Answer: (-5,-5) --> (-x,-y)
Step-by-step explanation:
90 degree rotation: (-y,x)
180 degree rotation: (-x,-y)
270 degree rotation: (y,-x)
Answer:
perpendicular
Step-by-step explanation:
Rewrite the equations
y = (-1/7)x - 3/7 -- L1
y = 7x + 25 -- L2
Slope of L1 x Slope of L2 = -1/7 x 7 = -1
As a result, the two lines are perpendicular
Ok since you are solving for w, you remove the parentheses first w-(-7) it would convert to a +7, so the equation would be w+7=2 subtract the 7,on both sides to isolate the w. And w=-5.
Answer:
Slope=5/6 aka m=5/6

Answer:
Among the given statements the one which describes the properties of
Δ ABC and Δ A"B"C" is,
∠C and ∠C" are congruent after both the translation and dilation.
Step-by-step explanation:
Δ ABC is translated by the rule (x +1, y +1) and then dilated by a scale factor of 2 centered at the origin and the new triangle which we get is named as Δ A"B"C" .
Now, among the given statements the one which describes the properties of
Δ ABC and Δ A"B"C" is,
∠C and ∠C" are congruent after both the translation and dilation.
