Answer:
2nd Option
3rd Option
Step-by-step explanation:
Linear equations are equations with a variable degree of 1.
Choice 1 is a function and a linear equation
Choice 4 is a linear equation but <em>not </em>a function
Quadratic equations are equations with variable degree of 2
(So choice 2 isn't a linear equation)
Cubic equations are equations with variable degree of 3
(So choice 3 isn't a linear equation)
Answer:
x = 14
Step-by-step explanation:
-2(x-5)-4=-22
Distribute
-2x +10 -4 = -22
Combine like terms
-2x+6 =-22
Subtract 6 from each side
-2x+6-6 = -22-6
-2x = -28
Divide each side by -2
-2x/-2 = -28/-2
x = 14
have you tried referring to the back of your textbook lots of them have eoc type questions in the back and I'm sure there are online pfds of algebraic eco practices
Answer:
∠ ABD = 49°, ∠ CBD = 28°
Step-by-step explanation:
∠ ABD + ∠ CBD = ∠ ABC , substitute values
3x + 22 + 5x - 17 = 77 , that is
8x + 5 = 77 ( subtract 5 from both sides )
8x = 72 ( divide both sides by 8 )
x = 9
Thus
∠ ABD = 3x + 22 = 3(9) + 22 = 27 + 22 = 49°
∠ CBD = 5x - 17 = 5(9) - 17 = 45 - 17 = 28°
