Answer:
(3,-1)
Step-by-step explanation:
So we have the system of equations:
As directed, add straight down. The y-variable will cancel:
Now, divide both sides by 5. The left cancels:
So x is 3.
Now, substitute 3 for x in either of the equations:
Substitute 3 for x:
Multiply:
Subtract 9 from both sides:
So, our answer is: x=3, y=-1 or (3,-1).
And we are done :)
Answer:
The answer is y=2
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
The arc XZ is twice the measure of the inscribed angle XYZ , that is
arc XZ = 2 × 60° = 120°
The complete circumference = 360° , thus
arc XYZ = 360° - arc XZ = 360° - 120° = 240° → B
Answer:
C. (2,4)
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
We can subtract both sides of the equation by 3, getting 3 + p - 3 = 8 - 3.
Then we can evaluate, getting p = 8 - 3 = 5.
