Step-by-step explanation:
Next, let's solve 3x+2y = 10 for the variable y. Move the 3x to the right hand side by subtracting 3x from both sides, like this: 3x - 3x = 0. The answer is 2y. The answer is 10-3x.
25.7 is 18.23% of 141.
Step-by-step explanation:
Let,
The percent be x.
Therefore,
x% of 141 = 25.7
Changing percent into 100 and multiplying x with 141.
1.41x = 25.7
Dividing both sides by 1.41
25.7 is 18.23% of 141.

E. 5x^2 - 10= 0; 5(x^2 - 2)= 0; x^2= 2; x = √2
f. x^2 - x=0; x(x -1)= 0; x = 0, x= 1
g. 4x^2 + 4x= 0 ; 4x( x + 1) = 0; x = 0, x = -1
h. -x^2 + x = 0; -x(x - 1)= 0; x = 0, x = 1
Answer:
Step-by-step explanation:
9x⁴ – 2x² – 7 = 0
Let's say that u = x²:
9u² – 2u – 7 = 0
Factor:
(u – 1) (9u + 7) = 0
u = 1, -7/9
Since u = x²:
x² = 1, -7/9
x = ±1, ±i √(7/9)
