Answer:
5/9
Step-by-step explanation:
F(-2)for f(x)=5•3^x
Let x = -2
f(-2)=5•3^(-2)
= 5 * 1/3^2
= 5 * 1/9
= 5/9
Answer:
-10 = x
Step-by-step explanation:
5=7+x/5
Subtract 7 from each side
5-7=7-7+x/5
-2 = x/5
Multiply each side by 5
-2 *5 = x/5 *5
-10 = x
So you have the ratio of 9:2.
The video has 18 thumbs up votes with the ratio being thumbs up to thumbs down.
9 in relation to 18 is times 2 so it makes since to times 2 by 2.
Therefore the ratio would be 18:4 which means there would be 4 thumbs down.
x and x+4 are the numbers
3x=2(x+4)
3x=2x+8
3x-2x=8
x=8
x+4=12
