To express it in scientific notation, we have to write the first digit that appears after the zeroes, this is 2. Now, write the decimal dot after it and the others digits after that.

The exponent of 10 will be the number of zeroes in the left including the one that is before the decimal dot in negative form:

2.077\times10^{-4}

Leno4ka [110]

Answer:

Use the distributive property to multiply 3 by x−2.

y=(3x−6)(x+1)(x−4)

Use the distributive property to multiply 3x−6 by x+1 and combine like terms.  y=(3x  2  −3x−6)(x−4)

Use the distributive property to multiply 3x  2 −3x−6 by x−4 and combine like terms. y =3x  3 −15x  2  +6x+24

Step-by-step explanation:

I also up a link there of a graph. Please tell me if you can open it. Hope this helps! :P

Write the equation of the line that passes through A(-3,-2) and B(1,6).
topjm [15]

Answer:

<h2>y = 2x+4</h2>

Step-by-step explanation:

A(-3,-2) and B(1,6).\\\\x_1 = -3\\y_1 = -2\\x_2 = 1\\y_2 =6\\\frac{y-y_1}{x-x_1} =\frac{y_2-y_1}{x_2-x_1} \\\frac{y -(-2)}{x -(-3)} =\frac{6-(-2)}{1-(-3)}\\\frac{y+2}{x+3} = \frac{6+2}{1+3} \\\frac{y+2}{x+3} = \frac{8}{4} \\Cross-multiply\\4(y+2) =8(x+3)\\4y +8 =8x+24\\4y = 8x +24-8\\4y = 8x+16 \\OR\\ y = 2x+4
