The vertex has a rotation (3,-2) --> (2,3).
Or in x and y coordinates, (x,y) --> (-y,x).
The rotation that has this said rule is R0, 90°. And 90° is equal to –270°.
The answers are:
R0, 90°
R0, –270°.
Additional information:
R0, 180° has the rule (x, y) → (-x, -y)
R0, 270° and R0, –90° has the rule (x, y) → (y, -x).

Range is calculated by substracting smallest value but highest value.

Answer:
ok
Step-by-step explanation:
8/m-9=6/m-8
Move -9 to the other side. Sign changes from -9 to +9.
8/m-9+9=6/m-8+9
8/m=6/m+1
Move +6m to the other side. Sign changes from +6m to -6m.
8/m-6/m=6/m-6/m+1
2m could also equal to : 1/2m
1/2m=1
Multiply by 2/1 for 1/2m and 1.
1/2(2/1)m=2/1(1)
Cross out 2 and 2, divide by 2. Cross out 1 and 1, divide by 1.
m=2
Answer: m=2
Answer:
<span>−84</span>
Explanation:
Let x be the unknown number.
From the queston we can form the equation
<span><span>x<span>(−7)</span></span>−2=10</span>
Move <span>−2</span> to the right hand side
<span><span><span>x<span>(−7)</span></span>=10+2</span><span><span>x<span>(−7)</span></span>=12</span></span>
Multiply both sides by <span>−7</span> to get the unkonwn no.
<span><span><span>−7</span>⋅<span>x<span>(−7)</span></span>=12⋅<span>(−7)</span></span><span>
x=−84</span></span>
Hope this helps
