Are you learning how to arc things
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.
Answer:
Option D, x = 1
Step-by-step explanation:
In order for that equation to equal to zero, you need the numerator (the top) to equal zero and the denominator (the bottom) to equal literally anything BUT ZERO.
To satisfy the first part we set the top binomial equal to zero.
x - 1 = 0
x = 0 + 1
x = 1
Plug in x = 1 to the bottom to see if it satisfies to second part; we're looking for everything but zero.
(x - 3)(x + 1)
(1 - 3)(1 + 1)
(- 2)(2) = - 4
Your answer is x = 1, option D.
Answer:
Here Two triangles BDE and BAC are similar as mentioned
So, According to Similarity of triangles theorem
BE/BC = DE/AC
4/16= x/20
1/4 = x/20
x= 20/4
x=5
