999 because If you add one to 999 it's 1,000 and you'll go into the 4 digits

The biggest one is 999.

If you started counting from 1 to 999, you would count to 99
before you get to the first 3-digit number.

So there are (999 - 99) = 900 of them.

Answer:

Option B, $(48x^{8}y^{5})$

Step-by-step explanation:

<u>Step 1: Simplify the exponent</u>

$(12x^{2}y^{3})(2x^{3}y)^{2}$

$(12x^{2}y^{3})(2^{2}x^{3*2}y^{1*2})$

$(12x^{2}y^{3})(4x^{6}y^{2})$

<u>Step 2: Simply the expression</u>

$(12x^{2}y^{3}*4x^{6}y^{2})$

$(48x^{2+6}y^{3+2})$

$(48x^{8}y^{5})$

Answer: Option B, $(48x^{8}y^{5})$

Write an equation of a line in slope-intercept from with the given slope, slope:–3/4, y-intercept: –2

larisa [96]

Answer: y=-3/4x-2

Step-by-step explanation:

Write an equation of a line in slope-intercept from with the given slope, slope:–3/4, y-intercept: –2

The y-intercept is at (0,-2)

Then we write the equation using y=mx+b becuase that is the point slope form.

m=-3/4 which was given in the question

because y-intercept is at (0,-2)

y=-2

x=0

-2=-3/4(0)+b

-2=0+b

-2=b

now we know that m is -3/4 and b is -2

Hence the equation is y=-3/4x-2
