Answer:
n= -3.5
Step-by-step explanation:
n/7 - 12 = 5n +5
+12 +12
n/7 = 5n+17
*7 *7
n = (5n+17)*7
n = 35n + 119
-35n -35n
-34n = 119
/-34 /-34
n = -3.5
<span>Simplifying
4x + 8y = 30.60
Solving
4x + 8y = 30.60
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8y' to each side of the equation.
4x + 8y + -8y = 30.60 + -8y
Combine like terms: 8y + -8y = 0
4x + 0 = 30.60 + -8y
4x = 30.60 + -8y
Divide each side by '4'.
x = 7.65 + -2y
Simplifying
x = 7.65 + -2y</span>
Answer:
B (5,2)
Step-by-step explanation:
I love this unit a-lot (super fun)
So Congruent/Congruence is, For example If you have two triangles on a coordinates grid with the same coordinates than that would mean they're congruent. Shortened down would be
Same shape same coordinates same dimension same size (same everything)
Transformations would be Rotating a shape clockwise(CW)...right) or counterclockwise(CC Left)
Or Dilation which is making the shape smaller or bigger based on a scale factor.
Or reflection
How you would perform Reflection is reflect the shape over either the X-axis
Or the Y-axis
How you would perform a Translation would be to literally move the shape right left up or down.
How you would perform a Dilation(scaling) would be to pick a scale factor and either decrease or increase the size of the shape according to the scale factor number
How you would perform a Rotation would be to pick a point of rotation (P.O.R) and then pick your measure º such as 90º clockwise and rotate accordingly.
Hope it helps :)
