If you want to keep it technical, the normal “/unit rate” for running is minutes per mile. You can use dimensional analysis like I did below to find the answer. You should get 11.45 min/mile or about 11 min 25 sec per mile
8 + 12 + 20
20 - 9 = 11
11 - 2 = 9
Hope this helps! :)
Answer:
y - 13 = (5/2)(x - 4)
Step-by-step explanation:
Here we know the slope and one point on the line. Use the point-slope formula:
y - k = m(x - h).
Substituting 13 for k, 4 for x and 2.5 for m, we get:
y - 13 = (5/2)(x - 4)\
y + 7 = (x + 4)
the equation of a line in ' point- slope form ' is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
here m = and (a , b ) =( - 4, - 7)
y + 7 = (x + 4) → equation in point- slope form
Answer:
ab = -15
b + 6 = 3
a^c = 1/25
Step-by-step explanation:
ab means a*b. By looking at the values given, a*b = 5*-3, which equals -15.
b + 6 means the value obtained when you add 6 to b. By looking at the values given, b + 6 = -3 + 6, which equals 3.
a^c means a to the power of c. By looking at the values given, a^c = 5^-2, which equals 1/25.
Here's how to solve 5^-2.
1. Apply the exponent rule: a^-b = 1/a^b
1/5^2
2. Simplify.
1/25
