What is the value of x?

MariettaO [177]

x = 36.2 .
______________________________________________

Explanation:
________________________________________________
2x - 1 + 3x = 180 ;

Combine the "like terms" on the left-hand side of the equation:
________________________________________________
+2x + 3x = + 5x ;
_____________________________________
And rewrite:
_____________________________________
5x - 1 = 180 ;
_____________________________________
Add "1" to each side of the equation:
_____________________________________
5x - 1 + 1 = 180 + 1 ;
_____________________________________
5x = 181 ;
_____________________________________
Divide EACH SIDE of the equation by "5" ;
_____________________________________
5x / 5 = 181 / 5 ;
_____________________________________
to get:
_____________________________________
x = 36.2 .

PLZ I WILL PUT YOU AS BRAINYEST 29<(m^2+9)/2<45

denis23 [38]

Answer:

M=4

Step-by-step explanation:

29-25=4

M to the second = 16

16 + 9 = 25

That’s where the 25 comes from

Using the socratyne theorem this problem is easily solved as you see above.

With the 25, m = 4

Answer this question

Answer: OPTION B.

Step-by-step explanation:

We have the following functions f(x) and g(x):

$f(x)=x^2-2x-8\\\\g(x)=\frac{1}{4}x-1$

In order to find for which values of "x" $f(x)=g(x)$ , we can check each option given:

<u>OPTION A</u>

Substitute $x=-1.75$ into the function f(x) and evaluate:

$f(-1.75)=(-1.75)^2-2(-1.75)-8=-1.4375$

Substitute $x=-1.75$ into the function g(x) and evaluate:

$g(-1.75)=\frac{1}{4}(-1.75)-1=-1.4375$

Substitute $x=-1.438$ into the function f(x) and evaluate:

$f(-1.438)=(-1.438)^2-2(-1.438)-8=-3.0561$

Substitute $x=-1.438$ into the function g(x) and evaluate:

$g(-1.438)=\frac{1}{4}(-1.438)-1=-1.3595$

This is not the correct option.

<u>OPTION B</u>

We already know that:

$f(-1.75)=-1.4375$

$g(-1.75)=-1.4375$

Substitute $x=4$ into the function f(x) and evaluate:

$f(4)=(4)^2-2(4)-8=0$

Substitute $x=4$ into the function g(x) and evaluate:

$g(4)=\frac{1}{4}(4)-1=0$

<em> This is the correct option.</em>

<u>OPTION C</u>

We already know that:

$f(-1.438)=-3.0561$

$g(-1.438)=-1.3595$

Therefore, this is not the correct option.

<u>OPTION D</u>

We already know that:

$f(4)=0$

$g(4)=0$

Substitute $x=0$ into the function f(x) and evaluate:

$f(0)=(0)^2-2(0)-8=-8$

Substitute $x=0$ into the function g(x) and evaluate:

$g(0)=\frac{1}{4}(0)-1=-1$

This is not the correct option.
