Step-by-step explanation:
f(x) = 2x + 5 = 45
2x + 5 = 45
2x = 45 - 5
2x = 40
x = 20
Answer is 13+21 , two negatives make a positive as a result the answer is A
Answer:
A) Dilated 150% then reflected across the x-axis
Step-by-step explanation:
By counting the squares of shape A, you can see that 2 squares = 100% and 1 square = 50%. You can then count 2 squares into shape B (because that is your starting point) and then count the remaining squares, which is 3. 3 squares is equal to 150% so we know there is a 150% dilation.
We can then also see shape A has been reflected across the x-axis to give shape B.
Answer:
3
Step-by-step explanation:
Using the rule of logarithms
x = n ⇒ x = 
let 
125 = n , then
125 = 
, that is
5³ =
Since the bases on both sides are equal, both 5 then equate the exponents
n = 3
