The answer is 6 since the scale factor is 2 and 3x2 is 6
Answer:
The equation for the trend line would be y = -1/100x + 25
Step-by-step explanation:
In order to find the trend line, we first need to find the slope. To do so, we need to find two points on the line. The points we'll use are (0, 25) and (2500, 0). Next, we use the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (0 - 25)/(2500 - 5)
m = -25/2500
m = -1/100
Now that we have this we can use the slope and the intercept in slope intercept form to model the trend line.
y = mx + b
y = -1/100x + 25
Answer:
x 
4
Step-by-step explanation:
4x^2 - 64 0 ; move 64 over
4x^2 64 ; divide by 4
x^2 16 ; take square root of both sides
x 4
