Answer:
x ≈ 11.1
Step-by-step explanation:
Using the sine ratio in the right triangle
sin59° = 
= 
( multiply both sides by 13 )
13 × sin59° = x , then
x ≈ 11.1 ( to the nearest tenth )
Answer:
y = -x + 2
Step-by-step explanation:
The point (0,2) is the y-intercept.
The equation of a line is y=mx + b.
The b variable represents the y-intercept.
The m variable represents the slope.
Substitute -1 for the slope and 2 for the y-intercept into the equation.
y = mx + b
y = (-1)x + (2)
y = -x + 2
Answer:
B: 4 solutions
Step-by-step explanation:
Combining the two equations results in 2x² = 52, or x² = 26.
This equation has two solutions: x = ±√26.
As before, x² = 26. If we substitute 26 for x² in the 1st equation, we get:
26 - 4y² = 16, or 4y² = 10, or y = ±√5/2. Again: two solutions.
If we take x to be +√26, y could be ±√(5/2).
Check: is ( √26, √(5/2) ) a solution of the system?
Subbing these values into the first equation, we get:
26 - 4(5/2) = 16. Is this true?
Then 10 = 10. Yes.
Through three more checks, we find that this system has FOUR solutions.
8 + (3 + t) is the answer
