Step-by-step explanation:
cos(y°) = 8/13
y° = arccos(8/13) ≅ 50°
Answer:
(x-1)²+(y+4)²=3²
Step-by-step explanation:
The formula for a circle on a graph is standard form is:
(x – h)² + (y – k)² = r²
(h,k) being the center point of the circle.
r=radius
The answer for the equation of this circle in standard form is:
(x-1)²+(y+4)²=3²
Answer:
(x, y) = (-1/4, -3/4)
Step-by-step explanation:
1. Write as a system
2x + 2y = 14x - 2y = -2
2. Eliminate one variable by adding the equations
2x + 2y = -2
14 x - 2y = -2
3. Divide both sides by 16
16x = -4
4. Substitute the value of x into the equation.
x = -1/4
5. Solve the equation
2(-1/4) + 2y = -2
6. A possible solution is
y = -3/4
7. Check the solution
(x, y) = (-1/4, -3/4)
8. Simplify the expression
2(-1/4) + 2(-3/4) = 14(1/4) - 2(-3/4) = -2
9. The ordered pair is a solution
-2 = -2 = -2
10. (x, y) = (-1/4, -3/4)
