In this complex number, assuming that the equation actually is <span>18- √-25</span>, the real part is already simplified. However, the imaginary part can be simplified by taking out "i" from the root using the relation i = <span>√-1. This is done below:

18 - </span><span>√-25
18 - </span>√(-1)(25)
18 - 5i

From the choices, the correct answer is 18 - 5i.

Select the equation that represents a lone in which intercepts the vertical axis at b. assume m≠0, b ≠ 0, and m≠b.
Tema [17]

Answer:

Option 'C' is correct.

Step-by-step explanation:

We know that the slope-intercept form of the line equation

y = mx+b

where

  • m is the slope
  • b is the y-intercept

We are given that an equation that represents a line in which intercepts the vertical axis at b, assuming m≠0, b ≠ 0, and m≠b.

As the line intercepts the vertical (y-axis) at b.

Therefore, 'b' is the y-intercept of the line.

Also, the slope is m.

Thus, according to the slope-intercept form of the line equation, the equation is:

y = mx+b

Therefore, option 'C' is correct.

Your friend is willing to pay no more than $17.000 on aneu cor.
belka [17]

Answer:

With rare exceptions, cars decrease in value with age. Depending on other factors, like accidents, repairs, or other damage, the value of a car may decrease even faster. If you borrowed money to buy a car, you might owe more on your car loan than its current value. When that happens, you have negative equity in the car. Some car dealers say you won’t be responsible for the remaining balance on your old car loan when you trade in your old car. But that might not be true. Dealers sometimes just roll over the negative equity into your new car loan, so you still end up paying it.

Step-by-step explanation:

Say you want to trade in your car for a newer model.

Your loan payoff is $18,000

Your car is worth $15,000

You have negative equity of $3,000. That must be paid if you want to trade in your vehicle. If the dealer promises to pay off the $3,000, it shouldn’t be included in your new loan.

But some dealers

add that $3,000 to the loan for your new car

subtract the amount from your down payment

or do both

vitfil [10]

Answer:

The better one is $6 for 24 oz bottle

Step-by-step explanation:

If it cost 4 dollars for a 12 oz bottle and that would cost 1 dollar per 3 oz but for the 6 dollar for a 24 oz bottle it would be 1 dollar per 4 oz so 6 dollars for a 24 oz bottle is better!

Elena plans to ride her bicycle 5 miles to a park and then ride several times
Aneli [31]

Option A

Elena need to ride around the  loop four or more times

<em><u>Solution:</u></em>

Given that Elena plans to ride her bicycle 5 miles to a park and then ride several times  around a loop in the park that is 3 miles long

Then she will ride the same way  home

She wants to ride a total of at least 22 miles

<em><u>Given inequality is:</u></em>

3t + 10 > 22

Where "t" is the number of times Elena rides around the loop

<em><u>Solve fot "t" in given inequality</u></em>

3t + 10 > 22

Subtract 10 both sides

3t + 10 - 10 > 22 - 10

3t > 12

Divide by 3 both sides

t > 4

The solution is all real numbers greater than or equal to 4

Which means 4 or more times

Therefore, Option A is correct.
