Answer:
y = -3.5x - 12
Step-by-step explanation:
Find the slope with rise over run: (y2 - y1) / (x2 - x1)
Plug in the points:
(9 + 5) / (-6 + 2)
14/-4
= -3.5
Then, plug this and a point into the equation y = mx + b to find b:
y = mx + b
9 = -3.5(-6) + b
9 = 21 + b
-12 = b
Then, plug this and the slope into the equation again:
y = mx + b
y = -3.5x - 12 will be the equation
Answer:
5 rides.
Step-by-step explanation:
$28 - $6.50 = $21.50
$21.50 - $4 = $17.5
$17.5 ÷ $3 = 5.83
2r² + 3s³ - r² + 4t² - r² = 3s³ + 4t²
<span>if s = -3 and t = 5
</span>3s³ + 4t² = 3 * (-3)³ + 4 * 5² = 3 * (-27) + 4 * 25 = -81 + 100 = 19
Answer: 19
Answer:
Discounted amount = $10
Sales price = $40
Step-by-step explanation:
Given:
Phone cost = $50
Discount rate = 20%
Find:
Discounted amount and sales price
Computation:
Discounted amount = Phone cost x Discount rate
Discounted amount = 50 x 20%
Discounted amount = $10
Sales price = Phone cost - Discounted amount
Sales price = $50 - $10
Sales price = $40
