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)
Answers
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

. Solve the inequality. q + 12 – 2(q – 22) > 0 q > –32 q > 56 q < –32 q < 56
Answers
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:
The graph of which line intersects the graph of y + 10 = -5(x - 1) in only one point?
Answers
First, I’m going to the line is question into slope intercept form.
y + 10 = -5x + 5
y = -5x + 5 -10
y = -5x -5
y + 10 = -5 (x - 1) becomes y = -5x -5 in slope intercept form. I will call this line ‘line 1’
A becomes y = 5x -15 in slope intercept form
B becomes y = -5x + 25 in slope intercept form
C becomes y = -5x -5 in slope intercept form
D becomes y = -5x + 10 in slope intercept form
C is the same line as line 1. Any point that is on line 1 is also on line C, so C cannot be it.
Notice that line B and D have the same slope but different y-intercepts as line 1. That means these lines are parallel (not the same line though - different y intercepts) to line 1, so they will never intercept.
Line A has a different slope vs line 1, so they will eventually intersect only once

What is unit fraction?
A unit fraction is a rational number written as a fraction where the numerator is one and the denominator is a positive integer. A unit fraction is therefore the reciprocal of a positive integer, 1/n. Examples are 1/1, 1/2, 1/3, 1/4, 1/5, etc.
According to the question
The ratio 4:7 in the form n:1
i.e
[tex]\frac{4}{7} = \frac{n}{1}[/tex]
n = [tex]\frac{4}{7}[/tex]
Now, the unit fraction
The ratio is
= [tex]\frac{4}{7} : 1[/tex]
