Answer: The Horizontal line at 5
Step-by-step explanation: For Y to be a function, there cannot be different points on the same x value. The horizontal line is the only one that has one y value per x value.
Hope this helps!
When you multiply the equation out and you simplify like terms you get.
2x^2 + 6xy + 4y^2
Answer:
First statement is correct
Step-by-step explanation:
Segment AB is tangent to the circle C because 
Answer:
C
Step-by-step explanation:
To find the x-intercept, set y to equal 0 and solve for the equation 0=-2x-2.
2=-2x
x=-1
x-int: (-1,0)
This eliminates choices B and D.
To find the y-intercept, set x to equal 0 and solve for y.
y=-2(0)-2
y=-2
y-intercept:(0,-2)
The only choice with both these values is C.
Answer:
no solution
Step-by-step explanation:
given the 2 equations
- 2x + 3y = 18 → (1)
3y = 2x + 5 → (2)
we can substitute 3y = 2x + 5 into equation (1)
- 2x + 2x + 5 = 18 ( collecting like terms gives )
5 = 18 ← not possible
Hence the system of equations has no solution
