Answer:
x = - 3, y = 4
Step-by-step explanation:
Given the 2 equations
- 2x + y = 10 → (1)
y = -
x + 3 → (2)
Substitute (2) into (1), that is
- 2x -
x + 3 = 10 ( multiply through by 3 to clear the fraction )
- 6x - x + 9 = 30
- 7x + 9 = 30 ( subtract 9 from both sides )
- 7x = 21 ( divide both sides by - 7 )
x = - 3
Substitute x = - 3 into (2) for corresponding value of y
y = -
(- 3) + 3 = 1 + 3 = 4
solution is x = - 3, y = 4
I think you are suppose to get "k" by itself, so you first multiply 2/5 to (k - 2)
-8 ≤ 2/5 (k - 2)
-8 ≤ 2/5k - 4/5
Next you add 4/5 on both sides
-8 + 4/5 ≤ 2/5k
Then you make the denominators the same in order to add them
-40/5 + 4/5 ≤ 2/5k
-36/5 ≤ 2/5k
Finally you multiply each side by 5/2 to get "k" by itself
-18 ≤ k
Answer:
A because if you solve for x then it becomes x<5. So obviously x has to be less than 5, and since you can not have a decimal of a tablet, the answer is 4.
Step-by-step explanation:
Answer:
The slope is 0.
Step-by-step explanation:
You could draw it on graphs paper . It will be a horizontal line passing through the point (0,4). y will always be 4 and x can be any value.
The slope of a horizontal line is 0.
