add up the purchases
2(9.95) + 14.95
19.90 +14.95
34.85
now find the sales tax
34.85 * .06 =2.091 = 2.09 (round to 2 decimal places with money)
add the purchases and the sales tax to get the total amount
34.85 + 2.09
$36.94
Answer:
y = - 2x² - 2x + 40
Step-by-step explanation:
Standard form of a quadratic is y = ax² + bx + c : a ≠ 0
Given
y = - 2(x + 5)(x - 4) ← expand factors using FOIL
= - 2(x² - 4x + 5x - 20)
= - 2(x² + x - 20) ← distribute parenthesis by - 2
= - 2x² - 2x + 40 ← in standard form
Answer:
C

Hope I helped. Please mark brainliest. Have a good day!
(1,11/4)(2,25/4)
slope = (25/4 - 11/4) / (2 - 1) = (14/4) / 1 = 14/4 = 7/2
y = mx + b
slope(m) = 7/2
(1,11/4)...x = 1 and y = 11/4
now we sub and find b, the y int
11/4 = 7/2(1) + b
11/4 = 7/2 + b
11/4 - 7/2 = b
11/4 - 14/4 = b
-3/4 = b
so ur equation is : y = 7/2x - 3/4
I think that it’s A, Perpendicular (correct me if I’m wrong)
