I think the answers would be D, B, false, B.
First we will obtain the original coordinates
A = (-3, 4)
B = (-1, 4)
C = (1, 1)
D = (-5,1)
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed).
The reflection of the point (x,y) across
the line y = -x is the point (-y, -x).
A' = (-4, 3)
B' = (-4, 1)
C' = (-1, -1)
D' = (-1, 5)
Answer:
Add 5 muffins
Step-by-step explanation:
If you add 5 more muffins the ration of muffins to corn bread will be 8:4, simplified, this is 2:1
Answer: a=24
Step-by-step explanation:
Lets find the line's formula (equation of the line).
As known the general formula of any straight line (linear function) is
y=kx+b
Lets find the coefficient k= (Yb-Ya)/(Xb-Xa)=(9-7)/(-4-3)=-2/7
(Xb;Yb)- are the coordinates of point B
(Xa;Ya) are the coordinates of point A
Now lets find the coefficient b. For this purpose we gonna use the coordinates of any point A or B.
We will use A
7=-2/7*3+b
7=-6/7+b
b=7 6/7
So the line' s equation is y= -2/7*x+7 6/7
Now we gonna find the value of a usingcoordinates of point C.
Yc=1, Xc=a
1=-2/7*a+7 6/7
2/7*a= 7 6/7-1
2/7*a=6 6/7
(2/7)*a=48/7
a=48/7: (2/7)
a=24
