Step-by-step explanation:
Sum of opposite angles are supplementary,
x + 60 + 3x = 180
4x + 60 = 180
4x = 180 - 60
4x = 120
x = 120 / 4
x = 30

Question 1
Which statement about the system of equations y = 3x + 9 and y = 3x – 4 is true?
A. No solution
B. Infinite solutions
C. Exactly one solution
D. Different y-intercepts so there are two solutions
Answers
Answer:
A. no solution
Step-by-step explanation:
y = 3x + 9
y = 3x - 4
Let's solve this.
We can see that both equations equal y, so we can set them equal to each other.
3x + 9 = 3x - 4
Combine like terms.
[add 4 to both sides]
3x + 13 = 3x
[subtract 3x from both sides]
13 = 0
This statement is not true; therefore, there is no solution.
If we look at the graph below, we can see the lines are parallel. Parallel lines will never intersect and have no solution in a system of equations.

Step-by-step explanation:
From the question we are told that:
Height of Eagle [tex]h=40ft[/tex]
Angle of depression [tex]\theta=35\textdegree[/tex]
Generally the trigonometry equation for diagonal X is mathematically given by
[tex]Cos\theta \textdegree=\frac{Adjacent}{Hypotenuse} }[/tex]

Determine whether the Law of Cosines or the Law of Sines is needed to solve the triangle a = 11, b = 13, c = 7
Answers
Answer:
Step-by-step explanation:
Use the Law of Cosines:
c^2 = a^2 + b^2 - 2ab*cos C becomes
7^2 = 11^2 + 13^2 - 2(11)(13)cos C.
Once you have cos C, and then side c, you can use the Law of Sines to find the other two interior angles.
6. Which equation written in slope-intercept form represents the trend line 1 shown on the scatter plot below?

9514 1404 393
Answer:
B
Step-by-step explanation:
The line has a y-intercept of 40 (in agreement with all answer choices). It goes through the point (6, 30), so has a "rise" of -10 for a "run" of 6. The slope is ...
m = rise/run = -10/6 = -5/3
The equation with a slope of -5/3 is the one shown in choice B.
