Answer: Choice D
which is the log base 6 of x
====================================================
Explanation:
Since you're given a list of choices, you can plug in each x coordinate of the points shown and see what the y values are.
If you plugged x = 6 into choice A, you would end up with y = -1 but we want y = 1 instead. So choice A can be crossed off the list.
If you plugged in x = 6 into choice B, then you would get y = -2.6 approximately. So this answer won't work either.
Try x = 6 into choice C, and you'll get a division by zero error. So that can be crossed off too.
The only thing left is choice D. This function works because x = 0.5 leads to y = -0.4 approximately. Also, x = 1 and y = 0 pair up together. Similarly, the input x = 6 produces the output y = 1.
note: you may have to use the change of base formula to compute the log values. The change of base formula is log(b,x) = log(x)/log(b)
Answer: 15 miles
Step-by-step explanation:
The equation is 5.25+1.25x=24 where x is each additional mile so to solve for x it would be 1.25x=18.75 and divide both sides to solve for x
A ) equation would be X = Z / Y
B ) if X = 9 ------------> Y = 1/7
X = 21 ----------> Y = ?
21*1/7 = 21/7 , 21/7÷9 = 21*9/7 = 27
so Y equal 27
-6x + 100 = -10x + 160
+ 10x + 10x
4x + 100 = 160
- 100 - 100
4x = 60
4 4
x = 15
