Question:

Expand and simplify 5(x - 1) - 3(x + 4)

Answer:

1.) Use the distributive property to solve this equation:

5(x - 1) = 5x - 5

3(x + 4) = 3x + 12

2.) Put it in the equation:

5x - 5 - 3x + 12

3.) Group them:

5x - 3x - 5 + 12

4.) Simplify:

2x - 7
which is the answer.

Hope this helped! :))

So first it’s 5x-5-3x-12( got this using distributive property)
Now we simplify by combining like terms so 5x-3x=2x
And -5-12=-17
Ending to be 2x-17

135 in percentage out of 100% is 1.35%
To Check This Answer
in 135(135.) move the decimal twice to the left and it becomes 1.35 you then multiply that by 100 and it will give you 135. Therefore 1.35 will become a percent which is 1.35%

How do I obtain the real number solutions to the polynomial function f(x)=x^3 - 4x^2 + x +6?

Svetlanka [38]

$\bf f(x)=x^3-4x^2+x+6\\\\
-----------------------------\\\\

\begin{array}{l|lrrrrllllll}
3&&1&-4&1&6\\
&&&3&-3&-6\\
--&&--&--&--&--\\
&&1&-1&-2&0
\end{array}\impliedby x=3\implies (x-3)=0
\\\\\\
\textit{that give us the factors of }
\\\\\\
f(x)=(x-3)(x^2-x-2)\impliedby \textit{factoring the quadratic, we get}
\\\\\\
f(x)=(x-3)(x-2)(x+1)\impliedby \textit{setting f(x) to 0}
\\\\\\
0=(x-3)(x-2)(x+1)\implies 
\begin{cases}
x-3=0\to &x=3\\
x-2=0\to &x=2\\
x+1=0\to &x=-1
\end{cases}$

so.... notice, using the p/q factors, we ended up using 3/1 or just 3, so the root of x = 3, which gives us the factor of x-3 then

then you factor the quadratic, then set f(x) to 0, and solve each for "x"

What is 12/60 expressed in lowest terms 1/4 1/8 1/6 1/5

Ahat [919]

1/5 because you divide them both equally by 2 and then by 2 and then by 3 and you get 1 and 5. :)

Help please 100 point

ZanzabumX [31]

Answer:

Solution given:

we have

<A+<B=exterior <C[sum of two opposite interior angle of a triangle is equal to the exterior angle in a triangle]

So

3x-13+ 2x+4=116°

5x-9=116°

5x=116°+9°

x=125/5

x=25

Now

<A=3×25-13=62°

<B=2×25+4=54°

Please help, any help is appriciated :)

Answer:

(a) |ab| if a<0 and b>0

since the modulus of a number no matter whether it is positive or negative gives the result as a positive number.

if a<0 and b>0 then ab<0

this implies ab is a negative number and modulus of negative number comes out to be positive term.

eg: if a= -2 and b=3

Then ab= -6

and |ab|=|-6|=6

(b) |ab| if a>0 and b>0.

since both a and b are positive numbers i.e. strictly greater than zero.

hence, ab>0

eg: if a=5 and b=2

then ab=10

and |ab|=|10|=10
