Answer:
x = 4
Explanation:
For the right hand side:
log base 9 of 8 + log base 9 of (x-2) = log base 9 (8*(x-2))
= log base 9 of (8x-16)
For the left hand side:
2*log base 9 of x = log base 9 of x^2
Now, equating the two sides and solving for x:
log base 9 of (8x-16) = log base 9 of x^2
This means that:
x^2 = 8x - 16
x^2 - 8x + 16 = 0
(x-4)^2 = 0
Therefore:
x = 4

Step-by-step explanation:
Answer:
Ralphie's dad can eat 8 fruit bars without going over his calorie allotment.
Step-by-step explanation:
Given,
Per day calorie intake limit = less than 2126 calories
Calories are already taken = 1586 calories
Calories in each fruit bar = 66 calories
Let,
x be the number of fruit bars that Ralphie's dad can consume.
Calories in each fruit bar*Number of fruit bars + calories already taken < per day limit
Dividing both sides by 66
Words to the wise: Please express exponentials as x^2, not x2.
x2 + y2 = 81 should be <span>x^2 + y^2 = 81 = 9^2
Comparing this to x^2 + y^2 = r^2, we see that r= radius=9. y-intercepts are where x=0, so purposely set x=0 and solve for y:
0^2 + y^2 = 9^2. Then y = 9 or y = -9.
The graph intersects the y-axis at (0,9) and (0, -9).</span>
