What two numbers multiply to -30 and add to 1?

Answers

Answer 1
These numbers would be -5 & 6...

(-5)(6) = -30
-5 + 6 = 1
Answer 2

The products of two numbers involves multiplying them.

The two numbers are -5 and 6

Let the numbers be x and y.

So, we have:

[tex]\mathbf{x \times y = -30}[/tex]

[tex]\mathbf{x + y = 1}[/tex]

Make x the subject in [tex]\mathbf{x + y = 1}[/tex]

[tex]\mathbf{x = 1 - y}[/tex]

Substitute [tex]\mathbf{x = 1 - y}[/tex] in [tex]\mathbf{x \times y = -30}[/tex]

[tex]\mathbf{(1 - y)y = -30}[/tex]

Expand

[tex]\mathbf{y - y^2 = -30}[/tex]

So, we have:

[tex]\mathbf{y^2 -y - 30 = 0}[/tex]

Expand

[tex]\mathbf{y^2 -6y + 5y - 30 = 0}[/tex]

Factorize

[tex]\mathbf{y(y -6) + 5(y - 6) = 0}[/tex]

Factor out y - 6

[tex]\mathbf{(y + 5) (y - 6) = 0}[/tex]

Solve for y

[tex]\mathbf{y = -5\ and\ 6}[/tex]

Hence, the two numbers are -5 and 6

Jim bought a $576 TV with the cash in his wallet. He now has $137 in his wallet. Write and solve an equation that shows how much he originally had in his wallet.

Answers

576 - 137 = 439. so the TV was 439, The money he originally had was 576, and he now has 137 left. so m - c = t

Final answer:

Jim originally had $713 in his wallet before purchasing the TV. We found this by setting up the equation x - $576 = $137, which represents the situation before and after the purchase, and solving for x.

Explanation:

Jim bought a $576 TV with the cash in his wallet and now has $137 left. To find out how much money Jim originally had, we can write and solve a simple equation. Let's denote the amount of money Jim originally had as x. After buying the TV, he spent $576, so the money left is $137. This gives us the equation x - $576 = $137.

To solve for x, we add $576 to both sides of the equation, which gives us x = $137 + $576. Therefore, x = $713. So, Jim originally had $713 in his wallet before buying the TV.

Answers

It seems like there are only two problems here. Problem 1 is the one with Maddie throwing the baseball. Problem 2 deals with the cyclist. For some reason you threw in "What is the height of the ramp, to the nearest foot?" in the middle of the baseball problem. That seems like a typo?

======================================================
Problem 1 (baseball problem with Maddie)

a = 90
b = 90
c = unknown

Pythagorean Theorem
a^2+b^2 = c^2
90^2+90^2 = c^2
8100+8100 = c^2
16200 = c^2
c^2 = 16200
sqrt(c^2) = sqrt(16200)
c = 127.279220613579

If we round to the nearest ten, then we get 130. In other words, 127.279 is closer to 130 than it is to 120.

So it looks like "130 feet" (choice B) is the final answer.

Find two numbers whose difference is 168 and whose product is a minimum

Answers

The two numbers whose difference is 168 and whose product is a minimum will be -50 and 50.

What is the equation?

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, two numbers whose difference is 168 and whose product is a minimum.

Suppose the two numbers are x and Q respectively.

If x - Q = 100, then Q = 100 + x

The function of their product is minimum,

F(x) = xQ

F(x) = x (100 + x)

F(x) = x² + 100x

Find the equation's lowest point on a graph. At x, the lowest point is -50,

f(x) = -2500

If,

Q = 100 + x

Q = 100 + (-50)

Q= 50

The product of the number is,

xQ = 50 × -50

xQ = -2500

Thus, the two numbers whose difference is 168 and whose product is a minimum will be -50 and 50.

Li is making beaded necklaces for each necklace, she uses 27 spacers, plus 5 beads per inch of necklace length. Write an equation to find how many beads Li needs for each necklace.
A. Input variable
B. Output variable
C. Equation

Answers

Given that Li is making beaded necklaces for each necklace, she uses 27 spacers, plus 5 beads per inch of necklace length.

The equation to find how many beads Li needs for each necklace can be obtained as follows:

A. The input variable is the number of inches of the necklace length (x).

B. The output variable is the number of beads Li needs for each necklace (y).

C. The required equation is given by

y = 5x
Final answer:

The output variable B (total number of beads needs for each necklace) equals 27 (number of spacers used) plus 5 times the input variable A (length of the necklace in inches). The resulting equation is B = 27 + 5A.

Explanation:

In this question, we're trying to find out the total number of beads Li needs to create each necklace.

Let's define two variables:

A is the input variable, representing the length of the necklace in inches. B is the output variable, which stands for the total number of beads Li needs for each necklace.

Li uses 27 spacers for each necklace regardless of its length and there are 5 beads for every inch of necklace. Given these facts, we can create an equation as follows:

B = 27 + 5A

In this equation, 27 is the number of spacers used, while 5A indicates that 5 beads are strung for each inch of the necklace.

To use this equation, simply replace the variable 'A' with the desired length of the necklace in inches. The result will give the total number of beads Li needs for that particular length of necklace.

A share of stock in the Lofty Cheese Company is quoted at 251/4. Suppose you hold 30 shares of that stock, which you bought at 201/4. If you sell your stock at 251/4, how much profit do you get or lose?

Answers

You'll make a profit of $150.

To calculate the profit from buying and selling stocks, subtract the buying price per share from the selling price per share and then multiply by the number of shares. For 30 shares of the Lofty Cheese Company stock, the profit would total $150.

The question involves calculating the profit from buying and selling stocks. When selling the Lofty Cheese Company stock quoted at 251/4 per share, we need to calculate the profit based on the purchase price (201/4) and the selling price (251/4) for 30 shares.

To find the profit per share, subtract the buying price from the selling price:

Selling Price per Share = 251/4

Buying Price per Share = 201/4

Profit per Share = Selling Price - Buying Price = 251/4 - 201/4 = 5

Then, multiply the profit per share by the total number of shares:

Number of Shares = 30

Total Profit = Profit per Share times Number of Shares = 5 times 30 = 150

Therefore, you would realize a total profit of $150 by selling your 30 shares of the Lofty Cheese Company stock.

Find points on the line 3x+5y=15 that are equidistant from the coordinate axes.

Answers

Final answer:

Points on the line 3x+5y=15 which are equidistant from the coordinate axes are (15/8, 15/8) and (-15/8, -15/8).

Explanation:

To find points on the line 3x+5y=15 that are equidistant from the coordinate axes, we need a point where the x and y coordinates are equal because the distances to the x-axis and y-axis from any point (x, y) are |x| and |y|, respectively. Since the line is equidistant from both axes, we require |x| = |y|.

Substituting y for x in the equation of the line, we get 3x + 5x = 15, which leads to 8x = 15, and therefore x = 15/8. Since we are looking for points equidistant from the axes, we have to check the signs of x and y to ensure they are at equal distances from both axes. Thus, the possible points are (15/8, 15/8) and (-15/8, -15/8).
