Answer:
a is the value of X
Step-by-step explanation:
Answer:
I assume you know Arithmetic Progression .
so, we have to find the first and last 4-digit number divisible by 5
first = 1000 , last = 9990
we have a formula, = a + (n-1)d
here, is the last 4-digit number divisible by 5.
n is the number of 4-digit even numbers divisible by 5
d is the common difference between the numbers, which is 10 in this case
a is the first 4-digit number divisible by 5
9990 = 1000 + (n-1)*10
899 = n-1
n = 900
Hence, there are 900 4-digit even numbers divisible by 5
The pair of points that are equal to x coordinates is (0,0)
Answer: y= -x +4
negative slope because our graph goes down as we go right.
+4 indicating how high on our y axis we go up/down
