after you remove parentheses you do those steps
Answer: f(x) = 64 * (3/4)^x
Step-by-step explanation: f(x)=ab^x
When x=0 f(x) = 64
64 = ab^0
b^0 =1 so
64 =a
f(x)=64 b^x
When x=1 f(x) = 48
48 = 64 *b
Divide by 64
48/64 =b
6/8 =b
3/4 =b
f(x) = 64 * (3/4)^x
Answer:
x(5+x)
Step-by-step explanation:
Answer:
y = -1/5x + 3/5
Step-by-step explanation:
Step 1: Find slope
<em>Take the negative reciprocal of the other line</em>
m = -1/5
y = 1/5x + b
Step 2: Find <em>b</em>
1 = -1/5(-2) + b
1 = 2/5 + b
b = 3/5
Step 3: Rewrite perpendicular equation
y = -1/5x + 3/5
