<h3>Answer: C. outside temperature and heating bill</h3>

Explanation:

A negative trend is when one variable goes up and the other variable goes down (or vice versa).

As the temperature goes down, the heating bill is likely to go up. This is of course assuming the person(s) use the heat to stay warm rather than just solely rely on something like coats/blankets/etc.

As the temperature goes back up, there's little to no need for heating. So the heating bill will likely go down.

As the name implies, negative trend graphs have negative slopes for the regression lines.

Can someone please help me on solving: x+y=-4

timama [110]

Answer: x=-1 and y= -3

Step-by-step explanation:

Solve for x, x+y=-4

Minus y from both sides so it'll be X=-y-4

Now substitute -y-4 in x-y=2 and solve for y

-y - 4 -y=2

Add like terms, -2y - 4=2

Add 4 to both sides -2y=6

Divide both sides by -2 $\frac{-2y}{-2} = \frac{6}{-2}$

y= -3

Substitute -3 in x=-y - 4

x=-(-3) - 4

- × (-3)= 3

3 - 4= -1

x= -1

5. The recursive algorithm given below can be used to compute gcd(a, b) where a and b are non-negative integer, not both zero.

s2008m [1.1K]

Implementating the given algorithm in python 3, the greatest common divisors of (124 and 244) and (4424 and 2111) are 4 and 1 respectively.

The program implementation is given below and the output of the sample run is attached.

def gcd(a, b):

#initialize a function named gcd which takes in two parameters

if a>b:

#checks if a is greater than b

return gcd (b, a)

#if true interchange the Parameters and Recall the function

elif a == 0:

return b

elif a == 1:

return 1

elif((a%2 == 0)and(b%2==0)):

#even numbers leave no remainder when divided by 2, checks if a and b are even

return 2 * gcd(a/2, b/2)

elif((a%2 !=0) and (b%2==0)):

#checks if a is odd and B is even

return gcd(a, b/2)

else :

return gcd(a, b-a)

#since it's a recursive function, it recalls the function with new parameters until a certain condition is satisfied

print(gcd(124, 244))

print()

#leaves a space after the first output

print(gcd(4424, 2111))

Can someone check my work?. 1. Simplify the given expression.. (7 − 3i) • (2 − i) . 4 + i (MY ANSWER) . . 14 + 3i . . 11 − 13i .

Annette [7]

1. (7 − 3i) • (2 − i)
It is simplified as follows:
14 - 7i -6i - 3
11 - 13i

2. (−5 + 3i) • (1 − 2i)
It is simplified as follows:
-5 + 10i + 3i + 6
1 + 13i

3. (1 + 3i) + (2 − 5i)
It is simplified as follows:
1 + 3i + 2 − 5i
3 - 2i

4. (6 + 2i) − (8 − 3i)
It is simplified as follows:
6 + 2i − 8 + 3i
-2 + 5i
