Answer:
$20.60
Step-by-step explanation:
Price before discount = $21
Discount rate = 10% or 0.1
Discount in dollars = 0.1* 21 = $2.1
Price after discount = $21 -$2.1 = <em>$18.90</em>
If sales tax is 9% or 0.09
amount of tax will be = 0.09 * 18.90 = <em>$1.701</em>
Total price of the phone including taxes = Price before tax + tax amount;
Total price = 18.90 +1.701
= 20.601
Therefore total price will be $20.60
Answer: 2/3
Step-by-step explanation:
Slope is rise over run. From red point to first blue point you go up 2 and over 3.
Answer:
D F/a =m Mrs Kaulter
Step-by-step explanation:
F = ma
Divide each side by a
F/a = ma/a
F/a =m
Answer:
y = - 3x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + y + 2 = 0 ( subtract 3x + 2 from both sides )
y = - 3x - 2 ← in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, thus
y = - 3x + c ← is the partial equation
To find c substitute (3, - 4) into the partial equation
- 4 = - 9 + c ⇒ c = - 4 + 9 = 5
y = - 3x + 5 ← equation of line in form y = mx + c
