Suppose that the minimum score on certification test is 200 and the maximum score is 1000. Write an absolute value equation that
represents the minimum and maximum scores. Use x to represent the scores.
1 answer:
Answer:
| x - 600 | = 400
Step-by-step explanation:
Absolute value equation of the form:
| x - a | = b
can be solved by:
x - a = b
x = a + b
and
x - a = -b
x = a - b
We can write the inequality | x - 600 | = 400
Let's solve and see if we get values of 200 and 1000:
x - 600 = 400
x = 1000
and
x - 600 = -400
x = 200
So this equation is right.
| x - 600 | = 400

Find K
when y=4 & x=5
Y=k/x^2

4=k/25
K=4*25
=100
When x

Y=100/2^2
Y=100/4
Y=25
