Based on my calculation i know for sure F
would equal 10
Answer:
x<5/2
Step-by-step explanation:
We have
2x−3<2
Add 3 to both sides.
2x−3 +3 <2 +3
which makes
2x<5
Divide both sides by 2.
2x/2 < 5/2
x<5/2
Answer:
x=3
Step-by-step explanation:
x^2=9
x=3
Our matrix C is the encoder. Let X be our secret message and let B be our encoded message. Therefore the relationship between the 3 can be represented as:
CX = B
So we want to solve for X (our secret message). So using matrix algebra:
X = C^-1*B
where C^-1 is the inverse of C.
C^-1 = | 3 -2 |
|4 -3 |
So we take C^-1 and multiply it by matrix B to get X. Matrix B is already given to us. So just multiply those two. I used a calculator to get:
X = | 20 8 5 3 15 12 15 |
| 18 9 19 2 12 21 5 |
And since A = 1, B = 2, C = 3, etc....
We decode our message and it says:
X = | T H E C O L O |
| R I S B L U E |
So the answer is: The color is blue (D)
Answer:
Step-by-step explanation:
To graph this equation, start by plugging in different numbers for X and solve for Y.
For example: When x=0, y=0+3 ⇒ the coordinate is (0,3)
When x=1, y=1+3 ⇒ (1,4)
If you do this enough times, dotting each new coordinate then connecting them in a straight line, you will get your graph.
