Step-by-step explanation:
a) substitute x values:
6-2(0) = 6
6-2(1) = 4
6-2(2) = 2
6-2(3) = 0
6-2(4) = -2
6-2(5) = -4
b) rewrite equation as y=-2x+6.
this shows a negative slope with a y-intercept of 6.
c) 3=6-2x
-6 -6
-3 = -2x
divide both sided by 2
-3/-2 = x
3/2=x
-3(x+3)= -3(x+1)-5
-3x+9=-3x+3-5
so you would have just distributed then you combine like terms and get
-3x+9=-3x-2
then add two to both sides and get
-3x+9=-3x-2
-3x+2=-3x+2
-3x+11=-3x
+3x+11=+3x
0x+11=0x
so 11+0x
divide both by zero and you get x+0

Answer:
Step-by-step explanation:
1) ΔCPD & ΔEPF
∠CPD = ∠EPF { Vertically opposite angles}
∠CDP = ∠PFE {CD║EF, FD is transversal, Alternate interior angles are equal}
ΔCPD ≈ΔEPF {AA criteria for similarity }
Cross multiply
EF * 15 = 27 * 7.5
EF = 27 * 0.5
EF = 13.5 cm
ii) EF // AB, so Triangles ACB & ECF are similar triangles
AC = 37.5 cm
