adell [148]

ok so here we go:

1) (-6,-2.5),(-4,-3)\ m= -0.25 or  -\frac{1}{4}

2 )y=-0.25x-4 so the answer is (0, -4) or -4

3) y=\frac{3}{2}x+1 m=\frac{3}{2}

4) y=[tex]\frac{3}{2}x+1[tex] so the answer is (0, 1) or 1

A city receives an average rainfall of 16.99 centimeters in August one year during the month of August 15th then it rained anoth
AveGali [126]

Answer:

See explanation above

Step-by-step explanation:

This problem is very similar to one I solved a few moments ago. First we need to know how much it rain during the month of august the first 15 days of august. We only know how much it rain from the 15th through the end of the month.

So if you want to know the total rainfall of the month, you only need to sum the amount of the rainfall from the first 15 days of august and the last days of the month.

To help you out, I will use the same data of the other problem, which was 8.33 cm for the first 15 days, and 4.65 for the last 15 days of august.

If you sum 8.33 and 4.65:

8.33 + 4.65 = 12.98 cm

This would be (theorically speaking) the total rainfall during this month. Now, if it's the same exercise that you have, then good, use this answer, but if it's not then, all you need to do is put the value for the first 15 days and do the sum with 4.65 cm to get the total.

Which expression is equivalent to log3 c/9?
stepladder [879]
Hello!

There is an existing logarithmic property that states that log \frac{M}{N} is equal to log M-logN.

Following that property, we can tell that log \frac{c}{9} would be equal to log(c)-log(9).

ANSWER: log(c)-log(9) (third option)
