Answer:

The answer is 108.

Step-by-step explanation:

This can be solved with a simple proportion. 5/12 = 45/1. For 5 to become 45, you need to multiply by 9. You do the same to the denominator. 12 times 9 is 108.

<h2>Answer:</h2><h2>The expressions that can be subtracted from 9x to result in the expression 3x+5 is 6x - 5</h2>

Step-by-step explanation:

To find the expression that can be subtracted from 9x to result in the expression 3x+5.

Let us consider the expression, a - b = c

Here a = 9x

the result, c = 3x + 5

b = ?

Substitute the values in the above equation, we get

9x - (3x + 5) = b

b = 6x - 5

Step-by-step explanation:

y = a ( x − h ) ^ 2 + k

where vertex is (h,k) = (1,2)

h=1, k=2

y = a ( x − 1 ) ^ 2 + 2

sub ( 3,10)

10 = a (3 - 1)^2 + 2

a=2

y = 2 ( x − 1 ) ^ 2 + 2
