Answer:
0.4069 ; 1.843
Step-by-step explanation:
Given:
Base of parallelogram, b = (2x - 1)
Height = (4x - 7)
Area = 1
Area of parallelogram = Base * height
Area of parallelogram = (2x - 1) * (4x - 7)
(2x - 1) * (4x - 7) = 1
8x² - 14x - 4x + 7 = 1
8x² - 18x + 7 - 1 = 0
8x² - 18x + 6 = 0
Divide through by 2
4x² - 9x + 3 = 0
Solving the quadratic equation :
Using the formula
-b ± √(b² - 4ac) / 2a
a = 4 ; b = - 9 ; c = 3
Plugging in the values :
-(-9) ± √((-9)² - 4(4)(3)) / 2(4)
9 ± √(81 - 48) / 8
9 ± √33 / 8
(9 ± 5.7445626) / 8
(9 - 5.7445626) / 8) = 0.4069
(9 + 5.7445626) / 8 = 1.843

Answer:
Hello! answer: 30 and 150
Step-by-step explanation:
supplementary angles add up to 180 degrees
2 × 15 = 30
10 × 15 = 150
150 + 30 = 180 degrees therefore C is the only answer that works in this scenario
and x = 15 just a little more info
1/2 bedroom .... 3/4 hours
2/2 bedroom ........x hours
x = (2/2x3/4)/1/2 = (3/4)/(1/2) = 6/4 hours = 1 1/2 hours = 1 hour 30 minutes
Answer:
y=-3/2x-4
Step-by-step explanation:
because the slope of a perpendicular line is opposite reciprocal
