Answer:
x=-5
Step-by-step explanation:
I did a for #42
2(x-5)=3x+5
simplify
2x-10=3x+5
subtract 2x from both sides
-10=3x+5
subtract 5 from both sides
-15=3x
divide both sides by 3
-5=x
Answer:
Step-by-step explanation:
1) -28r +14=-12r-2
-16r=-16
r=1
~~~~~~~~~~~~~~~~
2) -35x+5=6x-36
-41x=-41
x=1
Answer:
28 x^3
Step-by-step explanation:
4x(7x^2)
4 * x* 7* x*x
4*7 x*x*x
28 x^3
Claim: The measures of
and
are equal
Answer: True
Explanation: Dilations preserve the shape of an image, so this means the angles are kept the same whether you shrink or enlarge the preimage.

Claim: The coordinates of A and A' are the same
Answer: True
Explanation: The phrasing "dilating about point A" means that point A is the center of the universe, so to speak, in terms of this dilation operation. Point A is the fixed point that does not move while every other point does move. Because the scale factor is 2/3, which is less than 1, this means every other point comes closer to point A. So something like segment AB will get shorter.
Answer:
x=79*
Step-by-step explanation:
136+60+85+x=360
281+x=360
x=360-281
x=79
