Answer:
The coordinate of pre-image is, B(3 , -9).
Step-by-step explanation:
Given an image point has coordinate B'(7, -4).
We have to find the coordinates of its pre-image:
The rule of translation on pre-image (x, y) is given by;
then;
(7, -4) = (x+4, y+5)
on comparison we have;
x+4 = 7 and y + 5 = -4
First solve for x;
Subtract 4 from both sides we have;
x + 4 -4 =7-4
Simplify:
x = 3
To solve for y;
y+5 = -4
Subtract 5 from both sides we get;
y = -9
Therefore, the coordinate of pre-image is, B(3, -9)
Answer:
m∠4:55°
Step-by-step explanation:
this is because 2 and 4 are congruent to each other
Answer:
5≤u
Step-by-step explanation:
Put the words and numbers into an equation:
-5u+27≤2
Put all like terms on one side:
27-2≤5u ---> Do you see what I did there? Now you don't have to work with negatives. :)
Simplify:
25≤5u
Solve:
5≤u

Answer:
0.52
Step-by-step explanation:
Divide.
Answer:
Z = a - 2i - 3ib
Step-by-step explanation:
The complex conjugate has the expression with the opposite sign for the imaginary part.
Complex conjugate of Z=a + 2i + 3ib is,
Z = a - 2i - 3ib
