Answer:
1. y = 2x-4
2 y = -1/2x+3
Step-by-step explanation:
Slope intercept form of the equation is y= mx+b
where m is the slope and b is the y intercept
1. y- 2x = -4
We need to solve for y
Add 2x to each side
y -2x+2x = 2x-4
y = 2x-4
2 y-3 = -1/2 x
We need to add 3 to each side
y-3+3 = -1/2x +3
y = -1/2x+3
Answer:
19/9
Step-by-step explanation:
We are given repeating decimal number 2.1¯.
We know 2.1¯ = 2.1111..... repeating 1's.
Let us assume x is a fraction equals given repating decimal number.
And set it as a first eqaution.
x = 2.1111..... ------------- (equation 1).
Multiplying equation both side by 10 ( because only one digit is repeating after decimal, we multiply by 10).
On multiplying by 10 we get
10*x = 10*2.1111.....
10x = 21.1111...... ----------------- (equation 2)
Subtracting equation 1 from equation 2, we get
10x = 21.1111......
-x = -2.1111.....
_____________
9x = 19.
Now, dividing both sides by 9. we get
