Answer:
Im not sure but I think its -5
Answer:
9x+8 and 3x+5.
Explanation:
Let the first polynomial = 9x + 8
Let the second polynomial be a+b

Similarly:

Thus, the second polynomial = 3x+5
Therefore, the two polynomials whose difference is 6x+3 are 9x+8 and 3x+5.
Answer:
- Hence, 75.52 percent of the u.s. population had internet access in 2005.
- After 25 years or in the year 2015 89% have internet access.
Step-by-step explanation:
the percent p of the u.s. population with internet access is given by:
25 p-34 t=1378
where t is the number of years after 1990.
- We are asked to find what percent of the u.s. population had internet access in 2005 i.e. we need to find the value of p after 15 years i.e. t=15.
⇒ 25p-34×(15)=1378
⇒ 25p-510=1378
⇒ 25p=1378+510
⇒ 25p=1888
⇒ p=75.52
Hence, 75.52 percent of the u.s. population had internet access in 2005.
- Next we are asked to find in what year will 89% have internet access?
i.e. we have to find the value of t when we are given p=89
⇒ 25×89-34t=1378
⇒ 2225-34t=1378
⇒ 2225-1378=34t
⇒ 847=34t
⇒ or 34t=847
⇒ t=24.9112≈25
Hence after 25 years 89% will have internet access.
i.e. in the year 2015 89% will have internet access.
Use the substitution method
Answers :
g(x)= -3x+1
a. g(10)= -3(10)+1
Mutiply first = -30
-30+1= -29
<em>g(10)= -29</em>
b. g(-2)= -3(-2)+1
Negative sign and negative sign = positive sign
-3(-2)= 6
6+1= 7
<em>g(-2)= 7</em>
a.
f(x)=x^2+7
f(3)= 3^ 2+7
3*3 because of the exponent. 3*3= 9
9+7= 16
<em>f(3)= 16</em>
d.
f(a)= a^2+7
a*a= a^2
a^2+7
<em>f(a)= a^2+7</em>
