<span>y=4x−1;y=2x−5
Step: Solve y=4x−1 for y:
Step: Substitute 4x−1 for y in y=2x−5:
y=2x−5
4x−1=2x−5
4x−1+−2x=2x−5+−2x(Add -2x to both sides)
2x−1=−5
2x−1+1=−5+1(Add 1 to both sides)
2x=−4
2x/2=−4/2(Divide both sides by 2)
x=−2
Step: Substitute−2 for x in y=4x−1:
y=4x−1
y=(4)(−2)−1
y=−9(Simplify both sides of the equation)
<u>Answer:</u>y=−9 and x=−2</span>
Answer:
If I am not wrong I think the answer is the last one
Step-by-step explanation:
Since you are working with exponents and roots you would add the exponents together. The ninth root of x is equal to x^(1/9) and since you are using it four times your answer would be x^(4/9).

Here,

The potential rational roots are,


From, the given options only
satisfies.
Answer:
2.5 km
Step-by-step explanation:
First, find the area of the region:
- A circular region has a population of about 15,500 people;
- A population density of about 775 people per square kilometer.
So, there are
square kilometers.
Now, let x kilometers be the radius of the circular region, then

To the nearest tenth this is 2.5 km.
