Answer:
36f + 60g -36
Step-by-step explanation:
Multiply each term within the parentheses by 6
Answer:
2 right, 4 down, y-axis
Step-by-step explanation:
Reflection across the y-axis changes the left-right orientation. Reflection across the x-axis changes the up-down orientation. Translation before the reflection can put the figure in a place so that the reflection gives its final location. Translation does not affect the orientation.
__
We observe that the north-south wall is on the west side of the building at Site A, and on the right side at Site B. That means the orientation was changed left-to-right, so reflection was across the y-axis.
If the reflection occurred last, then the position before reflection must have the northeast corner moved from (-3, 5) to (-1, 1). That is, the x-coordinate is increased by 2, and the y-coordinate was decreased by 4.
The building at site A was translated <u><em> 2 </em></u> units right and <u><em> 4 </em></u> units down; then it was reflected across the <u><em> y-axis </em></u>.
I think you subtitute de 34 by x not sure
Answer:
y = 5x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (1, 4) and (x₂, y₂ ) = (2, 9)
m = = = 5 , then
y = 5x + c ← is the partial equation
To find c use any ordered pair from the table and substitute into the partial equation.
Using (3, 14 ) , then
14 = 15 + c ⇒ c = 14 - 15 = - 1
y = 5x - 1 ← equation of line
Answer:
x = -2
Step-by-step explanation:
2x + 5 = 4x + 7
2x = 4x + 7 - 5
-2x = 2
x = -2
