14. 4.5 km/21 min = 7.5 km = x min
cross multiply
4.5x = 7.5(21)
4.5x = 157.5
x = 35 min
B
15. 9.60/12 = x/4
cross multiply
12x = 4(9.60)
12x = 38.40
x = 3.20

Answer:
Dollars and graph 1 is proportional 2 is not
Step-by-step explanation:
Answer:
An equation that represents the line is:
y = 3/4x - 9/2
Step-by-step explanation:
The slope-intercept form of the line equation
where
Given the attached graph of a line.
Taking two points from the line, such as
Determining the slope between (2, -3) and (0, 6)


refine

substituting m = 3/4 and the point (2, -3) in the slope-intercept form of the line equation
y = mx + b


subtract 3/2 from both sides


now substituting b = -9/2 and m = 3/4 in the slope-intercept form of the line equation
y = mx + b
y = 3/4x + (-9/2)
Therefore, an equation that represents the line is:
y = 3/4x - 9/2
Rewind the "mind movie" of what happened. She added $74 to her account and then had $192. Back it up by subtracting the $74 from $192.
192 - 74 = 118
Answer:
Step-by-step explanation:
find the difference between the two angles first:
155-65=90 degrees
d is the distance d:
d^2=a^2+b^2-2ab cos(90)
d^2=10^2+8^2-2(10)(8)cos(90)
d^2=164
d=√164=12.81
the bearing of R from P to the nearest degree:
180-155=35 degrees
