Put the first equation in slope-intercept form, or y = mx + b. Start by subtracting y from both sides.
2x - y = -10, subtract 2x from both sides.
-y = -10 - 2x
Divide both sides by negative one.
y = 10 + 2x
To find the slope when the equations are in slope-intercept form you look at the coefficient of x. The first equation has the slope of 2 (which we just found), and the second equation has the slope of -2.
Parallel lines have the same slope and perpendicular lines have opposite reciprocal slopes. Since 2 and -2 are neither of these, your answer is neither.
The answer to <span>H+12.5=-12.5</span> is H=-25
Answer:
6x^3+11x^2-14x+12
Step-by-step explanation:
We just simply add like terms (terms with same power of x):
Like terms are in brackets now
So you just simplify now to give you:
Answer:
store a
Step-by-step explanation:
Store A: 25% off on $80 is $20, so the sneakers would be $60. Take 10% of $60 to get $6 off. The sneakers at Store A would cost $60 - $6 = $54. Store B: 20% off on $80 is $16, so the sneakers would be $64. Take 15% of $64 to get $9.60 off. The sneakers at Store B would cost $64 - $9.60 = $54.40.
