Your answer should be 126.4 (rounded)
Answer:
1. x<3
2. x<3
Step-by-step explanation:
2x-5<1
Move constant to the right side and change its sign
2x<1+5
Add the Numbers
2x<6
Divide both sides of the inequality by 2
x<3
3x+7<16
Move constant to the right side and change its sign
3x<16-7
Subtract the numbers
3x<9
Divide both sides of the inequality by 3
x<3
Answer:
first option
Step-by-step explanation:
If ( x + h) is a factor of f(x) then f(- h) = 0 , then
If (x + 1) is a factor of f(x) then f(- 1) = 0
f(- 1) = 7 - 5(- 1)³ - 10(- 1)² + 2(- 1)
= 7(1) - 5(- 1) - 10(1) - 2
= 7 + 5 - 10 - 2
= 12 - 12
= 0
Since f(- 1) = 0 then (x + 1) is a factor of f(x)
<span>"the sum of a number x and 4" is x + 4</span>
Then you divide that sum by 3.
(x + 4)/3
