Answer:
It is totaly based on the diagram
Answer: 23x
Step-by-step explanation:
Answer:
The required equation is: y=-3
Option D is correct.
Step-by-step explanation:
We need to write equation of line that is perpendicular to y = 5 and passes through (-4,-3).
The equation of line in slope-intercept form is expressed as: 
where m is slope and b is y-intercept.
Finding Slope:
Comparing with the given equation y=5, the slope m =0
The slope of required line will be opposite reciprocal of 0 as both lines are perpendicular. so it will be m=0
Finding y-intercept
The y-intercept can be found using slope m=0 and point (-4,-3)

So, y-intercept b is b=-3
The equation of required line having slope m=0 and y-intercept b=-3 is

So, required equation is: y=-3
Option D is correct.
Answer:
B, C, E are true
Step-by-step explanation:
A = l*w
The original rectangle is 6 by 4 with A = 24
The 1st enlargement = 6*3 by 4*3
18 by 12 with A = 216
The second enlargement is 18*3 by 12*3
54 by36 with A =1944
A.The area of the first enlargement is 72 square inches.
False it is 216
B.The area of the second enlargement is 1,944 square inches.
True
C.The area of the second enlargement is (3 squared) squared times the original area.
216/24 =9 True
D.The area of the second enlargement is 3 times the area of the first enlargement.
1944/24 = 9 False
E.The ratio of the area of the first enlargement to the area of the original equals the square of the scale factor.
The scale factor is 3 3^2 =9 216/24 =9
True
