Answer:
6x^2- 27x
Step-by-step explanation:
distribute 5 through parenthesis
change - sign from in front of parenthesis
combine like terms
Q1: y = -3/2x +1
Q2: The graph changes vertically from -1 to 3 (4 units) at the same time it changes horizontally from -4 to 1/2 (4.5 units). The rate of change is 4/4.5 = 8/9 ≈ 0.8889. The closest answer selection is 9/10.
Q3: x=-2
Q4: The graph changes vertically by -4 at the same time it changes horizontally by +1. The slope is 4/-1 = -4. The y-intercept is +1, so the equation is
.. y = -4x +1
Q5: After the same pattern as above,
.. y = 5/2*x +5
Answer:
x = 72 degrees
Step-by-step explanation:
Use the definition of a tangent function:
tan x = opposite/adjacent
= 154/50
= 3.08
----> x = arctan 3.08 = 72 degrees
