The sum of the roots = -7/6
The product of the roots is -2/18
Therefore the quadratic equation is
18x^2 + 21x - 2
Answer:
There will be $7,900.
Step-by-step explanation:
Seeing as it will double every EIGHT years, and 5 is less than eight, the amount will stay the same.
Answer: x = -5
Step-by-step explanation:
First convert 3/4 to decimal= 0.75
0.75 (8x - 4) = 7x + 2
6x - 3 = 7x + 2
Transpose 7x from right hand side to the left hand side
6x - 7x = 2 + 3
-x = 5
x = -5
I hope this helps.
Hey there! :)
Answer:
x = 65°
Step-by-step explanation:
Find the measure of the other two angles using the Supplementary Angles theorem:
180 - 105 = 75°
180 - 140 = 40°
The sum of all of the angles in a triangle is equal to 180°, therefore:
180 = 75 + 40 + x
180 = 115 + x
65 = x
x = 65°
