Answer:
see below
Step-by-step explanation:
1 1/4 > z
Open circle and 1 1/4 since there is no equals sign
line goes to the left since z is less than the number
-3x + 4 = 2x - 1
5x = 5
x = 1
When x = 1, y = 1
I'm not sure about the graph, but I solved them simultaneously? If you meant which graph but forgot to upload a photo attachment, look where it crosses the Y axis. If it is 4, it will be the first equation, if it crosses at -1, it will be the second equation
Answer:
y=10x+57
Step-by-step explanation:
30pieces of candy/3 minutes=10 pieces of candy/minute (slope)
He has already eaten 57 pieces at x=0 minutes so this must be the Y-Intercept
Slope intercept form is y=mx+b
m: Slope (10)
b: y-intercept (57)
A service call charge or fee is when you are charged a certain amount of money in order for a service technician to perform that specfic service.
Answer: (3x + 4y)(3x + 4y)
Step-by-step explanation: So you are supposed to "unfoil". So you would find two numbers multiplied together to make 9x^2 which would be 3x. Then you would find two numbers that can be multiplied together to get 16y^2 which would be 4y. To check your work, you do 3x times 3x. Then 4y times 4y. Then 4y times 3x plus 3x times 4y. You get 9x^2 + 24xy plus 16y^2.
