the rate is usually the number in the parentheses in an exponential function, now the tell-tale piece is that, if the rate is less than 1, we have a Decay expression, and if the rate is more than 1, then is Growth.
well, let's see 0.365 is less than 1, so it's Decay.
Answer:
y=49x
Step-by-step explanation:
As you can see from the graph, the distance from home increases by 49 miles per hour driven.
Therefore the distance driven for any given time in hours is 49x
Therefore y = 49x
Answer:p = -1.25
Step-by-step explanation:
Simplifying
3 + 17p = -32 + -11p
Solving
3 + 17p = -32 + -11p
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '11p' to each side of the equation.
3 + 17p + 11p = -32 + -11p + 11p
Combine like terms: 17p + 11p = 28p
3 + 28p = -32 + -11p + 11p
Combine like terms: -11p + 11p = 0
3 + 28p = -32 + 0
3 + 28p = -32
Add '-3' to each side of the equation.
3 + -3 + 28p = -32 + -3
Combine like terms: 3 + -3 = 0
0 + 28p = -32 + -3
28p = -32 + -3
Combine like terms: -32 + -3 = -35
28p = -35
Divide each side by '28'.
p = -1.25
Simplifying
p = -1.25
19 = -1. The equation is false.
Answer:
look below
Step-by-step explanation:
y = 2x + 4
substitute x into the equation
so when x = -1
y = 2(-1) + 4
= -2 + 4
y = 2
(-1,2)
........................
when x = 0
y = 2(0) + 4
y = 4
(0,4)
......................
when x = 1
y = 2(1) + 4
= 2 + 4
y = 6
(1,6)
pop in the coordinates into the graph now
