Answer:
11a - 2b
Step-by-step explanation:
Like terms can be further simplified.
3a + 8a -2b
= <u>11a - 2b</u> [ a and b are not like terms so they cannot be subtracted ]
Answer:
Step-by-step explanation:
1 Simplify brackets.
-3,9=-3,9,-3,-5−3,9=−3,9,−3,−5
2 Since -3,9=-3,9,-3,-5−3,9=−3,9,−3,−5 is false, there is no solution.

Answer:
- B
- B
- a) f(3y-1) = 24y -17; b) f(-7/4) = -23
Step-by-step explanation:
1. Any mapping requiring segment lengths to be congruent will require a "rigid" transformation, some combination of rotation, reflection, and translation.
If the transformation is not one of those, then segment lengths may change. The transformation we usually study that is not a rigid transformation is <em>dilation</em>. It preserves angles and slopes, but not segment lengths.
Of the choices listed, only choice B does not involve congruent segments.
__
2. In line with the discussion above, the dilation will preserve the slope of KM so that it is the same as the slope of K'M'. This is described by choice B.
__
3.
a) Finish simplifying the equation already written.
f(3y -1) = 8(3y -1) -9 = 24y -8 -9
f(3y -1) = 24y -17
b) f(x) = -23
8x -9 = -23
8x = -14 . . . . . . add 9
x = -14/8 = -7/4 . . . . divide by 8, reduce the fraction
x = -7/4 = -1.75
i cant see it its to blurry
A: coefficient 75, variable 35m, constant 25w
B:25x8=200+75=345
C:coefficient because instead of 75, it would be 95 changing the equation
Hopefully I did it right
