Answer:
x = 2 and y = 5
Step-by-step explanation:
Given the simultaneous linear equations
y = 2x + 1 and x + y = 7
We are to find the value of x and y;
Substitute 1 into 2
From 2;
x+y = 7
x+2x+1 = 7
3x+1 = 7
3x = 7-1
3x = 6
x = 6/3
x = 2
Recall that y = 2x+1
y = 2(2) + 1
y = 4+1
y = 5
Hence the solution from the graph will be the point where the line cuts the x axis and this will be at x = 2 and y = 5
Answer:
8 3/25 because 8.12 is 8 12/100 and when you simplify 12/100 you get 3/25
Answer:
11. parallelogram, rectangle
12. parallelogram, rhombus
13. parallelogram, square
4pi/2pi = x/360
use a proportion
2 radians equals 360 degrees
x = 720 degrees
