To go from the original to number I you need to do a reflection across the y-axis. To go from I to II you need to do a 90 degree clockwise rotation about the origin.
Answer:
y = 8x + 8
Step-by-step explanation:
The y-intercept is already given so we have our b = 8 so y = mx + b becomes y = mx + 8. Now we need to figure out the slope so looking at the chart I need to figure out what number when multiplied by the x value and added to b equals the y value. The answer is 8 because when we multiply it by 1 and add it to 8 we are left with 16, which supports the chart. The equation in slope intercept form is now y = 8x + 8
By the Pythagorean Theorem, we are looking for
, or <u />

Loga x=n ⇔a^n=x
Therefore:
log₄ (x+20)=3
3⁴=x+20
64=x+20
x=64-20
x=44
Answer: x=44
