The answer is b because the ratio is blondes to brunettes.
Answer:
60
Step-by-step explanation:
Since all of the sides of this triangle are shown to be congruent, this must be an equilateral triangle. In an equilateral triangle, all of the angles are equal to 60 degrees. Therefore, x is 60. Hope this helps!
I think you just combine the like terms. Then you will get the equation in simplest form.
3) 492p
5) 133n-1
7) 495m+2
Step-by-step explanation:
1- 3x-3= 6 (x-10) organise the terms
2- 3x-3= 6x- 60 calculate (always brackets first)
2- 3x-6x= 3-60 Put the like terms on the correct side. Always put terms with x on the left.
3- -3x= -57 Calculate sums
4- x= -57÷-3=19 Divide
5- x= 19
The question is defective, or at least is trying to lead you down the primrose path.
The function is linear, so the rate of change is the same no matter what interval
(section) of it you're looking at.
The "rate of change" is just the slope of the function in the section. That's
(change in f(x) ) / (change in 'x') between the ends of the section.
<u>In Section A:</u>
Length of the section = (1 - 0) = 1
f(1) = 5
f(0) = 0
change in the value of the function = (5 - 0) = 5
Rate of change =
(change in the value of the function) / (size of the section) = 5/1 =<em> 5</em>
<u>In Section B:</u>
Length of the section = (3 - 2) = 1
f(3) = 15
f(2) = 10
change in the value of the function = (15 - 10) = 5
Rate of change =
(change in the value of the function) / (size of the section) = 5/1 = <em> 5
</em><u>Part A:</u>
The average rate of change of each section is 5.
<u>Part B:</u>
<span><span>The average rate of change of Section B is equal to
t</span>he average rate of change of Section A.
<u>Explanation:</u>
The average rates of change in every section are equal
because the function is linear, its graph is a straight line,
and the rate of change is just the slope of the graph.
