Subtract 10x
10x + y = -19
10x + 3y = -17
You would get:
-2y = -2
Two negatives make a positive number! Divide
y = 1
Plug in
10x + (1) = -19
10x = -20
Divide
x = -2
Your solutions are
x = -2
y = 1
Answer:
-7

Step-by-step explanation:
Adjustments to income<span> are expenses that reduce your total, or gross, </span>income<span>. You enter </span>income adjustments<span> directly onto Form 1040 of your tax return. The amount remaining </span>after<span> deducting these expenses is "</span>adjusted<span> gross </span>income<span>."</span>
In this case, the ladder formed a triangle with the wall, you can see it in the attached diagram.
Let the distance of ladder from base of wall = x
Now to find the value of x, we use cosine ratio.
cos ∅= Adjacent / Hypotenuse
Put values
cos72= x/15
15 cos 72 = x
or
x=15 cos 72
x=4.6 ft ( Rounded to nearest tenth)
So, the distance of ladder from base of the wall is 4.6 ft.
