Answer:
A. 3.2% faster
B. 3.3% slower
C. 103.3%
Step-by-step explanation:
In order to find this out, we need to take the differences and divide them by the comparative time. So, in the first one, we take the difference (.32) and divide it by Hines time.
.32/9.63 = 3.2%
In the second, we take the difference and divide by Bolt's time.
.32/9.95 = 3.3%
And finally, in the last one, we take Hines' time and divide by Bolt's.
9.95/9.63 = 103.3%
Answer: B or D
Step-by-step explanation:
Answer:
m= 117
Step-by-step explanation:
Answer:
D. y = 5x - 11.
Step-by-step explanation:
One equation of a straight line is y = mx + c where m = slope and c = the y-intercept..
Lines which are parallel have the same slope.
So the equation will be y = 5x + c so we have to find c.
As we are given a point on the line we now use the point slope form:
y - y1 = m(x - x1) where (x1, y1) is a point on the line:
The point is (3, 4) so we have:
y - 4 = 5(x - 3)
y - 4 = 5x - 15
y = 5x - 15 + 4
y = 5x - 11.
