For easy calculation first transpose the equation into the y-intercept form then create your table and plot the graph.
If 2x - 6y = 12
then -6y = 12 - 2x
6y = 2x - 12
y = [2 (x - 6)] /6
⇒
y = (x - 6) / 3
The table and graph are attached below.
The value of f(2a) is 8a
<h3>What is a function?</h3>
A function can be defined as a rule or expression that shows the relationship between a dependent and independent variable.
From the information given, we have;
g(a) = 4a
Let's determine the value for f(2a)
a = 2a
Let's substitute the value of a as 2a in the function
g(a) = 4a
g(2a) = 4 ( 2a)
Multiply through
g(2a) = 8a
Thus, the value of f(2a) is 8a

Answer:
The answer is 53 or Square Root (sqrt) of 2809
Step-by-step explanation:
a^2+b^2=c^2
28^2+45^2=c^2
784+2025=c^2
c^2=sqrt 2809
c = 53
16x + 64

Answer:
Elliot will make 4 hats and 16 scarves
Step-by-step explanation:
Let x be the number of hats and y be the number of scarves Elliot will make.
Elliott wants to make a total of 20 items, then
x + y = 20
Each hat uses 0.2 kilograms of yarn, so x hats use 0.2x kilograms of yarn and each scarf uses 0.1 kilogram of yarn, then y scarves use 0.1y kilograms of yarn. Elliott wants to use twice as much yarn for scarves as for hats, then
0.1y = 2(0.2x)
Thus,
0.1y = 0.4x
y = 4x
Substitute it into the first equation:
x + 4x = 20
5x = 20
x = 4
y = 20 - 4
y = 16
Hence, Elliot will make 4 hats and 16 scarves
