Solve the system of equations below by graphing both equations with a pencil and paper. y = -3 + 1 and y = -x + 5
1 answer:
Answer:
(-2,7)
Step-by-step explanation:
y=-3x+1 which is equivalent to y+3x=1
y=-x+5 which is equivalent to y+x=5
subtract the two equations :
y+3x-(y-x)=1-5
2x=-4
x=-2
substitute x in one equation : y+(-2)=5
y=5+2=7
check :
y+x=5
7-2=5
y+3x=1
7-6=1

Answer:
Triangle b = 4, h = 7
Step-by-step explanation:
Rectangle area = L*W
Triangle area = (B*H)/2
Rectangle/2 = Triangle
If you want triangle to = rectangle, then rectangle*2/2
Rectangle = 4*3.5 = 14
Triangle = 4*7 = 28/2 = 14
