What is the solution to the equation -4(2x+3) = 2x+6-(8x+2)?

aivan3 [116]

Answer:

x = -8

Step-by-step explanation:

-4(2x+3) = 2x+6-(8x+2)

Distribute

-8x-12= 2x+6-8x-2

Combine like terms

-8x-12 = -6x+4

Add 8x to each side

-8x-12 +8x = -6x+4+8x

-12 = 2x+4

Subtract 4 from each side

-12-4 = 2x+4-4

-16 = 2x

Divide each side by 2

-16/2 = 2x/2

-8 =x

A number cube is rolled 100 times. A 6 is rolled 40 times. What is the relative frequency for rolling a 6?

horsena [70]

The frequency would be 60%.
You know how many times she rolled the dice (100) then it also tells you the dice rolled 6 40 times. So then we minus 100 by 4. Which will end up getting us 60. Which we can also write as 60%. So the frequency is 60%.

What is the slope of the line that goes through (2,-3) and (-4,5)

Greeley [361]

Formula for slope: $\frac{y2-y1}{x2-x1}$
Plug in: $\frac{5-(-3)}{-4-2} = \frac{8}{-6} = -\frac{4}{3} or -1.333333
$
Slope: $- \frac{4}{3}$

Here's how to plug it into point slope if you'd like to know for future reference. :)
Formula for point-slope: $y - y1 = m(x-x1)$ where m = slope
Plug in: $y - (-3) = - \frac{4}{3}(x - 2)$
Solve: $y + 3 = - \frac{4}{3}x - \frac{13}{5} 
$
Add three both sides to get: $y = - \frac{4}{3}x + \frac{2}{5}$
And once you have solved, the above equation is now in slope-intercept form.
For further reference, slope intercept form is: $y = m(x) + b$

Drag the values into the boxes to classify each number as rational or irrational.

ycow [4]

The ones with ✓ signs are irrational the rest are rational. note this is not generally true but it is for this particular set
