Answer:
12 inches
Step-by-step explanation:
You can use proportions to solve this:
1/10 = x/120
Cross multiply:
12 = x
Rearrange 0.16x^2+4.8xy+36y^2
Take 4 out 4(0.04x^2+1.2xy+9y^2)
Now its a square 4(0.2x+3y)^2
If we multiply it out
0.04x^2+0.6xy+0.6xy+9y^2
0.04x^2+1.2xy+9y^2
X = 82
a corresponding angle of 82 is also the vertical angle to x. This makes then equal.
To move a function up c units, add c to whole function
so down 7.5 is minus 7.5 from whole function
it would be y=|x|-7.5
