, b
, and c of the quadratic then applying the quadratic formula.
Answer:
∠J = 107°
∠K =107°
∠L = 73°
∠M = 73°
Step-by-step explanation:
Angle J + angle M = 180°
(10x - 33) + (4x+17) = 180
simplify:
14x -16 = 180
14x = 196
x = 14
∠J = 10(14) - 33 = 107°
∠M = 4(14) + 17 = 73°
Answer:
$39.68
Step-by-step explanation:
12.40÷2.4=4.96
4.96×8=39.68
Answer:
y=5/3 is the only real solution
Step-by-step explanation:
Solve for y over the real numbers:
11 y^2 - 19 y - 10 = -4 y^2
Add 4 y^2 to both sides:
15 y^2 - 19 y - 10 = 0
The left hand side factors into a product with two terms:
(3 y - 5) (5 y + 2) = 0
Split into two equations:
3 y - 5 = 0 or 5 y + 2 = 0
Add 5 to both sides:
3 y = 5 or 5 y + 2 = 0
Divide both sides by 3:
y = 5/3 or 5 y + 2 = 0
Subtract 2 from both sides:
y = 5/3 or 5 y = -2
Divide both sides by 5:
Answer: |
| y = 5/3 or y = -2/5
