Answer:
I know an app its called math-way its really good for math
Step-by-step explanation:
Answer: Horizontal is y=8 and vertical is x=-4
Step-by-step explanation:
Answer is c. -2 (cannot be in the solution set of w/-2)
because.
a) -1/-2 = 1/2 and 1/2 < 1
b) 1/-2 = -1/2 and -1/2 <1
d) 2/-2 = -1 and -1 <1
but
c) -2/-2 = 1 and 1 = 1
Answer:
The upper bound for the perimeter of the rectangle = 427.76 cm
Step-by-step explanation:
To obtain the upper bound for the perimeter, we need to first obtain the upper bound for the Length and Breadth of the rectangle.
Since, these dimensions were rounded to the nearest 1 decimal place, we can write down their ranges
Length = 127.3 cm
Width = 86.5 cm
Length can range from 127.25 cm to 127.34 cm
Breadth can range from 86.45 cm to 86.54 cm
The upper bound for the Length and Breadth of the rectangle are this 127.34 cm and 86.54 cm respectively.
Perimeter = 2 (L + B)
Upper bound of the perimeter
= 2 × (127.34 + 86.54)
= 2 × 213.88
= 427.76 cm
Hope this Helps!!!
The absolute value sign makes it so that k+7 could be either -3 or +3 and the result would still be 3. This means there are two possible answers for k. The one that makes k+7=-3 and the one that makes k+7=+3. Just solve these two equations:
k+7=-3
k=-3-7
k=-10
k+7=3
k=3-7
k=-4
So the possible answers are -4 and -10. B is the correct choice.
