Answer:
1
Step-by-step explanation:
the degree of the polynomial is 1
this is because we just have to look at the degree of the biggest monomial in the polynomial
the largest monomial is 3x, and the degree of that is 1
Answer:
x = sqrt(y/2 + 9/16) - 7/4 or x = -sqrt(y/2 + 9/16) - 7/4
Step-by-step explanation:
Solve for x:
y = 2 x^2 + 7 x + 5
y = 2 x^2 + 7 x + 5 is equivalent to 2 x^2 + 7 x + 5 = y:
2 x^2 + 7 x + 5 = y
Divide both sides by 2:
x^2 + (7 x)/2 + 5/2 = y/2
Subtract 5/2 from both sides:
x^2 + (7 x)/2 = y/2 - 5/2
Add 49/16 to both sides:
x^2 + (7 x)/2 + 49/16 = y/2 + 9/16
Write the left hand side as a square:
(x + 7/4)^2 = y/2 + 9/16
Take the square root of both sides:
x + 7/4 = sqrt(y/2 + 9/16) or x + 7/4 = -sqrt(y/2 + 9/16)
Subtract 7/4 from both sides:
x = sqrt(y/2 + 9/16) - 7/4 or x + 7/4 = -sqrt(y/2 + 9/16)
Subtract 7/4 from both sides:
Answer: x = sqrt(y/2 + 9/16) - 7/4 or x = -sqrt(y/2 + 9/16) - 7/4
1) 16y - 24x = 8 (2y - 3x)
2) 3x - 6x²y + 12x²= 3x(1 - 2x²y + 4x)
3)2x² - 10x = 2x ( x -5)
4) 15x² - 20x³ = 5x²(3 -4x)
If you explain what they mean by DOTS i might be able to help you from 5-8
hope it helps for 1-4 tho
