Answer:
no solution
Step-by-step explanation:
Given
(6x + 12) - 2(x - 7) = 19 ← distribute parenthesis on left side
2x + 4 - 2x + 14 = 19 , that is
18 = 19 ← not possible
This indicates the equation has no solution
We can set this problem up as an algebraic equation, which we can then solve to find our answer.
We start at -3. So we can start our equation with that:
However, this doesn't represent any change in temperature, just that we start at -3. To show change, we will use the variable , where
stands for the number of hours. Each hour accounts for a change of -2.5 in degrees, meaning that we must multiply our
by -2.5. We can now add this term into our equation:
We are trying to find when we will reach -18 degrees, so we will set our entire equation equal to -18 and solve:
It will take us 6 hours, or choice A.
Answer:
reflect over the x-axis
Step-by-step explanation:
Transformation is the movement of point from its initial location to a new location. Types of transformation is rotation, reflection, translation and dilation.
If a point A(x, y) is rotated 180° clockwise about the origin the new position would be A'(-x, -y)
If a point A(x, y) is reflected over the y-axis the new position would be A'(-x, y).
If a point A(x, y) is reflected over the x-axis the new position would be A'(x, -y)
If a point A(x, y) is translated a units left the new position would be A'(x-a, y).
The rectangle has points at (2, 2), (2, 5), (7,2), (7,5). If the rectangle is reflected over the x-axis the new position would be at (2, -2), (2, -5), (7, -2), (7, -5) which is at the fourth quadrant
