Answer:
6, 1, 8, -16
Step-by-step explanation:
For each input we divide it by 2 and then add 3 to get the output:
6/2+3=3+3=6
-4/2+3=-2+3=1
For each output we subtract 3 and multiply it by two to get the input:
(7-3)*2=4*2=8
(-5-3)*2=-8*2=-16
D because if you simpify 6/8 then that will give you 3/4
Answer:
The dimensions of the fort in the drawing is 7 in by 5.5 in
Step-by-step explanation:
A scale can be used to either increase or decrease the size of a given object.
From the question, Brennan used a scale of 3 feet to 1 inch.
scale = 
The dimensions of the fort are 21 ft by 16.5 ft. Thus, to determine the dimensions of the drawing;
= 
y = 
= 7 in
Also,
= 
z = 
= 5.5 in
Dimensions = y by z = 7 in by 5.5 in
Therefore, the dimensions of the fort in the drawing is 7 in by 5.5 in.
1 to 4
Step-by-step explanation:
Standard form for a parabola:
( x - h )² = 4 p ( y - k )
Vertex: ( h, k ) = ( -4, 2 )
Displacement from vertex to focus:
p = 2/8 = 1/4
( x + 4 )² = 4 · 1/4 ( y - 2 )
y = ( x + 4 )² + 2
or general form:
x² + 8 x - y + 18 = 0
