Answer:
9x + 5y + 11
Step-by-step explanation:
3x + 4y + y - 2x + 11 + 8x
Group like terms
(3x - 2x + 8x) + (4y + y) + 11
Combine like terms
9x + 5y + 11
Answer:
4
Step-by-step explanation:
Answer:
9x - 5
Step-by-step explanation:
<u>Simplify:</u>
- (4x − 6) + (5x + 1) = ⇒ opening parenthesis
- 4x - 6 + 5x +1 =
- (4x+ 5x) + (1 -6) = ⇒ grouping like terms
- 9x + (- 5) = ⇒ simplifying like terms
- 9x - 5 ⇒ answer
<u>Correct choice:</u> B. 9x -5
Answer:
4x + 3y = -3.
Step-by-step explanation:
First substitute into the point-slope form:
y - y1 = m(x - x1):
y - 3 = (-4/3)(x - -3)
y - 3 = (-4/3)(x + 3)
y - 3 = -4/3 x - 4
y = -4/3 x - 4 + 3
y = -4/3x - 1 Multiply through be 3:
3y = -4x - 3
4x + 3y = -3 (answer).
