Answer:
1,452,000
Step-by-step explanation:
Round up 844 to 1,000.
Answer:
Step-by-step explanation:
Similar triangles
Cross multiply
2*(x+2) = 3*x
2x + 2*2 = 3x
2x + 4 = 3x
Subtract 2x from both sides
2x + 4 -2x = 3x - 2x
4 = x
x = 4
Answer: y= -1/5x + 3
15y= -3x + 45
y= -3/15x + 3
y= -1/5x + 3
We have
Therefore
We know: the line l passes through the point (-4, 3).
Substitute the coordinates of the point to the equation of a line l:
Answer: 
Answer:
B. (x, y) ⇒ (x, -y)
Step-by-step explanation:
When a point is reflected over the x-axis, it is moved along a vertical line to the same distance on the other side of the x-axis.
The x-coordinate of a point identifies its distance from the y-axis--the vertical line it is on. The y-coordinate identifies its distance from the x-axis. Changing the sign of the y-coordinate moves the point to the same distance on the other side of the x-axis--reflecting it over the x-axis.

The given points ABC and A'B'C' all match the pattern ...
(x, y) ⇒ (x, -y)
A(-1, 7) ⇒ A'(-1, -7)
B(6, 5) ⇒ B'(6, -5)
C(-2, 2) ⇒ C'(-2, -2)
so the image points represent a reflection over the x-axis of the original points.
