Find the indicated length. find LM
Roman55 [17]

The overall length is given as 22.

The line is split into 2 parts X and 3X.

So we have X + 3X = 22

Add X and #X to get 4X:

4X = 22

Divide both sides by 4 to get X:

X = 22 /4

X = 5.5

Now we know what X is so now replace x with 5.5 and solve for LM:

LM = 3X = 3*5.5 = 16.5

Does anyone know the answer? Please and Thank you! Algebra
Over [174]

Answer:

Step-by-step explanation:

y = mx + b

we can see the slope is down hill,  so it's  negative

when the X is zero then it's 2

b = 2

slope is rise over run  2/3

y = -2/3x + 2

the slope is -2/3  (note the negative)

the y intercept is 2

What is the value of a?<br><br><br><br><br> 27.5<br><br><br> 45<br><br><br> 90<br><br><br> 50
Valentin [98]
90. The measure of an inscribed angle is half of that of the measure of its arc, and the measure of the angle corresponding with arc a is 45. 45*2 is 90, so 90 is the measure of arc a.

What are the solutions to the following system of equations? y = x2 + 3x − 7 3x − y = −2 (2 points) (3, 11) and (−3, −7) (11, 3)
Minchanka [31]
ANSWER

(3, 11) and (−3, −7)


EXPLANATION

The given system of equations are:


y =  {x}^{2}  + 3x - 7

and

3x - y =  - 2

or

y = 3x  + 2


We equate the two equations to obtain,



{x}^{2}  + 3x - 7 = 3x + 2

We rewrite in standard quadratic form to obtain,

{x}^{2}  + 3x  - 3x - 7 - 2 = 0


This simplifies to

{x}^{2}- 9= 0


We solve for x to obtain,


{x}^{2}  = 9

x =  \pm \sqrt{9}

x =  \pm 3

x = 3 \: or \: x =  - 3

When
x = 3

y = 3(3) + 2 = 11

When x=-3,

y = 3(  - 3) + 2 =  - 7


Therefore the solution for the system is (3, 11) and (−3, −7).
