Since we have the y-intercept and the slope of the line, let’s use slope-intercept form:

y = mx + b, where m is the slope and b is the y-intercept.

y = -2/3x - 7

You will use the equation y=mx+b.

M is the slope and b is the y-intercept.

So since we already have both, all we have to do is plug it in.

y= - 2/3 -7.

Hope this helps!

What is the product?<br> (4x)(-3x^8)(-7x^3)
SashulF [63]

Answer:

84x¹²

Step-by-step explanation:

To simplify this expression, we work from left to right:

4x(-3x⁸)(-7x³)

Multiplying the coefficients of the first two, we have 4(-3) = -12.  Using the laws of exponents, multiplying powers with the same base means we add the exponents; this gives us x(x⁸) = x¹⁺⁸ = x⁹.  This gives us

-12x⁹(-7x³)

Multiplying the coefficients, we have -12(-7) = 84.  Using the laws of exponents, for the variable we have x⁹(x³) = x⁹⁺³ = x¹²

This gives us

84x¹²

Last year, 20,820 people attended a kite festival. This year, 19779 people attended it. If attendance continues to decrease by t
ICE Princess25 [194]

Well you start by dividing 19779 by 20820 to see the percent of people compared to last year (it being 95%). Then you take 19,779 and multiply it by the same percentage, or 0.95. That means that there should be 18790 (it's technically 18790.1 but since that's people you round to the nearest whole number).

Solve for x. Show your work with proper statements and notation.
9966 [12]

Answer:

x = 26

Step-by-step explanation:

The sum of the angles around point O = 360°, thus

x + 3x + 256 = 360 , that is

4x + 256 = 360 ( subtract 256 from both sides )

4x = 104 ( divide both sides by 4 )

x = 26
