x+2/2x-6=3/8 solve using multiplication property of equality
The solution to the equation given as x+2/2x-6 = 3/8 is x = -34/5
What are expressions?Expressions are mathematical statements that are represented by variables, coefficients and operators
How to solve using multiplication property of equality?The equation is given as
x+2/2x-6=3/8
Apply the multiplication property of equality.
So, we have
8(x + 2) = 3(x - 6)
Open the brackets
8x + 16 = 3x - 18
Collect the like terms
5x = -34
Divide both sides by 5
x = -34/5
Hence, the solution to the equation given as x+2/2x-6 = 3/8 is x = -34/5

Given a mean of 80 and a standard deviation of 3, label the normal curve below.
Answer:
The points from the left;
71, 74 , 77, 80, 83, 86 , 89
Step-by-step explanation:
Here, we want to label the normal curve given the mean and the standard deviation
From what we have, the central part is the mean while the other parts are deviations from the mean
We will label the graph starting from the left to the right
1 is 3 SD from the mean (negatively)
That will be 80-3(3) = 80-9 = 71
2 is 2 SD away
That will be;
80 -2(3) = 80-6 = 74
The 3rd part is 1 SD away
That will be 80-3 = 77
The midpoint is for the mean which is 80
The point after this will be;
80 + 3 = 83
The point after this will be;
83 + 3 = 86
Next is
86 + 3 = 89

What is the measure of angle x? (1 point)
1) 25 degrees
2) 40 degrees
3) 55 degrees
4) 105 degrees
Answer:
x=55degree because x+25=80 so x=55
Answer:
55°
Step-by-step explanation:
This is because that angle is 80° but is split into two and 80-25=55

Find the average rate of change of the function f(x)=(3/-3x-5), on the interval x ∈ [0,3]
Answer:
The average rate of change on the given interval is 9/70
Step-by-step explanation:
Here, we are to find the average rate of change of the function on the given interval
We proceed as follows;
on an interval [a,b] , we can find the average rate of change using the formula;
f(b) - f(a)/b-a
From the question;
a = 0
b = 3
f(0) = -3/5
f(3) = -3/14
Substituting the values, we have;
-3/14-(-3/5)/3-0
= 3/5-3/14/3
= (42-15)/70/3
= 27/70/3
= 27/70 * 1/3 = 9/70

Answer:
1. x = 1.5 rpm
2. x ≈ 0.8182 mi/hr
3. x = 6.6 feet
4. x = 4224 rpm
5. x = 390 rpm
Step-by-step explanation:
The relationship between angular speed and linear speed is given as follows;
Angular speed, ω = Linear speed, v/(Radius, r)
Therefore, we have;
1. When v = 12 cm/min = r = 8 cm , ω = 12/8 = 1.5 rpm
2. When, ω = 4 rpm, and r = 18 feet, v = 4 × 18 = 72 feet/min ≈ 0.8182 mi/hr
3. When, ω = 800 rpm, and v = 60 mi/hr = 1 mi/min, r = x = 1/800 miles = 6.6 feet
4. When v = 60 mi/hr = 63,360 mi/min, r = 15 in , ω = 63360/15 = 4224 rpm
5. When v = 13 in/sec = 780 in/min, r = 2 in, ω = 780/2 = 390 rpm

Which function is represented by the graph?
9514 1404 393
Answer:
f(x) = -2|x| +1
Step-by-step explanation:
The vertical translation is 1 unit upward, and there is no horizontal translation. So, the function will be something of the form ...
f(x) = a|x| +1
The slopes of the lines have a rise/run with a magnitude of 2/1, so the value of 'a' will have a magnitude of 2. The appropriate choice is ...
f(x) = -2|x| +1

Answer:
y = 65x + 250
Step-by-step explanation:
Let the linear equation representing the relation between total pay and number of computers sold be,
y = mx + c
Here, m = commission on every computer sold = slope of the linear function
c = weekly salary
y = total pay
x = number of computer sold each week
Since, slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the table attached,
Slope of the line passing through (4, 510) and (6, 640),
m = [tex]\frac{640-510}{6-4}[/tex]
= 65
Equation of the line will be,
y = 65x + c
Since, this line passes through (4, 510),
510 = 65(4) + c
c = 510 - 260
c = 250
Therefore, equation of the line will be,
y = 65x + 250
