Reflect the shape A in the line x=1
1 answer:
Answer:
reflected image shown in red on attached diagram
Step-by-step explanation:
When reflecting an object in the line x = a:
- reflected x-values: 2a - x
- reflected y-values are the same as the original y-values
So when reflecting in the line x = 1
- given x-value = 2, so reflected x-value = 2(1) - 2 = 0
- given x-value = 4, so reflected x-value = 2(1) - 4 = -2
(2, 7) → (0, 7)
(2, 4) → (0, 4)
(4, 4) → (-2, 4)

Answer: 15
<u>Step-by-step explanation:</u>
small: 5 12 13
middle: __ 36 39
large: 45 108 117
Notice that to get from the small to the large, multiplied by 9
5(9) = 45 12(9) = 108 13(9) = 117
That is because the sides are proportional
To get from small to middle, multiply by 3
5(3) = 15 12(3) = 36 13(3) = 39
To solve it using proportions:
Answer:
x=2.4650
Step-by-step explanation:
I assume that you mean
so let s use the ln() function
so x = ln(15)/ln(3)
x = 2.4650
