72/rate=time
72/9=8 years
So the answer is c
Answer:
x = 4
y = 1
Step-by-step explanation:
x = 3y + 1 (Multiply everything by -2)
2x + 4y = 12 (Transfer 4y to the right of the = sign)
2x = -4y + 12
-2x = -6y - 2
0 = -10y + 10
-10 = -10y
y = 1
x = 3y + 1
x = 3(1) + 1
x = 3 + 1
x = 4
Answer:
36°
Step-by-step explanation:
Unknown Angle = 180° - 88° - 56°
Unknown Angle = 36°
33 degrees C
Step-by-step explanation:
On the integer scale, the numeric values can be added thus
23 to -10
23 to 0 and 0 to -10
23-0 = 23
0 -(-10) = 10
23 + 10 = 33
Thus, 33 degree C is the difference between the two temperatures.
Well, looking at the graph, notice, its vertex is at 0,9, and it passes through the points -3,0 and 3,0, so hmm let's use 3,0, to get the equation of f(x)
