The 2 ratios are almost equivalent, but not quite. In order to tell if they are equivalent, there are a number of ways but the 2 most common are 1, finding the decimal equivalent of the fraction, and 2, finding the scale factor.
1: Take 16, divide by 14. You should get something around 1.142. Take 64, divide by 60. You should get something around 1.066666.... Not equivalent.
2: Find the scale factor between the 2. To find scale factor, divide the larger numerator and larger denominator by the smaller numerator and smaller numerator. 64/16, 60/14. Not equal.
Answer:
B. -1
Step-by-step explanation:
If we have a parabola whose equation is:
The line of symmetry is calculated as:
Now, we have the equation 
and the line of symmetry is 
Where:
So, we can replace 
by -4 and 
by -2 and solve for 
using the following equation as:
It means that the equation of the parabola is equal to:
Since the exponent is on the outside of the paranthesis, you'd have to multiply it by everything on the inside: a^m x b^m
Answer:x<-7
Step-by-step explanation:
3x -15x - 30 > 54
-12x-30>54
-12x<54+30
I moved 30 from left side to right which becomes positive and > becomes <
-12x<84
-12x/-12<84/-12 I used my calculator to do this
x<-7
