Answer:
a = -2/3
Step-by-step explanation:
Solve for a over the real numbers:
(3 a + 2) (4 a^2 - 2 a + 9) = 0
Split into two equations:
3 a + 2 = 0 or 4 a^2 - 2 a + 9 = 0
Subtract 2 from both sides:
3 a = -2 or 4 a^2 - 2 a + 9 = 0
Divide both sides by 3:
a = -2/3 or 4 a^2 - 2 a + 9 = 0
Divide both sides by 4:
a = -2/3 or a^2 - a/2 + 9/4 = 0
Subtract 9/4 from both sides:
a = -2/3 or a^2 - a/2 = -9/4
Add 1/16 to both sides:
a = -2/3 or a^2 - a/2 + 1/16 = -35/16
Write the left hand side as a square:
a = -2/3 or (a - 1/4)^2 = -35/16
(a - 1/4)^2 = -35/16 has no solution since for all a on the real line, (a - 1/4)^2 >=0 and -35/16<0:
Answer: a = -2/3
Answer:
Step-by-step explanation:
<h3>Given </h3>
Equations
<h3>To find </h3>
<h3>Solution</h3>
<u>Subtract the second equation from the first one side-by-side:</u>
- 5x + 2y - (x+ y) = 7 - 5
- 5x - x + 2y - y = 2
- 4x + y = 2
The answer is 2
Let the first number be = x
Then other number according to question is
4 less than 5 times the number i.e. 5x-4
Also ,sum of numbers is 32
x+5x-4=32
6x-4=32
Add 4 to both sides
6x-4+4=32+4
6x=36
Divide both sides by 6
x=36/6
x=6
First number =x =6
Other number =5(6)-4 = 30-4 =26
