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:
Step-by-step explanation:
When one variable depends on another variable according to a rule it is known as function:
For example if you want an output of 2 and the input value is 4. Then you will subtract 4 from x
We have to find x f(x).
x f(x) =?
f(x) = x-4
Now input value is: x= 3
x f(x)
3 (x-4)
3 (3-4)
3 -1
Now x= 4
x f(x)
4 (x-4)
4 (4-4)
4 0
Now x=5
x f(x)
5 (x-4)
5 (5-4)
5 1
Now x=6
x f(x)
6 (x-4)
6 (6-4)
6 2 ....
Answer:
The slant height is 9 meters.
Step-by-step explanation:
To determine the slant height, we will follow the steps below;
First, write down the formula:
Surface area = 2bs + b²
where b= the length of the base of the square pyramid
s = the slant height of the square pyramid
From the question given,
surface area of a square pyramid = 360 square meters
base length = 12 meters
We can now proceed to insert the values into the formula and then solve for s
Surface area = 2bs + b²
360 = 2(12)s + (12)²
360 = 24s + 144
subtract 144 from both-side of the equation
360 - 144 = 24s
216 = 24s
Divide both-side of the equation by 24
216/24 = 24s/24
9 = s
s = 9 meters
The slant height is 9 meters.
