Answer:
(x,y)=(1,5)
Step-by-step explanation:
6x+3y=21/*2
-12x+y=-7
12x+6y=42 (1)
-12x+y=-7 (2)
(1)+(2): 7y=35
-12x+y=-7
y=35/7
-12x+y=-7
y=5
-12x+5=-7
y=5
-12x=-7-5
y=5
-12x=-12
y=5
x=-12/(-12
y=5
x=1
(x,y)=(1,5)
Answer:
What do you want us to answer?
Step-by-step explanation:
It would be 2^12 (to the twelfth power) What you do is you multiply the power that's inside of the parentheses and the one on the outside. Since they are both negative, the power will end up being positive. And if you need to multiply it out, it would be 4096.
You need to <span>draw the diagram to understand the problem easily. Teh diagram will show the right triangle, acute angle with the base 7º, height is 663 m, and "x" is the base of the triangle.
using the tangent ratio:
tan</span>Θ = opposite / adjacent
<span>
tan7º = 663 m / x
x = 663 m / tan7º
x = 5,399.7 m
change m to km. 1,000 m = 1km
5,399.7m * 1km/1,000 m = 5,399.7 km/1000 = 5.3997 km or 5.4 km
B. 5.4 km </span>
3:4
180 / 6 = 30 / 10 = 3
240 / 6 = 40 / 10 = 4
3 = website sales
4 = store sales
website : store
=
3 : 4
