Answer:
x = 20°
Step-by-step explanation:
In a circle, the measure of an inscribed angle is half the measure of the intercepted arc.
x = 40/2 = 20°
For this problem, I think the question is to find the values of x and y. Since there are two unknowns and two equations, this system may be solvable. But let's investigate first if the equations are independent.
y = 4x - 1 ----> eqn 1
12x = 3y + 7 ---> eqn 2
Substituting eqn 1 to eqn 2:
12x = 3(4x - 1) + 7
12x = 12x -3 + 7
12x - 12x = 7 - 3
0 = 4
It turns out that the system is not solvable because x cancels out. That means that the two given equations are dependent with each other.
Answer:
-5
Step-by-step explanation:
1) write it out:
3x-4=4x+1
2)combine like terms
Answer:
y = 2x + 1
Step-by-step explanation:
Since you have an equation and a point, all you need to do is substitute the coordinates into the equation and then solve for the y-intercept (or "b"):
y = mx + b
y = 2x + 2
(-3, -5)
-5 = 2(-3) + b
-5 = -6 + b
-5 + 6 = b
b = 1
Now you have your final equation:
y = 2x + 1
*Remember that parallel lines have the same slope, so finding a new slope is not needed!
23 3/4. because if it was 0.25, then you know that it is a quarter, 0.50 is half, therefore 0.75 is three quarters
