Answer:
cos 20 degree is equal to 12/x
option C is equal
Answer:
x=2,y=2
Step-by-step explanation:
This question is a simultaneous equation
So let's solve
3x+y=8...(1)
2x+2y=8....(2)
Multiply (1) by 2
6x+2y=16...(3)
Substrate (2) From (3)
4x=8
Let's make x the subject of formula by dividing both sides by 4
x=2
So let's substitute the value of x into (1)
3x+y=8
3(2)+y=8
6+y=8
y=8-6
y=2
Therefore x is 2,y is 2

ANSWER
A) For all x > 0 the graph will be higher.
EXPLANATION
Jack's graph has equation
y=2x
This graph passes through the origin and has slope 2.
Nina's graph is y=5x.
This graph also passes through the origin and has slope 5.
Since 5 is greater than 2, for all x>0, Nina's graph will be higher.
