Answer:
1/5
Step-by-step explanation:
(5^7*5^5)/5^13 (when multiplying numbers with the same base, add the exponents)
= (5^12)/5^13 (when dividing exponents with the same base, subtract the exponents)
= 1/5^1 (anything to the first power is itself)
= 1/5
Answer:
C. 10
Step-by-step explanation:
Slope / Gradient: (y - y¹) / (x - x¹)
Using points (-20, 0) and (-10, 1)
= [-20 - (-10)] / [0 - 1]
= -10 / -1
= 10
Answer:
y = 2
Step-by-step explanation:
use slope formula:
(4 - y) / (3 - 10) = -2/7
4-y / -7 = -2 /7
cross-multiply:
7(4 - y) = (-7)(-2)
28 - 7y = 14
-7y = -14
y = 2
