For this case we have that by definition, the law of the signs of multiplication states that:

$+ * + = +\\+ * - = -\\- * + = -\\- * - = +$

So:

Option A:

$- * - * + = + * + = +$

It does not give a negative sign.

Option B:

$+ * - * - = - * - = +$

It does not give a negative sign.

Option C:

$+ * + * + = + * + = +$

It does not give a negative sign.

Option D:

$- * - * - = + * - = -$

The sign is negative.

Answer:

Option D

A population of rabbits doubles evey 4 months. if the population starts out with 8 rabbits how many rabbits will there be in 1 y

Airida [17]

If it doubles in every 4 months, then in 1 year it will double by 12/4 = 3 times.

So, the expression would be: n³
n = number of rabbit at starting point = 8

So, after 1 year, it would be = 8³ = 512

So, your final answer is 512

Hope this helps!

The sum of two numbers is 15. four times the smaller number is 60 less than twice the larger number. what is the larger number?

kirza4 [7]

X = smaller number, y = larger number
x + y = 15.....x = 15 - y
4x = 2y - 60

4(15 - y) = 2y - 60
60 - 4y = 2y - 60
60 + 60 = 2y + 4y
120 = 6y
120/6 = y
20 = y <==== larger number is 20

x + y = 15
x + 20 = 15
x = 15 - 20
x = - 5

A student writes the equation for a line that has a slope

levacccp [35]

Y = mx + c
Where
y is the y of (2, -8)
x is the x of (2, -8)
m is the gradient or slope
c is the y intercept (you don’t know what it is)

Put into equation and find c

Once find c rewrite the equation with only the m and c in numbers

Eg

y = 5x + 3 (this is an example not the answer)

Hope this is helpful if you don’t understand please comment
