Move a graph c units to right, minus c from every x
move a graph c units up, add c to every x
so basically
move 5 left means move -5 right or minus -5 from every x or add 5 to every x
move 3 up means add 3 to whole function
basically add 5 to every x and 3 to the whole function
example
if you had y=mx+b, then the translated function would be y=m(x+5)+b+3
A.
5 * 2 = 10
8 * 2 = 16
10 cm by 16 cm is the new dimensions. Area = 160 sq cm. Perimeter = 52 cm.
B.
5 * 3 = 15
8 * 3 = 24
15 cm by 24 cm is the new dimensions. Area = 360 sq cm. Perimeter = 78 cm.
C.
The areas for the different sized photos both still maintain a ratio of 5:8 cm.
Answer:
-8 < x < 13
Step-by-step explanation:
|2x-5|<21
The absolute value has 2 solutions, one positive and one negative. When we take the negative solution, we have to flip the inequality.
2x-5 < 21 and 2x-5 > -21
Add 5 to each side
2x-5+5 < 21 +5 2x-5 +5 > -21+5
2x < 26 2x > -16
Divide by 2
2x/2 <26/2 2x>-16/2
x <13 and x>-8
-8 < x < 13
Answer:
0.75 and -1.8333333...
sorry if wrong but i believe it is right
