First u have to make them all 3decimal places
Answer: the answer will be 10
Step-by-step explanation: Because you are subtracting 30-20 since it says what is the total change in the temperature. do you undeerstand now?
The answer is 22! Hope this helps
Answer:
(i) A"(-7, 6)
(ii) A"(3, 4)
Step-by-step explanation:
(i) The notation is a bit different. We assume it to mean that the transformation X is a translation 4 left and 2 up. That is, (-4, 2) gets added to the (x, y) coordinates:
(x, y) ⇒ (x -4, y +2)
For the coordinates A(1, 2), a transformation by X gives ...
A'(1 -4, 2+2) = A'(-3, 4)
We believe the notation X² is supposed to signify a second transformation by X. Then a second transformation by X of A' gives ...
A"(-3 -4, 4 +2) = A"(-7, 6) . . . A transformed by X²
__
(ii) Reflection in the line x=0 negates the x-coordinate, so the transformation Y is ...
(x, y) ⇒ (-x, y)
Applying this transformation to the result of translating A by transformation X, we get ...
A" = (-(-3), 4) = A"(3, 4) . . . A transformed by XY
Answer:
x=-2
Step-by-step explanation:
Let's solve your equation step-by-step.
5(x+6)+11=25−3x
Step 1: Simplify both sides of the equation.
5(x+6)+11=25−3x
(5)(x)+(5)(6)+11=25+−3x(Distribute)
5x+30+11=25+−3x
(5x)+(30+11)=−3x+25(Combine Like Terms)
5x+41=−3x+25
5x+41=−3x+25
Step 2: Add 3x to both sides.
5x+41+3x=−3x+25+3x
8x+41=25
Step 3: Subtract 41 from both sides.
8x+41−41=25−41
8x=−16
Step 4: Divide both sides by 8.
8x
8
=
−16
8
