Answer:
y = 4/3
Step-by-step explanation:
y = 3^x+1
Substitute -1 for x.
y = 3^(-1)+1
y = 1/3 + 1
y = 1/3 + 3/3
y = 4/3
Answer:
Increasing the number of people allows more variety and diversity, which makes the sample more accurate.
Answer:
x<5
Step-by-step explanation:
Move all like terms to one side:
2x<14-4
Simplify:
2x<10
Solve:
x<10/2
x<5
:)
To solve for a variable, you need to get it (x) by itself.
x² - 14 + 31 = 63 Add 31 to -14
x² + 17 = 63 Subtract 17 from both sides of the equation
x² = 46 Square root both sides
x =
![\pm \sqrt{46}](https://tex.z-dn.net/?f=%5Cpm%20%5Csqrt%7B46%7D%20)
Check your work by plugging in
![\sqrt{46}](https://tex.z-dn.net/?f=%20%5Csqrt%7B46%7D%20)
for x and then
![- \sqrt{46}](https://tex.z-dn.net/?f=-%20%5Csqrt%7B46%7D%20)
.
![\sqrt{46}](https://tex.z-dn.net/?f=%20%5Csqrt%7B46%7D%20)
² - 14 + 31 = 63 Square
![\sqrt{46}](https://tex.z-dn.net/?f=%20%5Csqrt%7B46%7D%20)
46 - 14 + 31 = 63 Subtract 14 from 46
32 + 31 = 63 Add
63 = 63
![- \sqrt{46}](https://tex.z-dn.net/?f=-%20%5Csqrt%7B46%7D%20)
² - 14 + 31 = 63 Square
![- \sqrt{46}](https://tex.z-dn.net/?f=-%20%5Csqrt%7B46%7D%20)
46 - 14 + 31 = 63 Subtract 14 from 46
32 + 31 = 63 Add
63 = 63
So,
x is
and ![- \sqrt{46}](https://tex.z-dn.net/?f=-%20%5Csqrt%7B46%7D%20)
.
