Hannah collects 16 pounds of paper to recycle. Sid collects 9 pounds of paper to recycle. How many puonds of paper dose Hannah collect than Sid?

Answer:

BC = 10

Step-by-step explanation:

Since this is an isosceles triangle

AC = BC

3x-5 = 2x

Subtract 3x from each side

3x-5-3x = 2x-3x

-5 = -x

Multiply each side by -1

5 =x

BC = 2x

     =2 *5

BC =10

Answer:

With speed of 18 feet per second the distance between the twins change.

Step-by-step explanation:

v1 is 10

v2 is -8

So, the difference is (10)-(-8)

which is 18.

Answer:

The distance of 2 feet with a speed of 10 feet per second.

Answer:x=-16

Step-by-step explanation:

Subtract 6 from both sides

x/8=-2

Multiply the number by 8 on both sides to get x by itself

x=-16

7x+10x-50=69

17x=69+50

x=7

Answer:

-1

Step-by-step explanation:

Use the slope intercept formula(y=mx+b) to find the slope of a line.

First, you will want to put everything into it's proper order, so you will get -y=-x+5.

You cannot have a negative y, so divide everything by -1 and you will get y=x-5.

1 is the slope. Now that you know that, you will want to find the reciprocal. To find the reciprocal, you will need to swap the numerator and the denominator and then swap it's sign, whether that is positive or negative..

The reciprocal of 1 is -1. -1 is the slope of the perpendicular line

Step-by-step explanation:

The surface area of a rectangular prism calculator gives us the answer: A = 2 * l * w + 2 * l * h + 2 * w * h = 2 * 8 ft * 6 ft + 2 * 8 ft * 5 ft + 2 * 6 ft * 5 ft = 236 ft² .

Answer:

A. y + 7 = 2/5(x + 4)

Step-by-step explanation:

so,

Answer:

should be (4a-5)x(4a+5)

Step-by-step explanation:

The factor of the function will be (4x - 3) and (3x + 1). The graph of the function is shown below.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The function is given below.

g(x) = 5x - 12x² + 3

Then the function can be written as

g(x) = - 12x² + 5x + 3

Then the factor of the function will be

g(x) = 0

Then we have

   - 12x² + 5x + 3 = 0

       12x² - 5x - 3 = 0

12x² - 9x + 4x - 3 = 0

    (4x - 3)(3x + 1) = 0

                         x = -0.33 and 0.75

Then the graph of the equation will be given below.

Answer:

A. f(x) = −2|x| + 1

Step-by-step explanation:

We want our exponential function to look like

y = ab^x.

Let a = the initial y-value.

Our initial value is the first number given for f(x). So, a = 3.

Let b = the number that is needed to go from 3 to 6 to 12 to 24 to 48.

We find b by division.

So, b = the next number divided by the previous.

So, b = 6/3 = 2.

We now plug in our values into the general formula above.

y = ab^x

Answer: y = (3)(2)^x

Answer:

Slope-intercept form is: y=mx+b. Where m = slope or rise/run & b = y-intercept or where the line crosses the y axis. So for 4x + 5y = 20 the slope intercept form is y = -4x/5 + 4.

Step-by-step explanation:

Answer:

y = -4/5x - 4

Step-by-step explanation:

4x + 5y = -20

-4x            -4x

5y = -4x - 20

divide it all by 5

y = -4/5x - 4

Answer:

An event can have a probability of 3/2  is not true

Step-by-step explanation:

The probability of an event happening is between 0 and 1 inclusive.

A probability of 1 means the event is certain to happen or 100%

You cannot have a probability greater than 1 so

An event can have a probability of 3/2 cannot happen

Answer:

x = 10

Step-by-step explanation:

Angles 12x and 10x + 20 are "vertical angles," meaning that they are identical (same value).  Therefore we can write the equation 12x = 10x + 20, which reduces to 2x = 20, or x = 10.

Answer:

x=10

Step-by-step explanation:

Hey There!

Those are a pair of vertical angles

Therefore they are congruent

congruent meaning identical in form

So we would setup and equation and because the angles are congruent the equation would be

12x=10x+20  and solve for x

Step 1 subtract 10x from each side

10x-10x cancels out

12x-10x=2x

now we have

2x=20

Step 2 divide each side by 2

2/2 cancels out

20/2=10

Therefore x=10

Answer:

y = 40

Step-by-step explanation:

For #7, we are told that y = 10 when x = 2

We are also told that 'y varies directly as x'. That means there is some constant number, k, so that

Formula -->  y = kx

Since y=10 and x= 2, we substitute those numbers into the formula.

We get 10 = k × 2.  

So k has to be 5, right?

k = 5

So what is y when x = 8?

Use the formula.

y=kx ---> That gives us y = k × 8. But we know k is 5.

                                 So y = 5 × 8 = 40

                                       y = 40

9514 1404 393

Answer:

  7. y = 5x; y = 40

  8. y = 1/3x; y = 8/3

Step-by-step explanation:

In the direct proportion equation y=kx, the value of k can be found as ...

  k = y/x . . . . . divide both sides by x to solve for k

__

7. k = 10/2 = 5

The equation is ...

  y = 5x

For x=8, the value of y is found using the equation:

  y = 5(8) = 40

__

8. Same deal, different numbers.

  k = 6/18 = 1/3

  y = 1/3x . . . . . the equation

  y = 8/3 . . . . . y for x=8
