Hey there! :D
So I want you to think of a function as an input and output, where f(x)= y and x=x.
(x,y)
(0.4, 0.2)
So when 0.4 is equal to x, y is equal to 0.2.
So, you can plug in the point you do know.
(1.6, y)
Divide x by 0.4.
1.6/0.4= 4
0.2*4= 0.8
f(x)= <em>.8 </em><em>
</em>
I don't know if you added another 0 to the decimal, but the function is set up so that f(x) is half of x. 1.6/2=.8 That is the answer.
I hope this helps!

A. 70°
Supplementary angles always = 180°
Where 180 - 110 = 70
110+ 70 = 180
It’s a hollow cylinder, since a rectangle rotated like that results in a cylinder. If that’s not a good explanation, then picture rotating it, and hopefully you’ll get it ♡
Answer:
Look for bolded sentences
Step-by-step explanation:
1. Let n be the first number. The second number would be n+5. Now let's write an equation...
n+n+5=17
2n+5=17
2n=12
n=6
n+5=11
The numbers are 6 and 11
2. Let n be the first number. The second number would be n+12...
n+n+12=60
2n+12=60
2n=48
n=24
n+12=36
The numbers are 24 and 36
3. Let n be the number of boys. The number of girls is n+36...
n+n+36=812
2n+36=812
2n=776
n=388
n+36=424
424 girls attend the school
4. Let the amount of money Stan has be n. Then Cory has 2n+24...
n+2n+24=132
3n+24=132
3n=108
n=36
2n+24=2(36)+24=72+24=96
Stan has $36 and Cory has $96

Step-by-step explanation:
The question is incomplete, as the coordinates of the three vertices.
I will answer your question using the following illustration.
Assume that the square is ABCD are the given coordinates are:
Required
Find D
Let the coordinates of D be:

Calculate the slope of each side.
AB, BC, CD and DA using:
AB:
--
--
So:
BC:
--
--
So:
CD:
--
--
So:
DA
--

AB and CD are parallel sides. So, they have the same slope
i.e.
Solve:
Make y the subject
---- (1)
BC and DA are parallel sides. So, they have the same slope
i.e.
Solve:
Make y the subject
---- (2)
So, we have:
and
Equate both:
Collect like terms
Solve for x
Substitute in
So, the missing coordinate is:
