Answer:

  • 7/3
  • -3
  • y = 7/3x - 3

Step-by-step explanation:

1) The slope is given by the formula ...

  m = (y2 -y1)/(x2 -x1)

  m = (4 -(-3))/(3 -0) = 7/3

__

2) The y-intercept is the point where x=0:

  (x, y) = (0, -3) . . . . . y = -3

__

3) Then the slope-intercept equation is ...

  y = mx + b . . . . . . . line with slope m and y-intercept b

  y = 7/3x -3

The common factors of 4p3mn2 and 2pm2n3 is​
pantera1 [17]

Given:

The given terms are

4p^3mn^2 and 2pm^2n^3

To find:

The common factors of given terms.

Solution:

We have,

4p^3mn^2 and 2pm^2n^3

The factor forms are

4p^3mn^2=2\times 2\times p\times p\times p\times m\times n\times n

2pm^2n^3=2\times p\times m\times m\times n\times n\times n

The common factors are 2, p, m, n, n. So,

Common factors = 2\times p\times m\times n\times n

                            = 2pmn^2

Therefore, the common factor of given terms is 2pmn^2.

A bag contains 55 coins of $1 and ¢50 denominations. Find the number of coins of each denomination, if the total amount in the b
DerKrebs [107]

Answer:

Number of $1 coins are 25 and number of 50 cent coins are 30.

Step-by-step explanation:

Let's set up the equations.

Let there are x number of $1 coins

There are y number of 50 cent coins

So, x+y =55

1 x+0.50 y =40

Solve the equations for x and y.

Solve the first equation for y.

y=55-x

Substitute y as 55-x into the second equation.

1 x+0.50(55-x)=40

Solve the equation for 'x'.

Distribute the 0.50 to get rid the ( ).

1 x+27.5-0.50 x= 40

Combine like terms

0.50 x +27.5=40

Subtract both sides 27.5

0.50 x =12.5

Divide both sides by 0.50

x=25

Now, plug in x as 25

y=55-25

y=30

So, number of $1 coins are 25 and number of 50 cent coins are 30.

Bily is helping to make piZzas for a school function. He's made 25 pizzas so far His principal asked him to make at least 30 piz
GrogVix [38]

The answer is Option B

We know that this inequality doesn't require any negative number division, there's no need to switch the ≤'s into ≥'s.

So now, all we have to do is subtract 25 from every number, giving us <u>5≤x≤50</u>

Manny and Susan have an egg carton full of eggs to use for their science project.
scoray [572]

Answer:

5/6

Step-by-step explanation:

1/3 + 1/2 is a simple addition fraction problem.

You'd find the LCM (lowest common denominator) which is 6. First, we'll take 1/3 which the denominator becomes 6. You see one side has been basically multiplied by 2, so you'd do it to both sides, giving us 2/6. Next, we do the same thing with 1/2. 2 -> 6 1 -> 3. 3/6. So finally, we have 3/6 + 2/6, which is 5/6.
