Substitution method is one of the ways to solve this system.
-5x+y=4 and 4x-4y=16.
First we will divide the second equation with number 4 and get
x-y=4 => x=y+4 than we will replace x in the first equation
-5(y+4)+y=4 => -5y-20+y=4 => -4y=4+20 => -4y=24 => y=-6
x-(-6))=4 => x+6=4 => x=4-6=-2 (x,y)=(-2,-6)
Good luck!!!
1) corresponding pair <4 and <12
answer is a
2)
<2 = 133 (corresponding)
<2 = <5 = 133 (vertical angles)
answer a . 133
Answer:
192 = (x^2 + 8x)/2
Step-by-step explanation:
we know the base is x and the height is x+8.
Area of the triangle is 1/2 bh.
we know h and x
if we take area to be 192, we can write the area to be;
1/2 x(x+8) =A

Answer: The Answer would be 13.
