Find the slope of the line containing the two points (1,-1) and 7-5,-3). (1 point)
katrin [286]

Answer:

m = \frac{-2}{3}

Explanation:

Given

Points: (1,-1) and (-5,3)

Required

Determine the slope

The slope of a line is represented by m and is calculated as thus;

m = \frac{y_1 - y_2}{x_1 - x_2}

Where

(x_1,y_1) = (1,-1)

(x_2,y_2) = (-5,3)

Substitute these values in the given formula

m = \frac{-1 - 3}{1 - (-5)}

m = \frac{-1 - 3}{1 +5}

m = \frac{-4}{6}

Simplify fraction

m = \frac{-2}{3}

Hence, the slope of the line is m = \frac{-2}{3}

Nikitich [7]

Answer:

<h2>32 slices</h2>

Explanation:

Step one:

given data

we are told that 1 large pizza can be cut into 8 even slices

Required

we want to find how many slices are there in 4 large pizzas

Step two:

so if 1 pizza has 8 slices

       4 pizza will have x

cross multiply we have

x= 8*4

x=32 slices

What is the speed of an object at rest
sammy [17]
The speed of an object is measured by calculating the distance it travels per unit time.
The formula in Physics for calculating speed is = distance/ time.

Since an object at rest is not covering any distance, the speed is always assumed to be 0 m/s.

Greeley [361]

Answer:

90 m/s

8100 m

Explanation:

Given:

v₀ = 0 m/s

a = 0.5 m/s²

t = 3 min = 180 s

Find: v and Δx

v = at + v₀

v = (0.5 m/s²) (180 s) + 0 m/s

v = 90 m/s

Δx = v₀ t + ½ at²

Δx = (0 m/s) (180 s) + ½ (0.5 m/s²) (180 s)²

Δx = 8100 m
