Answer:
x= 25.
Step-by-step explanation:
To isolate "x", I first moved all terms containing x to the left side of the equation: 0.32x-5=3 (0.4-0.08=0.32). Then moved all terms not containing x to the right side of the equation: 0.32x=8. Finally, I divided 8 by 0.32 which equals 25. Thus, x=25. I hope this helped!

What is the answer to this question?
A function is given. g(x) = 4 x + 7 ; x = 0, x = h (a) Determine the net change between the given values of the variable. Incorrect: Your answer is incorrect. (b) Determine the average rate of change between the given values of the variable. Incorrect: Your answer is incorrect.
Answer:
4hStep-by-step explanation:
We are expected to solve for the change given the following values of x
0,h
so we substitute x= 0 and x=h in the given expression, get the result, and subtract the results from each other
for x=0
[tex]g(x) = 4 x + 7\\\\g(0)=4(0)+7\\\\g(0)=0+7\\\\g(0)=7[/tex]
for x=h
[tex]g(x) = 4 x + 7\\\\ g(h)=4(0)+7 \\\\g(h)=4h+7 \\\\g(h)=4h+7[/tex]
The change would be
[tex]g(h)-g(0)= (4h+7)-7\\\\g(h)-g(0)= 4h+7-7\\\\g(h)-g(0)= 4h[/tex]

One number is 13 more than the product of 9 and another number. If the sum of the two numbers is 103, find the two numbers.
Answer:
x + y = 103 Subtract 2nd from 1st EQ
-10y = -90
y = 9 and x = 94 9%2A9%2B13
and...checking
sum = 103
Step-by-step explanation:
The two numbers are 9 and 94.
What are simultaneous equations?In mathematics, a set of simultaneous equation, also known as a system of equations or an equation system, is a set of equations for which common solutions are sought.
Let the two numbers be x and y.
Then according to question,One number is 13 more than the product of 9 and another number we have ,
13 + 9x = y
or,9x - y = -13...(i)
Also,the sum of the two numbers is 103. So we have,
x + y = 103 ...(ii)
Adding equation (i) and (ii) we get,
10x = 90
or, x = 9
Put the value of x in equation (ii), we get
9 + y = 103
or, y = 103 - 9
or, y = 94
Hence the two numbers are 9 and 94.

Find the distance between (-12, 1) and (12, -1) *
Answer:
[tex]d = 2\sqrt{145}[/tex]
Step-by-step explanation:
Use the Distance Formula to help you determine the distance between the two following points ( [tex](-12, 1)[/tex] and [tex](12, -1)[/tex] ):
-Distance Formula:
[tex]d = \sqrt{(x_{2} - x_{1}) ^2 + (y_{2} - y_{1})^2}[/tex]
(where [tex]( x_{1}, y_{1})[/tex] represents the first point, and [tex](x_{2}, y_{2})[/tex] represents the second point)
-Apply the following points to the equation:
[tex]d = \sqrt{(12 + 12) ^2 + (-1 - 1)^2}[/tex]
[tex]( x_{1}, y_{1})[/tex] = [tex](-12, 1)[/tex]
[tex](x_{2}, y_{2})[/tex] = [tex](12, -1)[/tex]
-Solve the equation:
[tex]d = \sqrt{(12 + 12) ^2 + (-1 - 1)^2}[/tex]
[tex]d = \sqrt{(24)^2 + (-2)^2}[/tex]
[tex]d = \sqrt{576 + 4}[/tex]
[tex]d = \sqrt{580}[/tex]
[tex]d = 2\sqrt{145}[/tex]
Therefore, the distance is [tex]2\sqrt{145}[/tex].
