Answer:
x = -2/7
Step-by-step explanation:
The excluded values of the given expression are all the values of x that will make the denominator (7x + 2) = 0. This is because you cannot divide by 0...at least in algebra.
1. 7x + 2 = 0
7x = -2
x = -2/7
Therefore, x = -2/7 is the excluded value.
Answer:
13
Step-by-step explanation:
All the lengths in triangle ADE are twice those in similar triangle ABC. So ...
x-1 = 2(6)
x = 13
Answer:
The type of food they are feeding the dog.
Step-by-step explanation:
The independent variable is the test variable of the experiment. Therefore, you can see that Pablo and Johanna both use different types of food to feed their dogs, to see which one grows faster. The growing faster is the dependent variable because how fast the dogs grow is what is being measured.
An hour is 60mins or 1 rotation
so
the hand moves 35/60 of the circumference of the clock
so
c=2pir
r=length of hand=7
c=2pi7
c=14pi
then, we have 35 out of 60 mins or 35/60=7/12
7/12 times 14pi=98pi/12=49pi/6≈25.66 inches
