telo118 [61]

$Solution, 3x-\frac{1}{2}y+\frac{22}{3}y-\frac{5}{6}x=\frac{13x+41y}{6}$

$Steps:$

$\mathrm{Group\:like\:terms}, =3x-\frac{5}{6}x-\frac{1}{2}y+\frac{22}{3}y$

$\mathrm{Add\:similar\:elements:}\:3x-\frac{5}{6}x=\frac{13}{6}x, =\frac{13}{6}x-\frac{1}{2}y+\frac{22}{3}y$

$\mathrm{Add\:similar\:elements:}\:-\frac{1}{2}y+\frac{22}{3}y=\frac{41}{6}y, =\frac{13}{6}x+\frac{41}{6}y$

$\mathrm{Multiply\:}\frac{13}{6}x\::\quad \frac{13x}{6}, =\frac{13x}{6}+\frac{41}{6}y$

$\mathrm{Multiply\:}\frac{41}{6}y\::\quad \frac{41y}{6}, =\frac{13x}{6}+\frac{41y}{6}$

$\mathrm{Apply\:rule}\:\frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}, =\frac{13x+41y}{6}$

The correct answer is $=\frac{13x+41y}{6}$

Hope this helps!!!

What is the equation in point slope form of the line that passes through the point (−2, 4) and has a slope of 5?

vodomira [7]

Answer:

$y-4=5(x+2)$

Step-by-step explanation:

We want to find the equation in point-slope form of the line that passes through the point $(-2,4)$ and has slope $m=5$ .

The point-slope form is given by the formula;

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

where $m=5$ is the slope and

$(x_1,y_1)=(-2,4)$ is a point on the line,

We substitute the values into the formula to obtain;

The required equation is $y-4=5(x+2)$

Which reason justifies step 2 in the proof

tigry1 [53]

<h3>Answer: C. If two lines are parallel, then the alternate interior angles formed are congruent.</h3>

This is through the alternate interior angles theorem. Angles Q and T pair up as one alternate interior set of angles that are the same measure. The same thing applies to angles X and R.

The identical arrow markers on segments XQ and TR show that those segments are parallel. Segment TQ is one transversal cut (forming alternate interior angles Q and T). Segment XR is the other transversal cut (forming alternate interior angles X and R).

We could say "angle XRT" or "angle TRX" instead of "angle R", though its ideal to use shortcuts whenever possible. The same applies for the other angles as well.

What is the length of LA?

Reptile [31]

You can solve this by setting up a proportion. 4/6 = x/9. Cross multiply to get 6x=36. Divide both sides by 6 to get x=6.
