the line in slope intersect form has two types of information:
- how steep it is
- the height of the line
Answer:
$3.00 is the constant
Step-by-step explanation:
let x be the mile driven then
total charge=$3.00+[x($0.30)]
Answer:
The value of x = -0.46
Step-by-step explanation:
∵
÷ 
∴ 
* Subtract the power of the same bases
∴ 
* Let 
∴ 
∴ 4y² - 1 = -3y
∴ 4y² + 3y - 1 = 0 ⇒ factorize
∴ (4y - 1)(y + 1) = 0
∴ y + 1 = 0 ⇒ y = -1
∴ 4y - 1 = 0 ⇒ 4y = 1 ⇒ y = 1/4
∵ 
∴ y = -1 refused (
never gives -ve value)
∴
⇒ insert <em>ln</em> in both sides
∵
⇒ <em>ln</em>(e) = 1
∴ 3xln(e) = ln(1/4)
∴ 3x = ln(1/4)
∴ x = [ln(1/4)] ÷ 3 = -0.46
