Answer: -7/-3.

Step-by-step explanation: In this problem we're asked to find the slope of the line that passes through the points (4,3) and (1,-4).

Using our slope formula, we take the second y minus the first y which in this case is -4 - 3 over our second x minus our first x which in this case is 1 - 4.

-4 - 3 is -7 and 1 - 4 is -3.

So the slope of this line is -7/-3.

Answer:

-7/-3

Step-by-step explanation:

Slope is represented as m

m = Rise/Run =( Y2 - Y1) / (X2 - X1)

m = (-4 -3) / (1 - 4)

m = -7 / -3

The negative sign (minus) will cancel out

Therefore,

m = 7 / 3

m = 2 whole number, 1/3

The sum of Jim's weight and Bob's weight is 180 pounds. If you subtract Jim's weight from Bob's weight, you get half of Bob's we

Furkat [3]

Answer:

120 pounds

Step-by-step explanation:

We can use systems of equations to solve this problem. Assuming j is Jim's weight and b is Bob's weight, the equations are:

j + b = 180

b - j = 1/2b

Let's get b - j = 1/2b into standard form (b, then j, then the equal sign, then the constant.)

$b - j = \frac{b}{2}\\\frac{b}{2} - j = 0$

Now we can solve using the process of elimination.

$b + j = 180\\\\\frac{b}{2} - j = 0\\\\b + \frac{b}{2} = 180\\\\b + b \cdot 2 = 180\cdot 2\\3b = 360\\b = 120$

Now we know how much Bob weighs, for fun, let's find Jim's weight by substituting into the equation.

$120 + j = 180\\j = 180-120\\j = 60$

So Bob weighs 120 pounds and Jim weight 60 pounds.

Hope this helped!

Solve 5√3 as the square root of a single number

Andreyy89

Answer:

/75

Step-by-step explanation:

As I couldn't take the radical symbol I used this - "/".

5 /3

If 5 has to come in the radical sign it has to be squared

So, /25 × /3

/25×3

/75
