Final solution:
From 9 P.M. to 5 A.M. the temperature dropped 20°, making the rate over 8 hours, -2.5° Per Hour. By 5 A.M., the temperature is -5° since we had to do 15 - 20. From 5 AM to 5 P.M. is 12 hours so -2.5 x 12 = -30 making 30 how much the temperature dropped between 5 A.M. to 5 P.M. Finally, our last equation is -5 - 30 making -35 our answer.
31.7 + 42.8 + 26.4 + x/4 = 39.1
Add up all the plain numbers on the left side:
100.9 + x/4 = 39.1
Subtract 100.9 from each side:
x/4 = 39.1
Multiply each side by 4:
<em>x = 156.4</em>
Answer:
The equation would be x + 2y = -8
Step-by-step explanation:
To find the standard form of this line, start by using point-slope form with the given information. Then solve for the constant.
y - y1 = m(x - x1)
y + 3 = -1/2(x + 2)
y + 3 = -1/2x - 1
1/2x + y + 3 = -1
1/2x + y = -4
x + 2y = -8
1. The slope is 12 and the y-int. Is -4 2. The slope is 1 and the y int. Is 3 3. The slope is 3 and the y-int. Is -6
