Answer:
the answer is A
Step-by-step explanation:
for parallel m1= m2
m2 = 3
formula = y - y1 = m2 ( x - x1)
= y = 3x - 29
We will see that g(x) is a reflection across the y-axis of f(x), then:

<h3>How to identify the function g(x)?</h3>
By looking at the graph, we can see that g(x) is a reflection across the y-axis of f(x).
So we can write:
g(x) = f(-x)
Here we know that:

Then, replacing f(x) on the formula for g(x), we get:

That is the function g(x) shown in the figure.

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.
The answer is D. Most of the other answers are way to high to make sense
To find x, substract 72 and 78 from 180 since all triangles are 180°
180 - 72 - 80 = 30
So x = 30
To find y, x and y equal 180 so subtract 30 from 180
180 - 30 = 150
y = 150
x = 30, y = 150
