In year 10, the table says the population is 25,000
But if we plugged x = 10 into the equation Lucy got, then,
y = 600x + 25000
y = 600(10) + 25000
y = 6000 + 25000
y = 31000
Lucy's equation says that the population in year x = 10 should be y = 31000 instead of 25000. So this is one way to show that there is an error. The output from the equation isn't matching what the table shows.
Answer:
A = 360
B= 180
C=270
Step-by-step explanation:
Answer:
x = 18 ; y = 10 ; z = 102°
Step-by-step explanation:
The triangle in the pic is an isosceles triangle.
As it is an isosceles triangle , it's two sides will be equal .



Also, both the base angles will be equal.



According to angle sum property of a triangle , sum of measure of all the angles of a triangle is equal to 180°. So,
