Answer:
$ 312.17
Step-by-step explanation:
We have to want to save an emergency fund based on household expenses, the first thing is to calculate how much to save those 4 months would be:
702.38 * 4 = 2809.52
In other words, you will need $ 2809.52 to save for 4 months
Now we must divide by 9 because that is the number of months it will take to save, therefore:
2809.52 / 9 = 312.17
That is to say, $ 312.17 per month, for 9 months to save 4 months of expenses.
Y=0x+-9

The answer is $320.
In order to solve this, you can start off by turning this word problem into an expression.
$70x → $70 per hour (x represents the amount of hours)
+40 → plus $40 for the call
Substitute the x for 4 and solve the equation.
70x+40
70(4)+40
280+40
320
The plumber charges $320 for 4 hours of work.
The least common multiple of 3 and 8 is 24.
The least common multiple of two numbers is the lowest value number that is a multiple of both the numbers. To find the least common multiple of 3 and 8, you first list their multiples:
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24...
Multiples of 8: 8, 16, 24, 32, 40, 48, 56...
When you compare the two lists of multiples, you can see that the number 24 is the lowest number that is a multiple of both 3 and 8, so it is their LCM, or least common multiple.

Answer:
x=-6
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(6-2)/(-6-(-6))
m=4/(-6+6)
m=4/0
undefined
x=-6
