Answer:
x = -3/7 x=1
Step-by-step explanation:
7x^2-4x-3=0
Factor
(7x+3)(x-1)=0
Using the zero product property
7x+3 =0 x-1 =0
7x = -3 x=1
x = -3/7 x=1
Given:
The inequalities are:
a)
b)
To find:
The solution of inequalities by substituting the given values.
Solution:
a) We have,
After substituting the given values one by one, we get
False statement.
False statement.
True statement.
True statement.
Therefore the solutions of are .
b)
We have,
After substituting the given values one by one, we get
True statement.
False statement.
False statement.
False statement.
Therefore, the solution of is .
Inverse operations is liek adding the negatie of a number to cancle it out or multiplying a fractin by its inverse to cancel it
so
19=(h/3)-8
add 8 to both sides
cancels the 8
19+8=(h/3)+8-8
27=(h/3)+0
27=h/3
times 3/1 both sides
27*3=(3h)/3
81=h(3/3)
81=h*1
81=h
