Answer:

The larger package is twice as heavy

Step-by-step explanation:

first make 1 1/4 into 5/4 and then multiply the top and the bottom by 2 to get a common denominator of 8. you will end up with 10/8. you can then subtract 5/8 from 10/8, leaving you with 5/8.

Simplify. (5x2+2x−5)−(3x2+3x+1)

guapka [62]

Answer:

x² - x - 6

Step-by-step explanation:

Step 1: Write expression

(5x² + 2x - 5) - (3x² + 3x + 1)

Step 2: Distribute negative

5x² + 2x - 5 - 3x² - 3x - 1

Step 3: Combine like terms (x²)

2x² + 2x - 5 - 3x - 1

Step 4: Combine like terms (x)

x² - x - 5 - 1

Step 5: Combine like terms (constants)

x² - x - 6

A=4pi r squared solve for r squared

maxonik [38]

A=4pir^2
divide both sides by 4pi
$\frac{A}{4pi}=r^2$
$r^2= \frac{A}{4pi}$

The equation of a line is 5x − 3y = 6. Which is the y-intercept of the line?

oksian1 [2.3K]

Answer:

y - intercept. = 2.

Step-by-step explanation:

Given : The equation of a line is 5x − 3y = 6.

To find : Which is the y-intercept of the line.

Solution : We have given 5x − 3y = 6.

Equation of line y = mx +b

Where , m = slope , y intercept = b

Now we convert the 5x − 3y = 6 in line form y = mx +b

5x − 3y = 6

On subtracting both sides by 5x

-3x = - 5x + 6

On dividing both sides by - 3.

x = $\frac{5x}{3}+2$ .

We cans see m = $\frac{5}{3}$ , y - intercept. = 2.

Therefore, y - intercept. = 2.

If a and b are the roots of 11x^2-4x-2=0 then compute the product: (1+a+a^2+...)(1+b+b^2+...)

lisov135 [29]

Answer:

11/5

Step-by-step explanation:

FirLet a and b be the roots of 11x^2-4x-2=0

Now $(1+a+a^2+\cdots)(1+b+b^2+\dcots)=\frac{1}{1-a}\cdot \frac{1}{1-b}\\=\frac{1}{(1-a)(1-b)}=\frac{1}{1-(a+b)+ab}$

Dividing the quadratic equation by 11 we have

$x^2-\frac{4}{11}x-\frac{2}{11}=0.$

Now the sum of the roots is the minus of the coefficient of x and the product of the roots is the constant. Therefore

$a+b = 4/11 \\ab = -2/11$

and we have

$\frac{1}{(1-a)(1-b)}=\frac{1}{1-\frac{4}{11}-\frac{2}{11}}\\=\frac{1}{(5/11)}=\frac{11}{5}$
