Answer:
G
Step-by-step explanation:
Answer:
<A = 41.4°
Step-by-step explanation:
Recall, SOH CAH TOA
Reference angle = <A
Hypotenuse length = 8
Adjacent length = 6
Since Hypotenuse and Adjacent are involved, we would apply CAH, which is:
Cos A = Adj/Hyp
Plug in the values
Cos A = 6/8
Cos A = 0.75

A = 41.4096221° ≈ 41.4° (nearest tenth)
Y=x+4 y=0
0=x+4
*you put 4 on the other side with minus before this number*
-4=x
x=-4
We have been given the parent function as y=\frac{1}{x}.
We need to write the equation when the graph of this function is shifted left by 6 units.
We know the rule that when we add a constant "c" to the x value of the parent function then the graph will shift left by 'c' units.
Here the parent function is shifted left by 6 units. Hence, we must add 6 to the x.
Therefore, the equation of the parent function becomes

Label your unknown numbers
I'm calling them x and y
x+y=21
5x+2y=66
find a relation of x and y
y=21-x
substitute this into your second equation
5x+2 (21-x)=66
simplify to find x
5x+42-2x=66
3x+42=66
3x=24
x=24/3=8
apply your findings to find the second number
8+y=21
y=13
check your answer
5 (8)+2 (13)=66
40+26=66
we now know that the first number x is 8
and the second number y is 13
