Find the equation of a line that has the same slope ask why equals 10-4x and the same Y intercept is why equals -9x-8

Mathematics
1 answer:
Alborosie3 years ago
3 0

Answer:

y=-4x-8

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

so

1) Find the slope of the given line y=10-4x

The slope is m=-4

2) Find the y-intercept of the given line  y=-9x-8

The y-intercept is b=-8

therefore

The equation of the line with

m=-4

b=-8

is equal to

y=-4x-8

If the given values in a right triangle are cos A =
Vlad1618 [11]
See the picture attached to better understand the problem

we know that
in the right triangle ABC
cos A=AC/AB
cos A=1/3
so
1/3=AC/AB----->AB=3*AC-----> square----> AB²=9*AC²---->  equation 1

applying the Pythagoras Theorem
BC²+AC²=AB²-----> 2²+AC²=AB²---> 4+AC²=AB²----> equation 2

substitute equation 1 in equation 2
4+AC²=9*AC²----> 8*AC²=4----> AC²=1/2----> AC=√2/2
so
AB²=9*AC²----> AB²=9*(√2/2)²----> AB=(3√2)/2

the answer is
the hypotenuse is (3√2)/2

Do you agree or disagree with the following statement? Explain your reasoning. "Since the speed of the ball is different at each
xz_007 [3.2K]

Answer:

I disagree with the statement.

Step-by-step explanation:

Speed of the ball is different at each position:

This rhymes with the laws of physics because a ball placed at a certain height or on a certain slope will have a different speed (when thrown or rolled down) from a ball placed at a different height or on a different position on a plane.

There is no way to define probability density because i can't calculate the probability at just one point:

This statement is self-opposing as probability density is meant for times when probability value cannot be calculated or found for every given point! It is meant for continuous variables such as the one you're dealing with here - speed. The way to do this is to derive a probability density value for the variable in question (speed of the ball) for specific position intervals. Hence, divide the positions into intervals e.g.

A - B,   B - C,   C - D and so on.

So, probability density is used when you cannot the probability at just one point.

Can someone help pleaSE
aev [14]

Answer:

The correct answer is A) x = 1/4y^2

Step-by-step explanation:

Because the parabola opens to the side, we know that this is an x = equation. This allows us to eliminate both C and D.

Then we can determine that A is the correct answer due to the fact that it opens to the right. Negative lead coefficients always open to the left, so it could not be B

3•f(-4)-3•g(-2)=?<br> Help please
Scilla [17]

Answer:

3⋅f(−4)−3⋅g(−2) = −12f+6g

Step-by-step explanation:

Write the problem as a mathematical expression.

3⋅f(−4)−3⋅g(−2)

Move − 4 to the left of f .

3⋅(−4⋅f)−3⋅(g(−2) )

Multiply−4 by 3.

−12f−3⋅(g(−2) )

Move − 2 to the left of g .

−12f−3⋅(−2⋅g)

and lastly Multiply−2 by −3.

−12f+6g

Hope this helps you out.
