multipl 10×2=20 y ese es el resultado entendes ?
The cost of one tv is double than cost of one DVD;
The cost of 2 tv is 4 times more cost one DVD ;
The cost of 2 tv and 3 DVD player is 7 times more cost one DVD ;Then, 1 DVD cost 1421 ÷7 = 201 $ ;
1 tv cost = 2 * 201 = 402 $ ;
Answer:
x = 78
y =64
z=102
Step-by-step explanation:
The three angles of a triangle add to 180 degrees
59+43+x = 180
102 +x = 180
Subtract 102 from each side
102-102+x = 180-102
x = 78
X and z form a straight line so they add to 180
x+z = 180
78+z =180
Subtract 78 from each side
78-78+z = 180-78
z = 102
The three angles of a triangle add to 180
14+z+y = 180
14+102+y =180
Combine like terms
116+y = 180
Subtract 116 from each side
116-116 +y = 180 -116
y = 64
Answer: x intercept= (-10,0) y intercept = (0,-40)
Just look at where the line hits the x axis for the x intercept, then those coordinates are your x intercept. Then for the y intercept, look at where the line meets the y axis and then that point's coordinates are your y intercept.
Hope this helps!
