Answer:
A. 90 degrees clockwise rotation
Step-by-step explanation:
Of we have a coordinate axis (x,y), if this axis is rotated 90° clock wide, the resulting coordinate of the pre-image will be the coordinate (y -x). Note that the coordinates was swapped and then the new y coordinate negated.
Given the coordinate K(24, -15). If we rotate this clockwisely, first we swap the coordinate axis to have (-15, 24)
Them we will negate the new y coordinate axis to have;
K'(-15, -24)
Therefore the correct answer is 90° clockwise rotation.
Answer:
BC = EF = 8
Step-by-step explanation:
Assuming you mean BC ≅ EF, then ...
... 3z +2 = z +6
... 2z = 4 . . . . . . . . add -2-z
... z = 2 . . . . . . . . . divide by 2
BC = EF = 2+6 = 8
Answer:
C. -1
Step-by-step explanation:
Find the y intercept by plugging in the slope and a given point into the equation y = mx + b. Then, solve for b:
y = mx + b
-7 = -3(2) + b
-7 = -6 + b
-1 = b
So, the y intercept is -1.
The correct answer is C. -1
X= 50
Replace the x with the given number.
Y= 50-20
Y= 30
Answer:
Step-by-step explanation:
I assume that you need simplification of the given expression.
The given expression is:
Using distributive property and multiplying 2 inside the parenthesis and 1 inside the other parenthesis. This gives,
Therefore, is equal to:
Now, combining like terms using the commutative property of addition, we get:
Therefore, the simplified form is
