Answer:
y = -2x -1
Step-by-step explanation:
slope intercept form is y = mx +b
m = slope, b = y intercept
point is given as ordered pair (x,y)
plug in slope into y=......
y= -2x+b
plug in the point
3 = -2 * (-2) + b
3= 4 +b subtract 4 on each side
b = -1
y = -2x -1
to be honest, i think you can just convert that to 1 to 1.
Triangle ABC:
AB=2
BC=x+5
CA=x+7
Triangle XYZ:
XY=4
YZ=?
ZX=4x-2
x=?
XY/AB=ZX/CA
4/2=(4x-2)/(x+7)
Simpliying:
2=(4x-2)/(x+7)
Solving for x: Cross multiplication:
2(x+7)=(4x-2)
2x+14=4x-2
2x+14-2x+2=4x-2-2x+2
16=2x
16/2=2x/2
8=x
x=8
Answer: The value of x is 8
Answer:
oii sou islaine e tenho 1anosme manda mensagem fofo vc tem namorada gatinho me manda mensagem taaa agora me manda ta
-5 =(8m+12)/4
multiply each side by 4
-20 = 8m + 12
subtract each side by 12
-32 = 8m
Divide each side by 8
-4 = m
