What is the equation of the line described below written in slope-intercept form? the line passing through point (0, 0) and parallel to the line whose equation is 3x + 2y - 6 = 0 y =-2/3 -x y =-3/2x y = 3/2x

Answers

Since the line in question is parallel to the line with the equation 3x+2y-6=0, it can be said that they have the same slope. To find the slope of the line with the given equation, transform the given equation to its corresponding slope-intercept form. Hence, the equation is now

y=(-3/2)x+3

the slope is then -3/2

and since the line in question passes through the origin, the equation of this line is then

y=(-3/2)x+0
or simply
y=(-3/2)x

Answer:

y=(-3/2)x

It takes Jo 90 seconds to cut a a certain type of wood into 10 pieces. How long would it take Jo to cut the same wood type into 20 pieces?

Answers

so 90 seconds=10 pieces
10 pieces=9 cuts because just subtract 1 from number of pieces
2 pieces=1 cut
10 pieces=9 cust

90 seconds=9 cuts
10 seconds=1 cut

20-1=19
20 pieces=19 cuts
10 seconds per cut
10 times 19=190 seconds

it would take 190 seconds to cut into 20 pieces

In the space of 90 seconds Jo cuts a certain type of wood into 10 pieces.

Technically, this means that he had to strike that piece of wood 9 times.

So we can say that he strikes the piece of wood once every 10 seconds.

-----------------------------------------

If he continues striking the wood at this pace, it will take him 190 seconds to make 20 separate pieces of wood, as he'd have to make 19 cuts.

Here is the sequence of strikes:

10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190

-------------------------------------

The answer is 190 seconds.

Transform the polynomial into a perfect square trinomial to solvex^2-12x=13
a){46,55}
b){-1,13}
c){-15,27}
d){-21,33}

Answers

If you would like to solve x^2 - 12 * x = 13, you can do this using the following steps:

x^2 - 12 * x = 13
x^2 - 12 * x - 13 = 0
(x - 13) * (x + 1) = 0
1. x = 13
2. x = -1

The correct result would be b) {-1, 13}.

State if the three sies lengths form a right triangle ; 10 cm , 49.5 cm , 50.5 cm

Answers

Well, 10<49.5+50.5, 49.5<10+50.5 and 50.5<10+49.5
Because these conditions are obeyed, you have a triangle.
A right triangle requires that $50.5^2=10^2+49.5^2 \n 2550.25=100+2450.25$
which is true. So, the triangle has a right angle.
