You would use the point-slope equation of y-y₁=mx(x-x₁)

So the rate of change is the slope and equals m, so m=-4

and has a solution at (-5,2) which would be the (x₁, y₁) and then it is just plugging in the numbers

y - (2) = (-4)(x - (-5))

y - 2 = -4 (x+5)

y - 2 = -4x - 20

y = -4x - 18

-4 = r divided by 20 − 5<br> Solve for R

Sidana [21]

Answer:

Step-by-step explanation:

Simplify both sides of the equation.

−4= r 20 −5 −4= 1 /20 r+−5 −4= 1 /20 r−5

Flip the equation.

1 /20 r−5=−4

Add 5 to both sides.

1 /20 r−5+5=−4+5

1 /20 r=1

Multiply both sides by 20.

20*( 1 /20 r)=(20)*(1)

r=20

Given mZ1= x° and m Z2 = (x +50)".

Tju [1.3M]

Given:

m∠1= x° and m∠2 = (x +50)°.

To find:

The value of x, m∠1 and m∠2.

Solution:

From the figure it is clear that, transversal side intersect the opposite sides which are parallel and form ∠1 and ∠2.

Sum of same sided interior angles is 180 degrees. So,

$m\angle 1+m\angle 2=180^\circ$

$x^\circ+(x+50)^\circ=180^\circ$

$2x^\circ+50^\circ=180^\circ$

$2x^\circ=180^\circ-50^\circ$

$2x^\circ=130^\circ$

Divide both sides by 2.

$x^\circ=65^\circ$

$x=65$

Now,

$m\angle 1=65^\circ$

$m\angle 2=(65+50)^\circ=115^\circ$

Therefore, the correct option is C.
