Answer:
<em>y = </em>
<em> x + 1 </em>
Step-by-step explanation:
If AB ⊥ CD , then ( 
) ( 
) = - 1
y = - 
x + 3
y - ( - 4) = ( x - 7) ⇔ <em>y = </em><em> x + 1 </em>
IDK if i have to explain again but
A. (-infinity, infinity)
B. (-infinity, -3]
C. (-infinity, -4)u(-4, 0)u(0, infinity)
those u's are the logic symbol
2. domain: [-6, -1)u(-1, 3]u [3, -infinity)
range: (-infinity, 4]
3a. 8x^2 + 17
3b. 32x^2 + 80x + 53
3c. I cant see the multiplication symbol
Answer:
-19
well i think it the answer
I’d say 6 I’m not very sure
Answer:
On a coordinate plane, a step graph has horizontal segments that are each 1 unit long. The left end of each segment is a closed circle. The right end of each segment is an open circle. The left-most segment goes from (negative 3, negative 5) to (negative 2, negative 5). Each segment is 1 unit higher and 1 unit farther to the right than the previous segment. The right-most segment goes from (4, 2) to (5, 2).
Step-by-step explanation:
The floor function graphs as horizontal segments 1 unit long, each 1 unit up from the segment to its left. It will have a closed circle at the left end of the segment, and an open circle at the right end.
Since 2 is subtracted from the floor of the x-value, the closed circle at the left end of the segment will have coordinates (x, x-2). The only offered choice meeting that condition is the 3rd choice listed here.
