Answer:

m= -5x+6y all over k

Step-by-step explanation:

first, move over 5x to get -5x+6y. then divide it by k and thats your answer.

Please help me solve thisss (ASAP)

Ksju [112]

The sum of complementary angles is 90 degrees, thus

3x + 6 + 3x + 18 = 90
=> 6x + 24 = 90
=> 6x = 90 - 24 = 66
=> x = 66 / 6 = 11

=> m<A = 3(11) + 6 = 33 + 6 = 39 degrees.

Consider the equation 1/3x−2=x+2. Write a system of linear equations using each side of the equation. Then solve the original eq

Ierofanga [76]

Answer:

(-6,4)

Step-by-step explanation:

1/3x − 2 = x + 2 is obtained by equating the following two functions:

y = (⅓)x - 2

y = x + 2

Graph:

Draw two straight lines

1) joining (0,-2) and (6,0)

2) joining (0,2) and (-2,0)

On the graph, you'll see that the above two lines intersect at: (-6,4)

Hence the solution is (-6,4)

For the function below, state the x-coordinate of the x-intercept that is located to the fight of the origin.

OLga [1]

Answer:

x = 3

Step-by-step explanation:

It should NOT be "fight of the origin", rather "right of the origin".

Now let's move on to solve the question...

The x-intercept is found by setting the function equal to 0. Thus:

0 = x^3 - 9x

Let's solve this using algebra:

$0=x^3-9x\\0=x(x^2-9)\\0=x(x-3)(x+3)$

Hence, x = -3 and x = 3

The coordinate that is to the right of the origin is the positive one, so x = 3 is the x-intercept we are looking for.
