Find LM. 2x-16 x-9 11 L M N

Mathematics
1 answer:
katrin [286]3 years ago
4 0

Answer:

LM is 8

Step-by-step explanation:

LM --> (2x-16)+(x-9) =11

Solve for x

  • 2x+x-16-9 =11
  • 3x-25=11
  • 3x=36
  • x=12

Plug in this value for LM equation to solve for LM:

  • (2x-16)
  • 2(12)-16
  • 24-16 = 8

LM is 8

The table shows some values of f(x) and g(x) for different values of x:
Brilliant_brown [7]
<h2>Answer:</h2>

C. x=2

<h2>Step-by-step explanation:</h2>

To complete the table, let's plug in the x-values into f(x) and g(x), so:

For f(x):

If \ x=0: \\ \\ f(0)=9(0)+7=7 \\ \\ \\ If \ x=1: \\ \\ f(1)=9(1)+7=16 \\ \\ \\ If \ x=2: \\ \\ f(2)=9(2)+7=25

For g(x):

If \ x=-2: \\ \\ g(-2)=5^{-2}=0.04 \\ \\ \\ If \ x=-1: \\ \\ g(-1)=5^{-1}=0.2 \\ \\ \\ If \ x=2: \\ \\ g(2)=5^{2}=25

From this, the complete table is:

\left|\begin{array}{c|c|c}x & f(x)=9x+7 & g(x)=5^{x}\\-2 & -11 & 0.04\\-1 & -2 & 0.2\\0 & 7 & 1\\1 & 16 & 5\\2 & 25 & 25\end{array}\right|

From the table, you can see that f(x)=g(x)=25 when x=2 so the correct option is C. x=2. But what does x=2 mean? It means that at this x-value, the graph of the linear function f(x) and the graph of the exponential function g(x) intersect and the point of intersection is (2,25)

What does she need to score on the fifth teat to get exactly a mean of 90?
loris [4]
I think I can bravely ignore the Freudian slip and solve this one.

-- If the mean of 5 tests is 90, then all 5 scores add up to (5 x 90) = 450

-- The sum of her first 4 scores is (95+ 90 + 85 + 95) = 365

-- If she has one more test to average 90, then she needs
to score (450 - 365) = <u>85</u> on it.

That looks like choice 'G '.

Klio2033 [76]

Answer:

C. | v -21 | \leq  0.15

Step-by-step explanation:

Because the volume is either 0.15 more or 0.15 less than 21 ounces. | v - 21 | indicate the difference between the volume and 21 and it has to be less than 0.15. Therefore answer C.

What is the value of 9 in the number 59.533
hoa [83]
First you have to label the other number , example : Ones, Tens, Hundreds
_______________________________________________________

5 9 . 5 3 3      | Start at the end , the number 3 , So it's 3= Ones , 3 , Tens , 5= Hundreds , There is a decimal so start over =  9= Ones 

The number Nine is just 9 , because it's in the ones place and if it's in the ones place most of the time it stays the same.

___________________________________________________

I really hope that my solutions and example helped you a lot , have a nice day :)
