Answer:

$-\frac{5}{4}$

Step-by-step explanation:

The slope of a graph is the rate of change between two points. To find the slope in a graph you use: $\frac{rise}{run}=\frac{y}{x}$

The y goes down by 5 and right by 4 so it'll be $-\frac{5}{4}$

Also: If the line is going down the slope is always negative and vise versa

The weight of water is 62 1/2 per cubic feet. Water that weighs 325 lbs will fill how many cubic feet

yulyashka [42]

Water that weighs 325 lbs will fill 5.2 cubic feet.

Step-by-step explanation:

This is a simple question of cross multiplication

DATA:

1. The weight of water for 1 cubic feet is 62.5

2. The weight of water for 'X' cubic feet is 325

3. To find x, form an equation:

Cubic feet : Weight of water

1 : 62.5

X : 325

4. Cross multiply

X x 62.5 = 1 x 325

62.5X = 325

5. Make X the subject

X = $\frac{325}{62.5}$

6. Solve to find X

X = 5.2 cubic feet

Therefore, water that weighs 325 lbs will fill 5.2 cubic feet.

There are 15 people on a basketball team, and the coach needs to choose 5 to put into

snow_lady [41]

Answer:

The coach can do this in 3,003 ways

Step-by-step explanation:

Here, the coach needs to select a team of 5 from a total of 15 players

Mathematically, the number of ways this can be done is simply 15 C5 ways

Generally, if we are to select a number of r items from n items, this can be done in nCr ways = n!/(n-r)!r!

Applying this to the situation on ground, we have;

15C5 = 15!/(15-5)!5! = 15!/10!5! = 3,003 ways

Simplify the given expression below: (7-3i)•(2-i)

Dimas [21]

when multiplying two binomials together we use the F.O.I.L. method:

First

Outer

Inner

Last

(7-3i)(2-i)

First: 7 * 2 ..... Outter: 7 * -i .... Inner: -3i * 2 ...... Last: -3i * -i

First: 14 ...... Outter= -7i ..... Inner: -6i .... Last: 3i^2

putting this together we get 14-7i-6i+2i^2

We combine like terms and end up with 2i^2-13i+14
