2y(4z)=8yz
each major road of city y you have 4 different routes so if there're 2 routes of city y then double the number of routes and you get 8 different roads to travel in from x to z through y
The answer will be 10/3 also I'll recommend downloading photo math it really helps!! It's free.
Answer:
Step-by-step explanation:
Tn = ar^(n-1)
a = 4, r = 8/4 = 2 for n = 15
T15 = 4 × 2^(15-1)
= 4 × 2^14
= 4 × 16384
= 65536
Answer:
x = ±1
Step-by-step explanation:
=> 7x² = 13-6
=> 7x² = 7
<em>Dividing both sides by 7</em>
=> x² = 1
<em>Taking sqrt on both sides</em>
=> x = ±1
Answer:
f(0) = -3
x increases by 1 f(x) increase by 2
f(x) = 2x -3
Step-by-step explanation:
Looking at the graph
f(0) means when x =0 the value of y = ?
when x = 0 y = -3
f(1) means when x = 1 y = ?
When x = 1 y = -1
y increased from -3 to -1 so it increased by 2
f(x) = ax+b where a is the increase and b is the value at x =0
f(x) = 2x -3
