Answer:
The expression is 4x² and coefficient is 4.
Step-by-step explanation:
All have the same variables, x², so you add up together :


Answer:
d = 14/5
Step-by-step explanation:
The point (-4,2) means that;
At x = -4, y = 2
Now general form of a linear equation is;
Ax + By + C = 0
We are given;
4y = 3x + 6
Rearranging to the form of a linear equation gives;
3x - 4y + 6 = 0
Thus, A = 3, B = -4 and C = 6
Thus, at point (-4,2), distance between them is;
d = (3(-4) - 4(2) + 6)/√(3² + (-4)²)
d = -14/5
We will take the absolute value.
Thus; d = 14/5
Combine like terms
assuming those 2s are exponents
-3x^2+2y^2+5xy-2y+5x^2-3y^2
move all x's together all y's together and all xy's together
-3x^2+5x^2+2y^2-3y^2+5xy
combne like terms
2x^2-y^2+5xy
3 terms
1 term is negative
A complement adds up to 90 degrees, so we just need to halve that, to get 45 degrees.
