Answer:
see the procedure
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
we have
The remaining length (L) of 120-inch rope after x inches have been cut off
we have
L ---> is the dependent variable (output variable)
x ---> the independent variable (input variable)
The linear equation is
The equation not represent a proportional relationship, because the line not passes through the origin
Answer:
x=1
Step-by-step explanation:
simplify and create a chart of denominators until you find the common one.
Answer:
2 and 2/3 for the first question
-1/8 for the second one
-1/5 for the third one
ive never done this type of question or maybe it was too long ago for me to remember but out of this answer choices i would guess that its the last one
this is 3
Step-by-step explanation:
you add the numerators which is the top number in order to get 2 and 2/3rds
you subtract 5 from 4 to get -1/8
same situation as the last one, subtract 15 from 11 to make it a negative 4/20 and then simplify that by dividing it by four to get 1/5th
this one i dont understand or remember how to do very well but if i had to guess its the last answer choice
this one you add 3/4 plus 1/4 in order to get 4/4 or rather 1, so basically its asking what 1+1+1 is which is 3
Answer:
x=5
Step-by-step explanation:
4x−6−x=x+9−x
3x−6=9
Step 2: Add 6 to both sides.
3x−6+6=9+6
3x=15
Step 3: Divide both sides by 3.
3x
3
=
15
3
x=5
Well, you know the first set can't be the answer, since it makes it such that x is more than 1:
<span>{x | x e R, x > 1}
and our set clearly includes 1. And since each of the numbers in the set are whole numbers, set two can not be right, because it does not specify that numbers must be whole. it only specifies that numbers must be real and more than 1. Thus the third set is the answer.
