Hello from MrBillDoesMath!
Answer:
b = 0.6
Discussion:
The question can be written as
b - 7.4 = -6.8 => (now add 7.4 to each side)
b - 7.4 + 7.4 = -6.8 + 7.4 => ( note: -7.4 + 7.4 = 0)
b = 0.6
Thank you,
MrB
Answer:
The total cost to print n calendars is the sum of the cost of printing each calendar and the one-time cost for taking the photos:
Total cost = (Cost per calendar * Number of calendars) + One-time cost for photos
Given that the cost per calendar is $5.50 and the one-time cost for photos is $200, the equation can be written as:
Total cost = 5.50n + 200
Now, we know that the club has $1500 to cover the initial costs of the calendars. Therefore, the equation can be set equal to $1500:
5.50n + 200 = 1500
So, the equation representing the number of calendars the club can print is 5.50n + 200 = 1500, where n is the number of calendars.
Step-by-step explanation:
when the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs intersect at two places. Write the y-coordinates of the points of intersection in the boxes below in order from smallest to largest y=2x y+x^2 - 3
Answer:
Intersection points (1,2) and (-3,-6)
The y-coordinates of the points of intersection from smallest to largest is -6 to 2.
Step-by-step explanation:
Given : A system of equations and
To find : Write the y-coordinates of the points of intersection?
Solution :
Let,
and
Now, we plot these two equations.
The graph of is shown with red line.
The graph of is shown with blue line.
The solution to this system will be their intersection point.
The intersection points of these graph are (1,2) and (-3,-6).
Refer the attached graph below.
Therefore, The y-coordinates of the points of intersection from smallest to largest is -6 to 2.
Answer:
The correct answer is B. 10x - 12y
Step-by-step explanation:
To find this, we focus on just the like terms. So we break it down by the variable each time.
5x + 5x = 10x
-6y + -6y = -12y
z + -z = 0
So we put those answers all together to get 10 - 12y + 0 or just 10x - 12y
Step-by-step explanation:
It's D I believe.
