Step-by-step explanation:
1) Add 5x and 3x.
Now you have 8x = 5x + 15/2
2) Subtract 5x from the right side of the equation.
(You also do this to the left side)
Now you have 3x = 15/2
3) Now we want the value of x not 2 or 3x, so we will need to divide 3x by 3 to get the value of x.
3x/3 = 15/2 /2 (If the fraction divided by 3 looks confusing you can convert it into a decimal)
So you would have 3x/3 = 7.5/2
3x/3 = x
7.5/3 = 2.5
<h2>
x = 2.5</h2>

Answer:
D. No, because the differential equation does not have constant coefficients.
Step-by-step explanation:
The undetermined coefficient method cannot be applied to non homogeneous variables. The differential equation does not have constant variables therefore the method of undetermined superposition can not be applied. To complete a solution of non homogeneous equation the particular solution must be added to the homogeneous equation.
The answer is 700!
Multiply 175 times 4 which equals 700.
Or.... 175 divided by .25
Answer:
Step-by-step explanation:
5. You are asked to write an equation of the line in slope-intercept form, so you need to determine the slope of the line and the y-intercept.
You're lucky. One of the points, (0,1), has an x-coordinate of 0, so you know that the y-intercept is 1.
Use the coordinates of the points to determine the slope of the line.
slope = (difference in y-coordinates)/(difference in x-coordinates) = (10-1)/(3-0) = 9/3 = 3
The slope-intercept equation of the line is y = 3x+1

7. When x = 0, function A = 0 and function B = 3, so function B has a greater initial value.
x*5 - quarter amount
(x+15)*25- nickels amount
(x*5)+((x+15)*25)=735
5x+25x+375=735
30x=735-375
30x=360
x=360/30=12 - number of nickels
x+15=12+15=27 - number of quarters
CHECK
12*5=60 ¢
27*25=675 ¢
675+60=735 ¢ or $7.35
