3x - y = 3.....3x - 3 = y
1/4x + 2/3(3x - 3) = -17/4
1/4x + 2x - 2 = -17/4 ...multiply everything by 4
x + 8x - 8 = -17
9x = -17 + 8
9x = - 9
x = -1
3x - y = 3
3(-1) - y = 3
-3 - y = 3
-3 - 3 = y
-6 = y
solution is (-1,-6)
Answer:
160 square feet
Step-by-step explanation:
you would do 2*8*10 to get 160 which would be your square surface area
Answer:
1 cm
Step-by-step explanation:
Since the perimeter is 4 cm and all the sides of the square have the same length, each side must be 1 cm long.
The area of that square is 1 cm x 1 cm, which is 1 cm2.
Answer:
x = 60
Step-by-step explanation:
The sum of the angles in a triangle is 180
40 + x+20 + x = 180
Combine like terms
2x+60 =180
Subtract 60 from each side
2x+60-60 =180-60
2x =120
Divide by 2
2x/2 =120/2
x = 60
Answer:
2,-4
-2,-3
_____
1
Step-by-step explanation:
That is how write the equation because you have to line them up by the higher x or y value
