<span>3[x + 3(4x – 5)] = 15x – 24
3x + 12x - 15 = 15x - 24
15x - 15 = 15x - 24

The answer is C) y=14(0.9)ˣ and it's an exponential function
PROOF
Give to x the respective values of x & calculate y, using y = 14(0.9)ˣ
x | y
---------|---------
0 | 14(0.9)⁰ = 14
1 | 14(0.9)¹ = 12.6
2 | 14(0.9)² = 11.34
3 | 14(0.9)³ = 10.206
4 | 14(09)⁴ = 9.1845
Answer:
0.722
Step-by-step explanation:
First of all add up the sections 1 to 8 to make sure they add to 360
They do actually.
- 1 10
- 2 20
- 3 30
- 4 40
- 5 50
- 6 60
- 7 70
- <u>8 80</u>
Total 360
This is an area question. Every time you spin the spinner, it must come to an area labeled 1 to 8.
You could do this by setting up a ratio of each section and subtract the section for 3 and 7. That's the long way.
The shorter way is to add up the degrees for 3 and 7 and subtract them from the total (360)
Area 3 + area 7 = 30o + 70o = 100 degrees.
So the probability of landing in 3 or 7 is 100 / 360 = 0.278 (rounded)
The probability of Not landing on 3 or 7 is 1 - 0.278 = 0.722
Answer:
<h2>
$65</h2>
Step-by-step explanation:
Step one:
we are told that the ratio of Kailyn's money to Nathan's money is
4:9,
Nathan has $45, let Kailyn's money be x
therefore
4/9=x/45
cross multiply we have
9x=45*4
9x=180
divide both sides by 9
x=180/9
x=20
Kailyn's money is $20
Together they have =20+45= $65
That solid figure that you are is a square.
