L=3w-4
Perimeter = 64
64=2L+2w
Plug in L that we solved above into this equation:
64=2(3w-4)+2w
64=6w-8+2w
64=8w-8
72=8w
w=9
Plug W back into the equation above to solve for L
L=3w-4
L=(3)(9)-4
L=23
Check the answer with the perimeter formula:
P=2L+2w
P=2(23)+2(9)
P=46+18
P=64
2x^2 - 3 = -4x - 1
2x^2 + 4x - 3 + 1 = 0
2^2 + 4x - 2 = 0 <==
Y-intercept: 0
Slope: 4
Explanation
Y-intercept is the number without the x which in this case is no number so it’s 0 so that’s where the point in the y axis goes
Slope is rise over run so if the equation is 2y = 8x then we can simplify this by dividing both sides by 2 which would be y = 4x so slope is 4/x. Which is basically 4/1 because the x means over one so up 4 units and to the right once
Hope this helps
