Natural numbers: Counting things! You look around your room and see an electronic device, then another, then another! You just counted to 3 using the natural numbers.
Whole numbers! You try to look for electronic devices and realise that they’re all gone. You have zero electronic devices, and you just used whole numbers.
You go online to find where your electronic devices went, and realise they were taken because you’re in debt to the bank so they took some of your stuff. You’re in negative numbers, and now you’ve used integers.
Y = total costs to get the berries
x = pounds of berries.
bearing in mind that the $5 is just to get in, so is only paid once, whilst the pounds of berry will vary.
Answer:
No
Step-by-step explanation:
7 won't get you to 15 by multiply nor will 6 to 9
Answer:
3.2 is the highest value for k that will yield a non-negative discriminant
Step-by-step explanation:
For an equation to have real numbers as solutions, its discriminant (delta value) must be bigger than zero since there are no real square root solutions for negative numbers.
In this case, the discriminant is given by:
For k =3.2
As shown above, 3.2 is the highest value for k that will yield a non-negative discriminant and, therefore, if k > 3.2 the solutions of the expression are not real numbers.
Answer:
y=-3x+6
Step-by-step explanation:
(y2-y1)/(x2-x1)
(0-6) / (2-0)
0-6= -6
2-0= 2
-6/2= -3
slope is -3
so now we have y=-3x+b
in the coordinates (0,6) it means if x is 0 then y is 6. so the y-intercept is 6.
Therefore the equation would be y=-3x+6
