Answer:
1.7j - 3.4 = 1.7(j - 2)
Step-by-step explanation:
Note that both 1.7 and -3.4 are evenly divisible by 1.7:
1.7j - 3.4 = 1.7(j - 2)
Convert them all to 10 in the denominator.
4/10, 5/10, 1/10, 2/10, 4/10
Now which ones are greater than 2/5?
5/10 only.
Answer:
Then the answer to the system is the point (-1, 3)
which corresponds to x = -1 and y = 3
Step-by-step explanation:
Start by dividing the first equation by 3 on both sides, and get:
x + y = 2
now multiply it by 5 in order to be able to eliminate the term in y in the combining of both equations:
5 x + 5 y = 10
+
9 x - 5 y = - 24
___________
14 x + 0 = -14
solve for x by dividing both sides by 14:
x = -14/14 = -1
Use the x = -1 answer in the equation 3 x + 3 y = 6 and solve for y:
-3 + 3 y = 6
add 3 on both sides:
3 y = 9
divide both sides by 3 to isolate y:
y = 3
Then the answer to the system is the point on the plane (-1, 3)
which corresponds to x = -1 and y = 3
The answer is B because the first number in those points don’t repeat but all the other ones have the first number repeating
Answer:
-40
Step-by-step explanation:
-25 -(-5) + (-20)
-25 + 5 - 20
-20 - 20
= - 40
Note that:
+ ( + ) = +
+ ( - ) = -
- ( + ) = -
- ( - ) = +
