Distribute the -1/2 to both x and 12
-1/2(x) = -1/2x
-1/2(12) = -6
12 - (-1/2x) - 6
Simplify: Note, two negatives = one positive
12 + 1/2x - 6
Simplify: combine common numbers together
12 - 6 + 1/2x
6 + 1/2x
1/2x + 6 is your equivalent expression
hope this helps
Answer:
B
Step-by-step explanation:
D, as a frame goes around the entire photo, so having the perimeter would show the length of wood needed to surround the photo.
y =-3x + x + 9
Find y when x = 2
Substitute the value of x= 2 into the equation
y = -3(2) + 2 + 9
y = - 6 + 2 + 9
y = -4 + 9
y = 5
The answer is 5
Answer:
Step-by-step explanation:
Vertex A of the triangle ABC when rotated by 90° counterclockwise about the origin,
Rule to be followed,
A(x, y) → P(-y, x)
Therefore, A(1, 1) → P(-1, 1)
Similarly, B(3, 2) → Q(-2, 3)
C(2, 5) → R(-5, 2)
Triangle given in second quadrant will be the triangle PQR.
If the point P of triangle PQR is reflected across a line y = x,
Rule to be followed,
P(x, y) → X(y, x)
P(-1, 1) → X(1, -1)
Similarly, Q(-2, 3) → Y(3, -2)
R(-5, 2) → Z(2, -5)
Therefore, triangle given in fourth quadrant is triangle XYZ.
