Answer:
6:1
Step-by-step explanation:
1.8:0.3
each times by 10
18:3
each divided by 3
6:1
Answer: (-∞, 2)∪(2, 3]∪(4, ∞)
Step-by-step explanation:
Domain is the allowed x values in the function. The numerator, x + 1 will be defined for all numbers. But that fraction wont be, the minute that fractions denominator is equal to zero, your entire function becomes undefined.
So lets figure out what number will make this undefined. Then we'll know the functions domain is everywhere but that x value.
Make x^2 - 6x + 8 = 0
What two numbers multiply to equal +8 but add to equal -6? Thats -4 and -2.
(x - 4)(x - 2) = 0 This means the function is undefined when x equals 4 and 2
(-∞, 2)∪(2, 3]∪(4, ∞)
They estimated it by the last digit in 68,658. Since 8 is over 5, you round it up to 70,000. Another way to put it is that 68,658 is closer to 70,000 than it is to 68,000. Does that make sense?
Step-by-step explanation:
so, you don't know what a division is for ?
it is to ask things like "how often does one number fit into another number", or "how big will each piece be, if I split something into a certain number of equally sized pieces ?".
this is what we need here.
8 pizzas for $131.36. and each pizza costs the same. you see how that connects to what I just described above ?
to find how much each pizza cost, we need to divide the total price by 8, to find the size (= here the price) of each of the equally big parts of the total price.
131.36 / 8 = $16.42
Y=4x shows y as the total earnings and x as the number of windows
