<h3>
Answer:</h3>
f((x, y)) = (-y, -x)
<h3>
Step-by-step explanation:</h3>
Rotation 90° CCW about the origin is the mapping ...
... (x, y) ⇒ (-y, x)
Reflection across the x-axis is the mapping ...
... (x, y) ⇒ (x, -y)
Together, these do the following mapping:
... (x, y) ⇒ (-y, -x) . . . . . . . equivalent to a reflection across y = -x
Expressed as a function, this might be written ...
... f((x, y)) = (-y, -x) . . . . . . . the ordered pair argument becomes a new ordered pair
17x>102
Divide both sides by 17:
x>6
you can take (128*32)+(102*32)=3520 tomatoes, then to find the price you multiply 3520 by 2 to get 7040 the equation is 2((128*32)+(102*32))=x
Answer:
r=11
Step-by-step explanation:
3x11=33
so therefore r=11
Given :
The temperature of a place was 32⁰C on Friday. On Saturday it rose by 4⁰C, then rainfall on Sunday caused the temperature to fall by 7⁰C.
To Find :
The final temperature on Sunday.
Solution :
Temperature on Saturday = initial temperature + 4⁰C
= 32⁰C + 4⁰C
= 36⁰C.
Temperature on Sunday = temperature on Saturday - 7⁰C
= 36⁰C - 7⁰C
= 29⁰C
Therefore, final temperature on Sunday is 29⁰C.
Hence, this is the required solution.
