Answer:
d=-18
a=51
x=-4
c=13/3
Step-by-step explanation:
1. subtract 6 from both sides
divide both sides by -2
2. add 2 to both sides
times both sides by 3
3. times both sides by 4
divide both sides by 9
4. multiply the 10 out into the parenthesis add the 10c and 2c to get 12 c
add 40 to both sides
divide both sides by 3
Answer:
a=8 b=3/2
Step-by-step explanation:
so here a is the initial value which 8
then we can plug in 2 for x and 18 for f(x) to find b
f(x)=8*b^x
18=8*b^2
18/8=b^2
9/4=b^2
b^2=(3/2)^2
b=3/2
