Option C:
5, 1, 7
Solution:
Given equation:
y = |3x + 1|
In the chart, x values are given as –2, 0, 2.
To find the value of y for the corresponding x given.
Substitute x = –2 in the equation of y.
y = |3(–2) + 1|
= |–6 + 1|
= |–5| (Absolute value of a negative number is positive)
y = 5
Substitute x = 0 in the equation of y.
y = |3(0) + 1|
= |0 + 1|
= |1|
y = 1
Substitute x = 2 in the equation of y.
y = |3(2) + 1|
= |6 + 1|
= |7| (Absolute value of a negative number is positive)
y = 7
Option C is the correct answer.
The values of y are 5, 1, 7.
The answer image of the table is attached below.
If he need 380 to buy the bike but already has35, the he needs 380-35 = 345 more. if he makes 15 a week delivering papers, divide 345 by 15 to get the number of weeks it will take to save. 345/15=23 23 weeks
the student is wrong because the Constant coefficient is 5 not 3.
constant coefficient is that which have no variable but in the opinion of the student the coefficient is 3 which have a variable x.
so the student is wrong.
The first one is 90
The second one is 108
