Answer:
y = 3/2x - 4
Step-by-step explanation:
y = mx + b
*plugging in slope*
y = 3/2x + b
*finding b (aka y-intercept, starting value, when x=0) by plugging in x and y values from point (2, -1) )*
-1 = 3/2 * 2 + b
-1 = 3 + b
b = -4
so: y = 3/2x - 4
Discount %= 10%
Discount= x × 10%= x/10
Price after discount =x-(x/10)= 9x/10
But, given price after discount = rs 450
9x/10=450
9x=4500
x=4500/9= rs 500
ANSWER: X=2
4|2x-2|+10 = 34
4(2x+2)+10 = 34
8x+8+10 = 34
8x+18 = 34
-18 -18
8x = 16
➖ ➖
8 8
X = 2
Steps
1. -2 becomes +2 because of absolute value
2. Distribute the 4
3. Combine like terms
4. Subtract 18 from both sides
5. Divide both sides by 8 to get x alone
