Answer:

(-2,-5)

Step-by-step explanation:

y = 2x-1

3x-y = -1

We can use substitution

3x - (2x-1) = -1

Distribute the minus sign

3x -2x+1 = -1

x +1 =-1

Subtract 1 from each side

x+1-1 = -1-1

x=-2

Now we need to find y

y = 2x-1

y = 2(-2) -1

y = -4-1

y = -5

(-2,-5)

Answer:

x= -43 or x=57

Step-by-step explanation:

Apply absolute value rule: If |u|=a, a>0 then u=a or u=-a

So applying that to our equation:

|x-7|=50, x-7 can either equal +50 or -50 so we solve for both

x-7= -50 ---> x= -43

x-7=50 ---> x=57

I hope this helps!

The map shows the length (in miles) of shoreline along the Gulf of Mexica for each state that borders the body of water. What is

Jet001 [13]

Answer:

TX: 0.23

LA: 0.24

MS: 0.03

AL: 0.03

FL: 0.47

Step-by-step explanation:

In the figure attached, the map is shown.

Total length of the shoreline: 367 + 397 + 44 + 53 + 770 = 1631 miles

probability of the ship landing in Texas: 367/1631 = 0.23

probability of the ship landing in Louisiana: 397/1631 = 0.24

probability of the ship landing in Mississippi: 44/1631 = 0.03

probability of the ship landing in Alabama: 53/1631 = 0.03

probability of the ship landing in Florida: 770/1631 = 0.47
