Simplify (write without the absolute value sign): |x−(−12)|, if x<−12

VladimirAG [237]

Answer:

|x + 12|

Step-by-step explanation:

The question I took form you I assume looks like this...

|x - (-12)|

Therefore, if we simplify this, the answer is |x + 12|

This is the answer because you would multiply -1 by -12

Tucker was asked to solve the equation 5x + 3 = 6x + 1. He did not know if his first step should be to add 5 negative x-tiles, o

Fittoniya [83]

It does not matter which he does first. Either way, zero pairs will be created on both sides, which will isolate the variable to determine x<span>. Adding the </span>x<span>-tiles and then the unit tile, or visa versa, will give the same solution.</span>

(Calculus help, 25 points, will give brainliest) Find the sum of the sigma notation below.

Andreyy89

$\displaystyle\sum_{i=3}^{10}(2i-9)=2\sum_{i=3}^{10}i-9\sum_{i=3}^{10}1$

Recall that

$\displaystyle\sum_{i=1}^n1=n$

$\displaystyle\sum_{i=1}^ni=\frac{n(n+1)}2$

Your sums start at $i=3$ , so in order to apply these formulas directly, you need to compensate for the missing first two terms:

$\displaystyle\sum_{i=3}^{10}1=\sum_{i=1}^{10}1-(1+1)=10-2=8$

$\displaystyle\sum_{i=3}^{10}i=\sum_{i=1}^{10}i-(1+2)=\frac{10\cdot11}2-3=52$

$\implies\displaystyle\sum_{i=3}^{10}(2i-9)=2\cdot52-9\cdot8=\boxed{32}$

The equation of line CD is y = −2x − 2. What is the equation of a line parallel to line CD in slope-intercept form that contains

aniked [119]

Answer:

$y=-2x+13$

Step-by-step explanation:

Equation of the line CD is given as $y=-2x-2$

Slope of the line CD = -2

Slope of the line parallel to CD = -2

Equation of the line parallel to CD is given by $y=mx+c$

$y=-2x+c$

But this line passes through (4,5)

Substituting the values in the equation:

$5=-2*(4)+c$

=> $c=5+8=13$

So the overall equation of the parallel line is given by $y=-2x+13$
