Answer:
y = 2/5x - 2
Step-by-step explanation:
Step 1: Write equation
2x - 5y = 10
Step 2: Solve for <em>y</em>
- Subtract 2x on both sides: -5y = 10 - 2x
- Divide both sides by -5: y = -2 + 2/5x
- Rewrite: y = 2/5x - 2
The correct answer for the problem above is -23 .
Explanation
1. collect the like terms
2x + x - 11 + 3 - 7x = 15
2x , x , & -7x are like terms
-11 & 3 are like terms
2x + x -7x = -4x
-11 + 3 = -8
2. Move constant to the right-hand side and change its sign .
-4x = 15 + 8
-4x = 23
3. Make the signs on both sides of the equation
-4x = 23 turning into 4x = -23
answer =
4x = -23
Use the property
(a -b)(a+ b) = a^2 - b^2
49x^2 - 81 = (7x + 9)((7x - 9)
Answer:
x > 28/3
Step-by-step explanation:
34 > 3(2 − x)
simplify the bracket
34 > 6 -3x
combine the like terms
34 - 6 > 3x
28 > 3x
divide by 3
x > 28/3
Sorry I don't know how to graph here, but I can graph it by writing the way it can be graphed.
It is in slope intercept form; y = mx + b
where mx is the slope and b is the y-intercept;
x>28/3; where 28/3 is the slope which means; at the y-intercept, go up 28 times and to the right 3 times
And b is 0; which means at 0 where the slope will be applied, go up 28 times and to the right 3 times.
Hope this helps!
Good luck.
