A) You're just plugging in an "x" into the given equation here, and you need 8. I'd go with numbers that divide into whole integers by 8 (e.g. -4, -2, 2, 4), write down the x, then "y" after plugging into the equation.
B) Plot the coordinates you got from the first problem.
C) Any linear function has the domain of all real numbers, meaning that you can plug in any "x" and it'll work. What if you have a rational (something in the denominator) function though and x is in the denominator? Well, if we plug in any number and divide by 8, it works, BESIDES 0. You cannot divide by zero, and we call this "undefined" in math. There is no definitive nor quantitative answer, it is simply "undefined" because you can't divide something by 0
24÷6=4
it should be 4 out of 24 times
Answer:
x+y=28
70x+140y=3360
8 cats, 20 dogs were sold
Step-by-step explanation:
Let x=cats y=dogs
We know that a total of 28 pets were sold which means that
x+y=28
We also know that they made 3360 which means that
70x+140y=3360
It doesn't really say if you need to solve this but I will anyways
We use the first equation (x+y=28) and subtract 28 and y from both sides to get
x-28= -y we can then divide both sides by -1 so y can be a positive
-x+28=y
This is what y equals in terms of x and so we can plug this in for y in the second equation
70x+140(-x+28)=3360
Distribute the 140 and get
70x-140x+3920=3360
Add like terms and subtract 3920 to get
-70x=-560
divide both sides by -70 and get
x=8
We now know that 8 cats were sold and can plug this value into any equation to solve for y ( I will be using the first one because that's easiest)
8+y=28
subtract 8 and get
y=20
Answer:
depends on what B is,
Step-by-step explanation:
if you just want an equivalent equation. b^3-12b^2+b, but otherwise theres no way to answer without an inequality or equivalent equation without B
