Answer:

y = 3x

Step-by-step explanation:

Parallel lines have the same slope, so the slope of this new line will be the same as the given one.

For a line to pass through the origin it needs to have a y intercept of 0, because the origin is the point (0,0).

LuckyWell [14K]

Answer:

(A) 2 meter

Step-by-step explanation:

It is given that the ladder forms a 72º angle with the ground and rests against the house at a spot that is 6 meters high.

Let the measure of bottom of the ladder from the wall be x, then using the trigonometry, we have

\frac{CB}{AB}=tan72^{\circ}

\frac{6}{x}=tan72^{\circ}

\frac{6}{x}=3.077

x=\frac{6}{3.077}

x=1.94

x≈2m

Thus, option A is correct.

Help plz what is 7-6v=-5-8v
kirill115 [55]

<u><em>v=-6 is the right answer. </em></u> First you had to subtract by 7 from both sides of equation, and it gave us, 7-6v-7=-5-8v-7. And then simplify, and it gave us, -6v=-8v-12. You can also add by 8v from both sides of equation, and it gave us, -6v+8v=-8v-12+8v. Next simplify, and it gave us, 2v=-12. Then you divide by 2 from both sides of equation, and it gave us, \frac{2v}{2}=\frac{-12}{2}. And finally simplify, and it gave us the answer is <u><em>v=-6 is the right answer.</em></u> Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

Simplify 8 over negative 3 divided by negative 4 over 9 . (5 points) <br> -8<br> -6<br> 6<br> 8
denpristay [2]

Answer:

6

Step-by-step explanation:

(8/3) / (-4/9)

when dividing fractions you use the acronym k.c.f (keep change flip)

keep the first fraction

change the operation (divide to multiply)

flip the other fraction

(8/-3) x (9/4)

after re-writing your expression, you want to solve

do this by multiplying both numerators by each other and same with the denominators

(-8x9) / (3x-4)

then you get a new fraction,

-72/-12

simplify,

-72/-12 = 6 (multiplying/dividing 2 negatives will always give you a positive)
