on the shape to the right angle k looks similar to angle p and we know angle p is accute making it less than 90
Answer:
The solution set is = {7, 9}.
Step-by-step explanation:
√(6x - 38) = x - 5
Square both sides:
6x - 38 = (x - 5)^2
x^2 - 10x + 25 - 6x + 38 = 0
x^2 - 16x + 63 = 0
(x - 7)(x - 9) = 0
x = 7, 9.
Check these solutions:
x = 7:
√(6x - 38) = √(42-38) = 2 and 7 - 5 = 2 so this is correct.
x = 9
√(6x - 38) = √(54 - 38) = √16 = 4 and 9 - 5 = 4 so 9 is also correct.
Let x and y be the two numbers.
We have x+y=-11 (because their sum is -11)
⇒ x= -11-y.
On the other hand, we also have x*y= -24 (because their product is -24)
⇒ (-11-y)*y= -24
⇒ -y^2 -11y= -24
⇒ y^2+ 11y -24= 0
⇒ ...
⇒ y= (-11-sqrt(217))/2 or y= (-11+sqrt(217))/2
x= (-11+sqrt(217))/2 or x= (-11-sqrt(217))/2 .
Conclusion: the two numbers are (-11+sqrt(217))/2 and (-11-sqrt(217))/2~
Answer:
D
Step-by-step explanation:
If you put it in the equation it would be m(4-5) which means it will be 4m-5m but it only asks for the 4m which is positive so increasing
