1-2x=-3x+2
-1=-x
1=x
Answer:
6x² + 5x - 6
Step-by-step explanation:
Given
(2x + 3)(3x - 2)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(3x - 2) + 3(3x - 2) ← distribute both parenthesis
= 6x² - 4x + 9x - 6 ← collect like terms
= 6x² + 5x - 6
Answer:
4) slope= 0
5) 
Step-by-step explanation:
4) Slope
= 0
The slope is zero as the line is a horizontal line (since both points have the same y-coordinate of 10).
5) Slope
Since you have taken (x₁, y₁) to be (9, 4), the value of x₁ should be 9 instead of 2.
Answer:
7
Step-by-step explanation:
25x^2 - 64y^2
The first thing you can do is look for a subtraction sign. The word difference implies subtraction, so you can rule out any expressions that add terms. Secondly, you can look for squares. 17x^2 - 23y^2 is a subtraction expression, but 17 and 23 are not squares. However, 25x^2 - 64x^2 is a subtraction expression and its terms are squares. 25 = 5x5, 64 = 8x8. Hope this helps!
