what two numbers' sum=-4 and product=-2

Answers

Let a and b be the two numbers. Then

a + b = -4

a b = -2

Solve the second equation for b :

b = -2/a

Substitute this into the first equation:

a - 2/a = -4

Multiply both sides by a :

a² - 2 = -4a

Move 4a to the left side:

a² + 4a - 2 = 0

Use the quadratic formula to solve for a :

a = (-4 ± √(4² - 4(-2))) / 2

a = -2 ± √6

If a = -2 + √6, then

-2 + √6 + b = -4

b = -2 - √6

In the other case, we end up with the same numbers, but a and b are swapped.

Answers

Answer:

x=1.4

Step-by-step explanation:

1.4

Put the x’s on one side and the rest on the other then solve for x

So...

4x + x = 2 + 5

5x = 7

5x/5 = 7/5

X= 1.4

Note: when switching sides the sign’s
(+ and -) get switched. A positive sign becomes negative and vice versa

A family is calculating the cost for one semester of college next year. Each hour of class will cost $155. A scholarship gift of $64 can be deducted from costs. If h is the number of hours taken, and c is the total cost, which equation can be used to calculate the total tuition costs for a semester?

C=89h

You and your friend are in a canoe race. Your friend is a half mile in front of you and paddling 3 miles per hour. You are paddling 3.4 miles per hour. You are 8.5 miles from the finish line. How long will it take to catch up to your friend?

Answers

Answer:

To catch your friend you have to paddle for 1.25 hours

Step-by-step explanation:

Your friend is 0.5 mile in front of you and paddling 3 miles per hour. You are paddling 3.4 miles per hour.

Since the speed is the relationship between the space traveled by an object and the time used for it, then the distance is defined as:

distance= speed*time

Being x the time it takes to reach your friend, then your friend's position will be:

3miles per hour*x + 0.5 (since your friend  is 0.5 mile in front of you)

while your position is:

3.4 miles per hour*x

When you reach your friend the position of both should be the same. So:

3*x + 0.5= 3.4*x

Solving:

0.5= 3.4*x - 3*x

0.5= 0.4*x

0.5 ÷0.4= x

1.25= x

This means that to catch your friend you have to paddle for 1.25 hours

A 2 fl oz bottle of orange juice costs $8, and a 4 fl oz bottle of orange juice costs $12. Which is a better buy?

ANSWER= 4 fl oz bottle of orange juice that costs $12 is the better buy.

Answers

Answer:
Yes
Explanation:

Answer:

yes 4fl oz bottle of orange juice that costs $12 dollars is better to buy

Step-by-step explanation:

2 bottles of orange juice=8$

if you split 8$, you get 4$ that means each bottles of orange juice is 4$

so if you get 4 bottles of orange juice it is 4$x4$= 16$ The question says that 4 bottles cost 12$ its supposed to be 16$. So the 4 fl oz bottle of orange juice that costs 12$ dollars is better to buy.

1 bottle=4$               2x4=8$ (the first equation)    

1bottle=4$                4x4=16 (the second equation)   But the question says we got the bottle of orange juice for 12$ its supposed to be 16$ that is a huge discount. so yes the answer is correct.

Answers

Answer:

9/40

Step-by-step explanation:

He needs 5/8, he already has 2/5, so still needed is 5/8-2/5.

To add or subtract fractions, the denominators must be equal.

Simplest approach is to multiply them. 8 times 5 is 40, so 40 is the new denominator we need for both fractions.

So first we convert 5/8 to 25/40.

Then we convert 2/5 to 16/40.

Now we can subtract them:

25/40 - 16/40 = 9/40.

9/40 cannot be simplified so this is the final answer.

There are some basic rules you need to know to work with fractions. If above work is too fast, comment below for deeper explanation.

The answer is 9/40.

All you need to do is subtract 5/8 - 2/5 and to do that, you would need a common denominator. So just,

5 2
— —
8 5

Multiply the two bottoms to get 40 and do the same thing with the top that you did with the bottom so....

5 x 5 = 25
— —
8 x 5 = 40

2 x 8 = 16
— —
5 x 8 = 40

Subtract 25 - 16 = 9 and keep the denominator the same so 9/40 is your answer.

Enrique predicts that he can make additional money from sales of accessories and services for computer products sold by his store. The table at the right shows predicted percent returns for such sales. For example, if the store makes x dollars selling computer products, Enrique predicts the store will make 0.05x dollars from selling accessories. Part A In January and February of this year, the store made $2,500 from sales of accessories and services. Let x represent the amount the store will make from sales of computer products from March through December. Write an equation that represents the predicted amount y that the store will make from sales of accessories and services for the entire year. If Enrique predicts sales from accessories and services for the entire year will be $5,000, about how much money must be made from computer product sales from March through December? Explain.

Answers

Answer:

Following are the solution to this question:

Step-by-step explanation:

x was its full computer product revenue from March to December.  In january and february, the revenue towards products and services before x quantities for computer product revenues will happen between March to December is $2,500.  

Whenever x quantity is sold, then 0.05x quantity was sold for supplies and equipment.  

The sum of accessories to sell should be calculated, indeed, year-round.  

It helps us to split into two parts  

y = accessory sales in January and February + accessories sales in March and December  

Use item 2  

y = $2,500 + March to December accessories sale  

Now use sections 1 and 3  

y = $2,500 + 0.05x

The above equation rewriting gives  

y = 0.05x + $2,500 (a)  

This formula is compared with a standard y = mx+c interrupt slope  

We got a pitch of 0.05 and a pitch of $2,500.
