( 1, 4) and (2,4) a thats

a function because no x value is repeating the x value is known as an independent value. Does that make sense?

"This relation is definitely a function because every x-value is unique and is associated with only one value of y. So for a quick summary, if you see any duplicates or repetitions in the x-values, the relation is not a function."
