Hey there!
First, multiply the second equation by -2 as the problem states. When you multiply the second equation by -2, you get:
-2x+4y=2
Now, add this equation to the first equation in which you simply combine like terms:
2x+y=3
+
-2x+4y=2
=
5y= 5
In conclusion, the correct answer would be the first choice.
Answer:
The length of line segment FG is equal to the length of F'G'
The perimeter of pentagon CDEFG is equal to the perimeter of pentagon C'D'E'F'G.
Step-by-step explanation:
Given
CDEFG and C'D'E'F'G
Translation: 7 units up and 5 units left
Solving (a): Segment FG and F'G'
When a shape is translated, the resulting image will have the same lengths as the original image (i.e, translation does not change measurements)
Hence:
Solving (b): Perimeter CDEFG and C'D'EF'G'
In (a), we established that lengths do not change during translation;
Hence:
The perimeter of the CDEFG and C'D'EF'G' will remain the same
Answer:
g(x) = 5x + 2.
r(x) = x
b(x) = 1/2 x³
k(x) = - 3 x + 1
Step-by-step explanation:
The function notation ⇒ it is the form to write the function, It is meant to be a precise way of giving information about the function, like f(x) , v(x) and so on.
Given the following:
g(x) = 5x + 2.
y = 1 x
h = x²
r(x) = x
f/x = x⁵ - 3
b(x) = 1/2 x³
p/x = -7x
k(x) = - 3 x + 1
y = mx + b
fx = -x³ + 4
So, in the given options the following are in function notations:
g(x) = 5x + 2.
r(x) = x
b(x) = 1/2 x³
k(x) = - 3 x + 1
