. Solve the inequality. q + 12 – 2(q – 22) > 0 q > –32 q > 56 q < –32 q < 56
Given:
The inequality is
[tex]q+12-2(q-22)>0[/tex]
To find:
The solution of the given inequality.
Solution:
We have,
[tex]q+12-2(q-22)>0[/tex]
It can be written as:
[tex]q+12-2q+44>0[/tex]
[tex](q-2q)+(12+44)>0[/tex]
[tex]-q+56>0[/tex]
Subtract 56 from both side.
[tex]-q>-56[/tex]
Multiply both sides by -1 and change the inequality sign.
[tex]q<56[/tex]
Therefore, the correct option is D.
Answer:
D: q < 56Step-by-step explanation:

Step-by-step explanation:
The solution of the given equation is x = 2.1
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
For example, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
Given that, an equation, 3ˣ = 10, we need to find the solution of it,
So, solving for x,
3ˣ = 10
Taking log both sides,
㏒ 3ˣ = ㏒ 10
Since, ㏒ aⁿ = n ㏒ a
Therefore,
x ㏒ 3 = ㏒ 10
x = ㏒ 10 / ㏒ 3
x = 1/0.477
x = 2.095
x ≈ 2.1
Hence, the solution of the given equation is x = 2.1

Find the slope that passes through the two points. (9,3) and (6,7)
Answer:
m=4/-3
Step-by-step explanation:
the equation for slope (m) when given two points is (y2-y1)/(x2-x1)
we are given the points (9,3) and (6,7)
we can label the points:
x1=9
y1=3
x2=6
y2=7
now substitute into the equation
m=(7-3)/(6-9)
subtract
m=4/-3
the slope is 4/-3
