It's a scale factor of 3. the way you find out is by counting from the center point to an edge point on the orignal. then do the same on the scales one. now divide the scaled one by the orignal and bam you get the answer
Just trinna get some points
f(x)=2x+5
first find inverse
write it without f(x)
y = 2x + 5
x = 2y + 5 swap the variables, now solve for y
- 5 -5
x - 5 = 2y
/2 /2 divide both sides by 2
(x-5)/2 = y
so f-1(x) = (x-5)/2
f-1(8) = (8-5)/2
= (3)/2
f-1(8) = 3/2
Answer:
7g - 3
Step-by-step explanation:
2g + 15 + 3g + g + g - 18
2g + 3g + g + g + 15 - 18
7g - 3
Answer:
3 (a/3) = a
Step-by-step explanation:
a/3 + a/3 + a/3
3 times a/3
the 3's cancel each other out
A
Keep up the good work! =)
