Answer:

given us,

(x1y1) = (4,6)

(x2y2)= (1,10)

here

slope= (y2-y1)/ (x2-x1)

= (10-6)/ (1-4)

= 4/ (-3)

Step-by-step explanation:

4/ (-3)

How to find the area of a rectangle that is 2 4/5 feet by 3 1/4 feet

Harman [31]

Answer:

by simply multiplying these 2 dimensions.

9.1 ft²

Step-by-step explanation:

2 4/5 × 3 1/4 = (14/5) × (13/4) = (14×13) / (5×4) =

= (7×13) / (5×2) = 91/10 = 9.1 ft²

Whats the solution of <br> y = x +2 <br> 2x - 5y = 2

aleksandr82 [10.1K]

Answer:

x = -4, y = -2

Step-by-step explanation:

substitute for y

2x - 5(x + 2) = 2

distribute -5

2x -5x - 10 = 2

solve

-3x - 10 = 2

add 10 on both sides

-3x = 12

divide by -3

x = -4

now substitute for x in the equation y = x + 2

y = -4 + 2

y = -2

If 1 cm represents 30 km on a map and colorado is shown by a 20cm by 15 cm rectangle on the map, what is the approximate actual

zubka84 [21]

Answer:

20*30km = 600km

15*30km = 450km

600km * 450km = 270000 km^2

Step-by-step explanation:

assuming 1cm --- 30km causes that 2cm --- 60km, 3cm --- 90km, 4cm --- 120km etc. Notice that number of km's is 30 times greater than the number of cm's on a map

using this logic, you calculate both real dimensions of Colorado by multiplying 20*30 = 600 km and 15*30 = 450km

Then we use a formula of an area of a rectangle $A=a\cdot b$ assuming $a=600km, \ b=450km$ and get $A=600\cdot 450=270000km^2$ which is an actual area of Colorado

(6+8)^2=6^2+8^2 statement true

ddd [48]

this is false

(6+8)^2= 196

6^2+8^2=100

They are not equal so this is a false statement
