Answer:
x > -4
Step-by-step explanation:
Inequalities like these are solved the same way equations are solved, except when multiplying both sides you flip the less than/greater than sign:
3x + 7 > -x -9
3x + 7 - 7 > -x -9 -7 Subtract 7 from both sides
3x > -x -16
3x + x > -x -16 + x add x to both sides
4x > -16
> 
divide both sides by 4
x > -4
In this case the inequality sign did not have to be flipped since we never multiply both sides by a negative number.
Answer:
I hope you can see my writing clearly
Both functions can be expressed in the form of √2ˣ
f(x)=√(2ˣ)⁴ = √16ˣ
g(x)= √(2ˣ)⁶ = √64ˣ <-- these can be further broken down if required
Hope I helped :)
Answer:
d> 5.5
The graph in the attached figure
Step-by-step explanation:
we have
Solve the inequality for d
That means ---> isolate the variable d
Subtract 34 both sides
Divide by 12 both sides
The solution is the interval (5.5,∞)
All real numbers greater than 5.5
In a number line the solution is the shaded area at right of d=5.5 (open circle)
The value of d=5.5 is not included in the solution
The graph in the attached figure
No because there are two of the same inputs(x) (2,5) and (2,7)
