Solve for y 6x - 2y = 12 A. y= -3x + 6 B. y= 3x - 6 C. -3x + 6 D. -3x - 6

The answer is y=3x-6. (B). First you subtract 6x from both sides. Then you get -2y=12-6x. Now, you divide both sides by -2. This gets you the final answer; y=3x-6 or y=-6+3x.

Find the value of x that makes lines u and v parallel

gogolik [260]

Answer:

x = 4 for Lines U and V to be parallel

<u>Skills needed: HS Geo, Angle Theorems, Equations</u>

Step-by-step explanation:

1) We see that there are two angle measures given to us. There is an angle marked with the measure of $130$ °, and the other is marked with ( $33x-2$ )°.

First of all, these two angles are categorized alternate interior angles. They are on alternate sides of the transversal, and are within the two lines (not on the outer side of the lines). I will add an image for reference regarding this idea.
If 2 lines are parallel, alternate interior angles are congruent. This means that: $33x-2=130$

2) Solving this equation is fairly straightforward.

$33x-2+2=130+2$ (add 2 to both sides in order to get the $33x$ by itself.
$33x\div33=132\div33$ (to get $x$ by itself)
132 divided by 33 is 4, and 33x divided by 33 is x, so $x=4$

Find the surface area of the square pyramid below.

sleet_krkn [62]

Answer:

$\displaystyle 762,96\:m.^2 ≈ S.A.$

Step-by-step explanation:

$\displaystyle a^2 + 2a\sqrt{\frac{a^2}{4} + h^2} = S.A. \\ \\ 14^2 + 2[14]\sqrt{\frac{14^2}{4} + 19^2} = S.A. \\ \\ 196 + 28\sqrt{\frac{196}{4} + 361} ≈ 762,9567885 ≈ 762,96$

I am joyous to assist you anytime.

For what value(s) of x does y = 0 for the function tan(x)?

mina [271]

So We Know That tan(x) Equals

$\tan(x) = \frac{ \sin(x) }{ \cos(x) }$
We Can Use Logic, We Know That Anything That Makes The Denominator 0, Will Not Work, So We Need To Know What Makes Sin(x) equal to 0 and Cos(x) equal to 1 or -1 BUT NOT 0

$\sin(0) = 0 \: \cos(0) = 1 \\ \sin(180) = 0 \: \cos(180) = - 1 \\ \sin(360) = 0 \: \cos(360) = 1 \\ \sin( - 180) = 0 \: \cos( - 180) = - 1 \\ \sin( - 360) = 0 \: \cos( - 360) = 1$
$\cos(90) = 0 \\ \cos( - 90) = 0 \\ \cos(270) = 0 \\ \cos( - 270) = 0$
We Didn't Want Cosine To equal Zero Because Then We Get

$\tan(x) = \frac{ \sin(x) }{ \cos(x) } \\ \tan(x) = \frac{ \sin(90) }{ \cos(90) } \\ \tan(x) = \frac{1}{0} \\ \tan(x) = indeterminate$

THE ANSWER IS C : -360°,-180°,0°,180°,360°
