I believe it is reflection across the Y-axis, followed by reflection across the X-axis.
Reflection is the mirror image of the shape across an axis.
Translation is the sliding down or up of the shape.

m<2=122°
m<3=58°

15) m<1=58°
m<2=122°
m<3=58°
m<5=122°
m<6=58°
m<7=122°
m<8=58°
If we know that 128 is 74% of something, we can write it like this:
74%x=128.
If we take the percent away (percent means by hundred in latin, 1%=1/100), we'll have
74/100 *x=128
//let's multiply both sides by 100, that way we can get rid of the ugly "/100 because 100/100 = 1, and we can ignore 1 in multiplications
100*74/100 *x = 128 *100// let's simplify the left side: 100/100=1
74*x=128*100// let's calculate the right side now
74*x=12800// now we have to divide both sides by 74
x=12800/74
if we divde this, we have: 172 + 72/74. (why? see below)
We can simplify the fraction by division by 2: 172 36/37

Answer:
y=3x-10
Step-by-step explanation:
For this, you would use the point slope formula, which is (y-y1)=m(x-x1). x1 and y1 are the coordinates from the ordered pair.
(y-y1)=m(x-x1)
(y-2)=3(x-4)
y-2=3x-12
y=3x-10
To check, you can plug the coordinates into the equation.
y=3x-10
(2)=3(4)-10
2=12-10
2=2
Answer:
1) yes 2) no 3) yes
Step-by-step explanation:
The lengths of the two shorter sides must be greater than the length of the longest side.
1) 8 + 9 > 10 yes
2) 1 + 1 = 2 no
3) 6 + 8 > 9 yes
