Answer:

A, or +10x

Step-by-step explanation:

(2x-3)(3x+5)\\6x^2+10x-9x-15\\6x^2+x-15

Given that a = 4.8 × 104 and that b = 8 × 10−3
Paha777 [63]

Answer:

3.84 * 10^0

Step-by-step explanation

Given the following values;

a = 4.8 × 104 and that b = 8 × 10−3

We are to find the product ab

ab = (4.8 × 10^4)(8 × 10^−3)

ab = (4.8*8)(10^4 * 10^-3)

ab = 38.4 * 10^(4-3)

ab = 38.4 * 10^-1

ab = 3.84 * 10 * 10^-1

ab = 3.84* 10^0

<em>Hence the product in standard form is expressed as 3.84 * 10^0</em>

Write an equation to represent the following description "fourteen less than 8 times a number is -11
Serggg [28]

Answer:

(8 * x) -14 = -11

Step-by-step explanation:

* = multiply sign (i didnt want to put "x" as the multiply sign since "x" is already being used) ( mightve confused you with 2 "x"s in the parenthesis.

x = the number that is missing being multiplied by 8

I put "8" multiplied by "x" in parenthesis since you do parenthesis first in an equation.

What is the equation of the line that passes through the point (-4,8) and has a slope of -1/4
iragen [17]

Answer:

Step-by-step explanation:

When a slope of a line and a point passing through it is given then we use slope - one point form to determine the equation of the line.

It is given by:

                      $ (y - y_1) = m (x - x_1) $

where $m$ is the slope of the line and

           $ (x_1, y_1) $ is the point passing through it.

Here, $ m = \frac{-1}{4} $ and $ (x_1,y_1) = (-4,8) $

Substituting in the equation:

$ y - 8 = \frac{-1}{4} (x + 4) $

$ \implies 4y - 32 = -x - 4 $

$ \implies x + 4y - 28 = 0 $
