Answer:
The best estimate for the solution of the system of equations is the ordered pair (7, 0.5)
Step-by-step explanation:
The way to solve this problem is to take a deep look into the picture, where we can see that the interception between the lines occurs right in x=7. thus, eliminating the first choice.
Next, we can see that the interception is somewhere far from the 'x' axis, hence 'y' variable can not be zero in this point.
Thus, we have our possible solution, without knowing anything else, the ordered pair (7, 0.5).
Remember, a system of equation has a solution when an interception occurs between its equations
For this case we can use the following trigonometric relationship:
tan (theta) = y / x
Substituting values we have:
tan (theta) = (4/5) / (3/5)
Rewriting we have:
tan (theta) = 4/3
Clearing theta:
theta = Atan (4/3)
theta = 53.13 degrees
Answer:
the approximate value of teta is:
theta = 53.13 degrees
[8/(2x-2)=(8+6)/(3x)
8/(2x-2)=14/(3x)
14(2x-2)=8(3x)
28x-28=24x
x=7
So by using the similarity of the sides, we can make ratios that can give is the value of x.<span />
Answer:
I think 32 because 32/4=8
Step-by-step explanation:
Go on a calculator
cosine=Adjacent/Hypotenuse
Cosine=6/ 3 the square root of 5
reduce to 1/square root of 5 which is your answer...so the answer is B)
Hope this helps!!
