Yes they are congruent because they have just been translated in a rotation. But they still hold the same area and perimeter.
The answer is D) (-1,0) and (0,6). when you solve by substitution, all you need to do is solve for the variable in one equation and plug the answer into the other equation.
Find slope
(y2-y1)/(x2-x1) is slope
(11-3)/(1-(-1))=8/2=4
y=4x+b
input a point
(1,11)
x=1
y=11
11=4(1)+b
11=4+b
minus 4 from both sides
7=b
the equatin is
y=4x+7
the closest one
minus 4x from both sides
y-4x=7
times everybody by -1
4x-y=-7
last choice is answer
- 9x - 12 = 8 - 4x
- 9x - 12 (+ 12) = 8 (+ 12) - 4x
- 9x = 20 - 4x
- 9x (+ 4x) = 20 - 4x (+ 4x)
- 5x = 20
- 5x (/ - 5) = 20 (/ - 5)
x = - 4
I hope this helps :)
Answer:
The graph of the equation is shown in the picture attached below.
We can see w = 12 corresponds to the global maximum of the function, and for any w greater than 12 the value of A(w) decreases.
This means that for any value of the width greater than 12, the function cannot model the situation.
Making the equation only valid for
w ∈ [0,12]
