Step-by-step explanation: calculate the prime factors of 7 and 21, than find the greatest common factor
Answer:
x = 40
Step-by-step explanation:
5= 1/5x -3
Add 3 to each side
5+3= 1/5x -3+3
8 = 1/5x
Multiply by 5 to isolate x
5*8 = 1/5x *5
40 =x
Answer: The required transformation rule is given by
(x, y) -----> (-x, y).
Step-by-step explanation: We are given to write a rule that describes a transformation across the y-axis.
We know that
if a point is reflected across the y-axis, then the sign before the x co-ordinate changes.
That is, if the point (x, y) is reflected (transformed) across the y-axis, then its new co-ordinates will be
(-x, y).
Thus, the required transformation rule is given by
(x, y) -----> (-x, y).
The solution to the system of equation is (3/2, -1/2)
<h3>System of equations</h3>
Given the following system of equations as shown;
(3x+y=4 .... * 4
2x-4y=5 ..... * 1
_______________
12x+4y=16
2x-4y=5
Add both equations
12x+2x = 16 + 5
14x = 21
x = 3/2
Substitute x = 3/2 into any of the equation to have;
2x-4y=5
2(3/2) - 4y = 5
3 - 4y = 5
-4y = 5 - 3
-4y = 2
y = -1/2
Hence the solution to the system of equation is (3/2, -1/2)
