Answer:
-9 =x
Step-by-step explanation:
We know these are similar triangles
We can use ratio's to solve
Let CS = y  and XR = y+y or 2y
y           x+19
------ = ------------
2y         x+29
We can simplify the ratio on the left by dividing by y
1           x+19
------ = ------------
2         x+29
Using cross products
1(x+29) = 2(x+19)
Distribute
x+29 = 2x+38
Subtract x from each side
x-x+29 = 2x-x+38
29 = x+38
Subtract 38 from each side
29-38= x+38-38
-9 =x
 
        
             
        
        
        
Answer:
x-intercept: (-2, 0), y-intercept: (0, 10)
Step-by-step explanation:
First, we need to find the equation of this line. The formula to find the slope is:(y1-y2)/(x1-x2). Substituting the real numbers for this formula, (5-(-5))=10, (-1-(-3)=2. 10/2=5.
This means that the slope of this line is 5.
To find the complete equation for this line, we just need to plug in the x-value and add whatever needs to be added to attain the y-value. (You can plug in any x-value/y-value available.) 
5=5(-1)+?
-5+<u>10</u>=5.
The complete equation for this line is y=5x+10.
From here, the y-intercept is easy, because the number after the coefficient and variable (5 and x) are before the y-intercept (in standard form). The <em><u>y-intercept is (0, 10)</u></em> because if you plug in 0 for the x-value, you will get 10 as your y-value.
On the other hand, if you plug in 0 for your y-value and solve it out, you will get the x-intercept.
0=5x+10
-10=5x
x=-2
So the <em><u>x-intercept is (-2, 0)</u></em>.

Answer:
its c because parallel lines are lines  that are always the same distance apart all of these are the same distance apart 
hoped this helped let me know if it did
