Answer:
C, no it doesn’t make it a triangle
Step-by-step explanation:
all triangles angles equal 180
30 + 50 + 120 = 200 so no it’s not a triangle since it doesn’t equal 180
Step-by-step explanation:
∠W and ∠Z are supplementary
Answer: (C) y= x − 2
Explanation:
y=x-2 is the choice that satisfies all the points in the table. This can be verified case by case:
y=x-2
(-3,-5): -5 = -3 -3
(-1,-3): -3 = -1 - 2
(1,-1): -1 = 1 - 2
(3, 1): 1 = x - 2
(5,3): 3 = 5 - 3
Answer:
(-1,6) ; (-2,11)
Step-by-step explanation:
y= x^2-2x +3
y= -5x + 1
the best way to proceed is substitute the value of y shows in the second equation in the first equation (general rule: substitute the value shows in the linear equation in the quadratic equation)
-5x + 1 = x^2-2x+3
x^2 +3x + 2 = 0
(x+2)(x+1) = 0
x = -2
x = -1
Solution 1
x = -1
y = 5 + 1 = 6
Solution 2
x = -2
y = 10 + 1 = 11
