Multiply the number outside the parenthesis by each term inside the parenthesis:
2(v+5) = 2v + 10
I don't understand what one
Answer:
B
Step-by-step explanation:
B'(7, -4)
Let the pre-image coordinates be (x,y)
Consider x-coordinate,
x + 4 = 7
x = 3
Consider y-coordinates,
y + 5 = -4
y = -9
pre-image coordinates is (3, -9)
Answer:
y= 4/9x+136/9
Step-by-step explanation:
Write in slope-intercept form, y = mx = b
1) Those are polar coordinates
2) The expression inside cosine is the angle of the vector to be drawn
3) r is the length of the vector to be drawn.
For example:
- if you take angle =0 and r results to be =2, it means that you have to put a point over the x-axis at a distance of two units from the origin.
4) You have to look for notable values, like points on the axis and notable angles (0, 45°, 90°, 180 °,...)
5) Use derivation to find maximum and minimum values.
6) The graph of this function looks like the infinite symbol: ∞
7) Some notable points are: (0,0) ; (0,2) ; (0, - 2)
See attached the complete graph as a reference.
