Answer:
1 over 8
Step-by-step explanation:
let h be the number of hours then
A → C = 150h + 250 ( where C is charge )
B → C = 175h + 150
for 26 hours
A → C = (150 × 26 ) + 250 = 3900 + 250 = $4150
B → C = (175 × 26 ) + 150 = 4550 + 150 = $4700
Attorney A is cheaper for 26 hours, thus better deal
Equate the 2 equations to find hours they charge the same
175h + 150 = 150h + 250 ( subtract 150h from both sides )
25h + 150 = 250 ( subtract 150 from both sides )
25h = 100 ( divide both sides by 25 )
h = 4 ← number of hours when charges for both are equal
Thus Attorney A becomes a better deal at 5 hours
Answer: 1.25
Step-by-step explanation:
Answer:
y + 3 = (-1/2) x
Step-by-step explanation:
2x-y=-7
-y=-2x-7
y=2x+7
Slope m1= 2, perpendicular slope m2= -1/2
Equation of a line with perpendicular slope m2 and a point (0,-3) is
y - (-3) = (-1/2)(x - 0)
y + 3 = (-1/2) x
2y + 6 = - x
