9-5=4. 4 is half the number so 4x2=8. Your number is 8.
Answer:
1. 3x² - 75y² = 3(x+5y)(x-5y)
2. 4x³y⁸ + 6x⁴y² + 10x⁵ y¹⁰ = 2x³y²(2y⁶+3x+5x²y⁸)
3. x⁸ - 1 = (x⁴+1) (x²+1) (x+1) (x-1)
4. 64a³ m² - 216 m⁵ = 8m²(2a-3m) (4a²+ 6am+9m²)
5. 2x³+ 54y³ = 2 (x+3y) (x²-3xy+9y²)
I hope I helped you^_^
Answer:
(0, - 3 ) and (- 1, - 5 )
Step-by-step explanation:
Given the 2 equations
y = 4x² + 6x - 3 → (1)
y = 2x - 3 → (2)
Substitute y = 4x² + 6x - 3 into (2)
4x² + 6x - 3 = 2x - 3 ( subtract 2x - 3 from both sides )
4x² + 4x = 0 ← factor out 4x from each term
4x(x + 1) = 0
Equate each factor to zero and solve for x
4x = 0 ⇒ x = 0
x + 1 = 0 ⇒ x = - 1
Substitute these values into (2) for corresponding values of y
x = 0 : y = 2(0) - 3 = 0 - 3 = - 3 ⇒ (0, - 3 )
x = - 1 : y = 2(- 1) - 3 = - 2 - 3 = - 5 ⇒ (- 1, - 5 )
<span>First, to calculate one tenth of a number, you have to multiply it by .1 or move it one place/spot to the right in the number. The next step would be to identify two number next to each other that are identical. In the number 233,649, the 3 in the 10,000 place and the 3 in the 1,000 place would meet this requirement. As a result, if you were to multiply 30,000 (3 in 10,000 place) by .1 you would get 3,000 (3 in 1,000 place). The answer would be the 10,000 and 1,000 place contain digits that on one tenth the value of each other.</span>
