Let the two numbers be x and y.
According to your question;
x + y = 7
10y + x = 10x + y + 9
By equation 1 ; x = 7-y
Substituting the value of x ;
10y + ( 7 -y) = 10(7-y) + y + 9
9y + 7 = 70 -10y + y + 9
9y + 7 = 70 - 9y + 9
=> 18y = 70 -7 + 9
=> 18y = 72
=> y = 4
Substituting for x ;
x = 7 - y
=> x = 7 -4
=> x = 3
Thus, x = 3 and y = 4;
=> The number is 34.

Step-by-step explanation:
The first step to finding the equation of this line we must find two points that are on this line.
Two points on the lines are (0,3) and (1,0).
Now we must find the slope:
Now after finding the slope which is -3, now let us put it into the point-slope form using the point (0,3) which is also on the line. You could also use (1,0) in this case, but I am using (0,3).
Thus the equation is

Answer:
D
Step-by-step explanation:
Using translation concepts, it is found that the transformed image of (5,-4) after the composition will be given by:
D.) (-6, 6)
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, first the image is rotated 180º around the origin, hence:
(x,y) -> (-x, -y), then:
(5,-4) -> (-5, 4).
Then, T(-1,2) means that:
(x,y) -> (x - 1, y + 2).
Then:
(-5,4) -> (-5 -1, 4 + 2) -> (-6,6)
Hence option D is correct.
