1.for x it's 2x+5y=-1 you just do -5y on each side so you get 2x=-5y-1 then you divide it by 2 and it's x=-5/2-1/2
Other leg^ 2 = 20^2 - 12^2
other leg^ 2 = 400-144 = 256
then other leg = √256 = 16
Answer: question 2 is the 3rd option
Step-by-step explanation: thats all i remember from that
To make this easier, you need to change the fractions by multiplication.
-3/4x=15 - First, you multiply 4 to both sides of the equation
(4)-3/4x=15(4)
-12/4x=60 - Simplify
-3x=60 - Divide by -3 on both sides
x=-20 -> (-20,0)
Do the same to find the y-intercept, to get (0,18)
